Police Powers and Criminal Investigation in India: Arrest, Search, Seizure, Custodial Rights, and Procedural Safeguards

Police Powers and Criminal Investigation in India: Arrest, Search, Seizure, Custodial Rights, and Procedural Safeguards

Introduction

Police powers are among the most consequential forms of public authority in a constitutional legal system. Arrest, search, seizure, questioning, detention, and the collection of evidence allow law-enforcement agencies to investigate offences and protect public safety. At the same time, these powers can interfere directly with personal liberty, privacy, dignity, property, and the presumption of innocence. Their exercise must therefore be governed by law, constrained by constitutional guarantees, and subject to judicial oversight.

In India, the principal framework governing criminal investigation and police procedure is now the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which replaced the Code of Criminal Procedure, 1973 (CrPC) from 1 July 2024, subject to the statutory savings applicable to proceedings already pending at commencement. The BNSS regulates the registration of information about offences, police investigation, arrest, search and seizure, questioning, remand, the treatment of arrested persons, and the submission of police reports to criminal courts.

The BNSS operates alongside the Constitution of India, particularly Articles 20, 21 and 22, the Bharatiya Sakshya Adhiniyam, 2023 (BSA), which governs evidence, and other legislation dealing with particular offences, investigative institutions, and forms of digital or financial evidence. The resulting framework is not simply a catalogue of police powers. It is a system in which investigative authority is balanced against individual rights and procedural accountability.

This article examines the principal powers available to Indian police during criminal investigations, the legal conditions governing their exercise, and the safeguards intended to prevent arbitrary arrest, unlawful detention, coercive questioning, improper searches, and the misuse of seized material. It is an educational overview of Indian criminal procedure, not advice on the circumstances of an individual case.

1. The Legal Framework Governing Police Investigation in India

1. The Legal Framework Governing Police Investigation in India

The central statute is the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), Act No. 46 of 2023, which came into force on 1 July 2024. It consolidates and reforms the law of criminal procedure and replaces the CrPC for matters governed by the new regime. The official text is available through India Code – Bharatiya Nagarik Suraksha Sanhita, 2023. indiacode.nic.in+1

The BNSS must be read together with three other sources of law.

First, the Constitution of India establishes fundamental protections against arbitrary state action. Article 20 protects individuals against retrospective criminal punishment, double jeopardy and compelled self-incrimination. Article 21 guarantees that no person shall be deprived of life or personal liberty except according to procedure established by law. Article 22 provides specific safeguards for arrested and detained persons, including the right to be informed of the grounds of arrest, the right to consult and be defended by a legal practitioner, and production before a magistrate within twenty-four hours, subject to the constitutional exceptions concerning preventive detention.

Second, the Bharatiya Nyaya Sanhita, 2023 (BNS) defines criminal offences and their punishments. Police investigation ordinarily seeks to determine whether conduct constitutes an offence under the BNS or another applicable criminal statute.

Third, the Bharatiya Sakshya Adhiniyam, 2023 (BSA) regulates the admissibility and evaluation of evidence in judicial proceedings. The legality of a search or seizure and the evidential value of the material obtained are related but distinct questions. Evidence may be relevant to an investigation, yet its authenticity, method of collection, continuity of custody, and admissibility may still require judicial examination.

The BNSS is not the only source of investigative authority. Special statutes, including legislation concerning narcotic drugs, money laundering, terrorism, corruption, and other regulated activities, may confer additional powers on designated agencies. Such powers must be interpreted according to their statutory conditions and constitutional limits. A police officer investigating an ordinary offence under the BNS and an authorised officer exercising powers under a special statute may therefore operate under different procedural provisions.

The BNSS also contains territorial qualifications. Section 1 provides specific treatment for Nagaland and certain tribal areas, subject to the statutory exceptions and the possibility of extension by notification. The application of criminal procedure should consequently be assessed with attention to the relevant territory and any applicable local enactments or notifications. indiacode.nic.in+1

2. The Role of the Police in Criminal Investigation

The police are responsible for receiving information about offences, preventing crime, investigating suspected criminal conduct, identifying offenders, collecting evidence, and bringing the results of investigations before the competent criminal court.

Investigation is not equivalent to prosecution or adjudication. Police officers gather and assess material; prosecutors conduct proceedings on behalf of the State where prosecution is instituted; and courts determine questions of guilt, liability, admissibility, and punishment. This separation is essential. The police do not possess the authority to determine conclusively that a person is guilty merely because they have investigated or arrested that person.

The BNSS distinguishes between cognizable and non-cognizable offences. In a cognizable case, the police generally have statutory authority to investigate without first obtaining an order from a magistrate and may exercise specified powers of arrest without a warrant. In a non-cognizable case, the police ordinarily cannot investigate without the order of a competent magistrate, subject to the statutory framework.

The classification matters because it determines the initial procedural route. It does not mean that every cognizable offence automatically justifies arrest, or that every non-cognizable allegation is legally insignificant. The power to investigate and the power to arrest are separate questions. An officer may have authority to investigate a cognizable offence while still being required to demonstrate why arrest is necessary in the particular circumstances.

Under Section 175 BNSS, an officer in charge of a police station may investigate a cognizable case without an order from a magistrate, subject to the statutory jurisdictional framework. The provision also allows a magistrate empowered under the Sanhita to order an investigation in the circumstances specified by the law. Section 176 governs the procedure for investigation, including the reporting of information to the magistrate and the dispatch of an investigating officer or subordinate officer to examine the facts and circumstances of the case. IndiaCode+1

A criminal investigation should be directed towards discovering the truth, not merely confirming the initial suspicion. This means that investigators should examine material that may support the allegation as well as material that may undermine it. An investigation that deliberately ignores exculpatory evidence, relies on an untested assumption, or treats the accused as already guilty is inconsistent with the proper function of criminal procedure.

3. Registration of Information and the First Information Report

3.1 Information concerning cognizable offences

Section 173 BNSS regulates information relating to cognizable offences. Information may be provided orally or through electronic communication to the officer in charge of a police station, irrespective of the area in which the offence was committed.

Where information is given orally, it must be reduced to writing by the officer or under the officer’s direction and read over to the informant. The informant must sign the written record. Where information is communicated electronically, the statutory requirements concerning signature and recording must be observed.

The provision recognises the principle commonly associated with a Zero FIR: information about a cognizable offence should not be rejected merely because the offence occurred outside the territorial jurisdiction of the police station receiving it. The information can be recorded and the matter transmitted to the police station having the appropriate territorial jurisdiction.

This approach is particularly important where delay could endanger a victim, allow evidence to disappear, or impede the investigation. Territorial questions may be resolved through the appropriate transfer or coordination procedures rather than by refusing to record information at the outset.

3.2 Preliminary inquiry in specified cases

Section 173 also introduces a statutory preliminary-inquiry mechanism for certain cognizable offences punishable with imprisonment of three years or more but less than seven years. In the circumstances specified by the provision, and with prior permission from an officer not below the rank of Deputy Superintendent of Police, the police may conduct a preliminary inquiry to determine whether a prima facie case exists. The inquiry must be completed within the statutory period of fourteen days.

This is not a general permission to postpone the registration of every complaint. Its application depends on the offence category and the statutory conditions. The provision should be understood within the broader constitutional and judicial framework governing registration of information about cognizable offences.

3.3 Information concerning non-cognizable offences

Section 174 BNSS governs information relating to non-cognizable offences. The police must enter the substance of the information in the prescribed record and refer the informant to the magistrate. Investigation ordinarily requires an order from the competent magistrate.

Where a case involves several offences and at least one is cognizable, the statutory rules governing mixed cases may permit investigation of the case as a whole under the cognizable-offence framework.

3.4 The FIR is not proof of guilt

The First Information Report is an important procedural document, but it is not a judicial finding and does not establish that the named person committed an offence. Its purpose is to set the criminal process in motion and preserve the earliest account of the alleged occurrence.

The contents of an FIR may later be used for legally permitted evidential purposes, including corroboration or contradiction in accordance with the rules of evidence. However, the FIR is not ordinarily substantive proof of every fact stated in it. The court must assess the evidence produced during the proceedings.

The statutory framework for registration of information is set out in Sections 173 and 174 BNSS. IndiaCode+1

4. Police Powers to Investigate Cognizable Offences

Section 175 BNSS gives the officer in charge of a police station authority to investigate cognizable cases within the statutory territorial and subject-matter framework. The investigation may involve several activities, including:

• visiting and examining the scene of the alleged offence;
• identifying and interviewing witnesses;
• collecting physical, documentary, electronic, and forensic material;
• identifying and locating suspects;
• conducting searches and seizures where legally authorised;
• obtaining medical or expert examinations where permitted;
• examining relevant records and transactions;
• arranging identification procedures where necessary;
• seeking judicial orders for investigative steps that require them.

The statutory power to investigate is not unlimited. It must be exercised by an officer who is legally competent to act, for a legitimate investigative purpose, and in accordance with the applicable procedural safeguards.

Section 176 requires the police to report the relevant information to a magistrate and provides for investigation of the facts and circumstances. The provision also recognises that an officer may conclude that there is insufficient ground to investigate in a particular case. The decision must be made within the legal framework and cannot be used as an arbitrary device to suppress a genuine complaint.

A magistrate has supervisory functions within the statutory scheme. Depending on the circumstances, the magistrate may direct investigation or take other steps permitted by the BNSS. This judicial involvement is an important institutional check on police discretion.

The police investigation should also be distinguished from the judicial inquiry and trial. Police may form an investigative opinion, but the final determination of criminal responsibility belongs to the court.

5. Arrest Without a Warrant: General Principles

Arrest is one of the most serious powers available to the police because it directly restricts personal liberty. Indian law therefore distinguishes between the existence of a power to arrest and the justification for exercising it.

Section 35 BNSS governs the circumstances in which a police officer may arrest without a warrant. It permits arrest in specified situations, including where a person commits a cognizable offence in the presence of a police officer and where reasonable complaint, credible information, or reasonable suspicion exists concerning the commission of a cognizable offence.

However, the statutory conditions differ according to the seriousness of the offence.

5.1 Offences punishable with imprisonment up to seven years

Where the alleged cognizable offence is punishable with imprisonment for a term that may extend to seven years, whether with or without fine, Section 35 requires more than the existence of an allegation or suspicion.

The officer must have reason to believe, on the basis of the complaint, information, or suspicion, that the person committed the offence. In addition, the officer must be satisfied that arrest is necessary for one or more of the statutory purposes, including:

1. preventing the person from committing a further offence;
2. ensuring proper investigation;
3. preventing the person from causing evidence to disappear or tampering with it;
4. preventing the person from making inducements, threats, or promises to witnesses in order to dissuade them from disclosing relevant facts; or
5. ensuring the person’s presence before the court when required.

The officer must record the reasons for arrest. Where arrest is not required, the statutory framework also requires reasons for not making the arrest to be recorded.

The purpose of these requirements is to prevent arrest from becoming an automatic consequence of registration of an FIR or the naming of a person in a complaint.

5.2 Offences punishable with more than seven years or with death

Section 35 provides a different framework for offences falling outside the category of offences punishable with imprisonment up to seven years. The statutory grounds and applicable conditions must be examined according to the precise offence and the relevant provision.

The seriousness of an offence may justify more extensive investigative measures, but it does not remove the requirement that arrest be legally authorised and procedurally valid.

5.3 Notice of appearance instead of arrest

Where arrest is not required under Section 35, the police officer must issue a notice directing the person to appear before the police officer. The person is legally required to comply with the notice.

If the person complies and continues to comply with the notice, arrest should not ordinarily follow unless the officer records reasons showing why arrest has become necessary. If the person fails to comply, the officer may arrest in accordance with the statutory conditions.

This mechanism is important because it allows investigation to proceed without automatically depriving a suspect of liberty. It also recognises that cooperation with an investigation can often be secured through a lawful notice rather than custodial detention.

5.4 Additional safeguards for specified categories of persons

Section 35 contains further procedural safeguards, including a special restriction concerning the arrest of infirm persons and persons above sixty years of age in cases involving offences punishable with imprisonment of less than three years. The provision requires prior permission from an officer not below the rank of Deputy Superintendent of Police in the circumstances specified by the statute.

The purpose is to introduce an additional level of authorisation before arresting persons whose age or physical condition may make detention particularly intrusive.

The precise application of Section 35 must always be considered in light of the offence, the available material, the necessity for arrest, and any special statutory provisions. ncrb.mha.gov.in+2

6. Arrest Warrants and Arrest by Police Officers

Not every arrest takes place without a warrant. A competent criminal court may issue a warrant in accordance with the BNSS. A warrant is a formal judicial command authorising the arrest of the person identified in it, subject to its terms and the applicable law.

A warrant may be bailable or non-bailable. A bailable warrant permits release upon compliance with the specified bail conditions. A non-bailable warrant authorises arrest and production before the court but does not necessarily mean that bail is legally impossible. The question of release remains governed by the applicable bail provisions and judicial discretion.

The execution of a warrant must comply with the statutory requirements concerning identification, communication of the warrant’s substance, and production of the arrested person before the appropriate authority.

The BNSS also regulates arrest by private persons and arrest by magistrates. These are distinct from the ordinary exercise of police arrest powers and operate only in the circumstances specified by law.

The existence of an arrest warrant does not authorise unnecessary force or treatment inconsistent with the dignity and safety of the person arrested. The general safeguards governing arrest remain relevant.

7. The Procedure for Making an Arrest

Section 36 BNSS establishes procedural duties for the police officer making an arrest. These include proper identification of the officer, preparation of the arrest memorandum, and compliance with the prescribed requirements concerning witnesses and attestation.

The arrest memorandum is an important accountability document. It records that an arrest has occurred and helps establish the circumstances and timing of the deprivation of liberty.

The person arrested must be informed of the relevant particulars, and the prescribed procedure must be followed. Where a relative, friend, or other nominated person is to be informed, the statutory obligations under Section 48 must also be observed.

The BNSS further requires the designation of a police officer responsible for maintaining and displaying information about arrested persons. Section 37 provides for a designated police officer at district and police-station levels, subject to the statutory requirements. The Ministry of Home Affairs has identified this provision as one of the measures intended to increase transparency concerning arrests. pib.gov.in+1

7.1 Arrest by physical restraint

Section 43 BNSS regulates how an arrest is made. Ordinarily, the police officer must actually touch or confine the body of the person to be arrested unless the person submits to custody by word or action.

The provision also regulates the use of force and the circumstances in which handcuffs may be used. Handcuffing is not intended to be a routine or automatic practice. The statutory framework identifies specified categories and circumstances in which the use of handcuffs may be authorised, including certain serious offences and categories of repeat or dangerous offenders.

Even where the statute permits handcuffing, its use must remain consistent with the constitutional requirements of necessity, proportionality, and humane treatment. The authority to arrest does not create an unrestricted authority to inflict humiliation or unnecessary physical restraint.

7.2 Entry into premises to make an arrest

Section 44 BNSS addresses the situation in which a person sought to be arrested enters, or is present in, a place. It provides for entry and, in the circumstances specified by law, the use of necessary and reasonable force to gain access.

The power is subject to procedural restrictions. The officer must act within the statutory conditions, and special rules apply where the place is occupied by a woman who, according to custom, does not appear in public. The statutory protections concerning notice and reasonable opportunity to withdraw must be respected.

7.3 No unnecessary restraint

Section 46 BNSS expressly provides that an arrested person shall not be subjected to more restraint than is necessary to prevent escape. This reflects a wider principle of criminal procedure: detention must be directed towards lawful custody, not punishment before conviction.

The use of excessive force, humiliating treatment, or restraints unrelated to a legitimate security need may raise questions of statutory non-compliance and constitutional violation.

8. Rights of Arrested Persons

The rights of arrested persons arise from both the Constitution and the BNSS. They are not discretionary concessions granted by the investigating officer. They are legal safeguards intended to ensure that the process of arrest and detention remains accountable.

8.1 Right to be informed of the grounds of arrest

Article 22(1) of the Constitution provides that a person arrested must be informed, as soon as may be, of the grounds of arrest and must not be denied the right to consult and be defended by a legal practitioner of their choice.

Section 47 BNSS reinforces the obligation to communicate the grounds of arrest and to inform the arrested person of the right to bail where applicable.

The information must be meaningful. A vague statement that a person is being arrested in connection with an investigation may not adequately communicate the legal and factual basis of the arrest. The person must be informed sufficiently to understand why liberty is being restricted and to exercise available legal remedies.

The Supreme Court has emphasised the importance of communicating grounds of arrest in writing in particular statutory contexts. In its landmark judgment summaries, the Court has explained that the requirement under Article 22(1) is not satisfied merely by giving an abstract or formulaic reason. The grounds must convey the material basis for the arrest. India+1

8.2 Right to inform a relative or friend

Section 48 BNSS requires the police to inform a relative, friend, or other person nominated by the arrested individual about the arrest and the place where the person is being held, in accordance with the statutory procedure.

This safeguard serves several purposes. It reduces the risk of secret or unacknowledged detention, allows family members to locate the arrested person, and facilitates access to legal assistance.

The police must make the prescribed entry recording the fact that the nominated person has been informed. The obligation is an important part of the legal record of custody.

8.3 Right to consult a lawyer

Section 38 BNSS recognises the right of an arrested person to meet an advocate of their choice during interrogation, although not throughout the entire interrogation.

This right must be understood together with Article 22(1), which protects the right to consult and be defended by a legal practitioner. It does not mean that a lawyer must necessarily be present during every question or that the police cannot conduct a lawful interview. It does mean that the statutory opportunity to meet counsel must be respected.

Access to legal assistance is especially important where the person is unfamiliar with criminal procedure, faces a serious allegation, is vulnerable, or is being questioned in circumstances involving a risk of coercion.

8.4 Right to be produced before a magistrate

Article 22(2) requires that a person arrested and detained in custody be produced before the nearest magistrate within twenty-four hours of arrest, excluding the time necessary for the journey from the place of arrest to the magistrate’s court.

Section 57 BNSS similarly requires a person arrested without warrant to be taken before a magistrate or the officer in charge of a police station without unnecessary delay, subject to the provisions concerning bail.

The magistrate’s role is not merely administrative. Judicial production provides an opportunity to examine the legality of custody and determine whether further detention is justified under the statutory framework.

8.5 Protection against detention beyond twenty-four hours without judicial authority

Section 58 BNSS prohibits police detention beyond twenty-four hours, excluding the time necessary for the journey to the magistrate, unless further detention is authorised under Section 187.

The constitutional and statutory twenty-four-hour rule is a central safeguard against prolonged detention without judicial supervision. It does not mean that every arrested person must be released after twenty-four hours. It means that continued detention requires lawful judicial authorisation and cannot be extended solely at the discretion of the police. ncrb.mha.gov.in+1

8.6 Health and safety of the arrested person

Section 56 BNSS imposes a duty on the person having custody of an accused to take reasonable care of the health and safety of that person.

This obligation is relevant to medical treatment, protection from violence, access to necessary care, and the prevention of custodial abuse. It applies regardless of whether the allegation is serious or whether the arrested person has been granted bail.

The duty is consistent with Article 21 and the broader constitutional principle that a person does not lose their fundamental dignity upon arrest.

9. Arrest of Women and Other Vulnerable Persons

Indian criminal procedure contains additional safeguards for the arrest and treatment of women and certain vulnerable categories of persons.

Section 43 BNSS restricts the arrest of women after sunset and before sunrise, except in exceptional circumstances. Where exceptional circumstances exist, a woman police officer must make a written report and obtain the prior permission of the Judicial Magistrate of the First Class within whose local jurisdiction the offence is committed or the arrest is to be made, as provided by the statute.

The provision reflects the need to protect women from risks associated with arrest during night hours while allowing exceptions where legally justified.

The search of a woman must be conducted by another woman, with strict regard to decency. Section 49 BNSS provides this protection in relation to the search of arrested persons.

Medical examination provisions also contain safeguards. Where a woman is to be medically examined under the relevant statutory provisions, the examination must be conducted by or under the supervision of a female registered medical practitioner, as required by law.

Children and juveniles are subject to a separate legal framework, principally the Juvenile Justice (Care and Protection of Children) Act, 2015. A child alleged to be in conflict with the law is not simply to be treated as an adult accused under the ordinary arrest and detention regime. The special statute establishes distinct procedures, institutions, and protections.

Persons with disabilities, serious illnesses, or other vulnerabilities may also require particular attention. The police must comply with applicable statutory provisions, constitutional safeguards, and legal duties concerning communication, medical care, accessibility, and humane treatment.

10. Search of Persons and Premises

Search is an investigative measure intended to locate evidence, property connected with an offence, weapons, documents, or other relevant material. Because it interferes with privacy and property, it must be conducted under legal authority and in accordance with prescribed safeguards.

The BNSS regulates several types of search, including searches under warrants, searches conducted by police officers during investigations, searches of arrested persons, and searches of premises entered by a person sought to be arrested.

10.1 Search warrants

A magistrate may issue a search warrant where the statutory conditions are satisfied. A warrant may authorise the search of a particular place or the production or recovery of specified material.

The warrant should be read according to its terms. It does not create a general licence to search unrelated premises or seize any property that happens to be present. The scope of the search must correspond to the authority granted by the court and the applicable statutory provisions.

10.2 Search by police officers during investigation

Section 185 BNSS permits an officer in charge of a police station or an investigating police officer to conduct a search where there are reasonable grounds for believing that something necessary for an investigation into an offence may be found in a place within the relevant police-station limits and that it cannot otherwise be obtained without undue delay.

The officer must record the grounds of belief in writing in the case diary and specify, as far as possible, the object for which the search is to be made.

The search should, where practicable, be conducted by the investigating officer personally. The provision requires audio-video recording of the search, preferably by mobile phone. Where a subordinate officer is directed to conduct the search, the statutory requirements concerning written reasons and the written order specifying the place and object of the search must be observed.

A copy of the relevant record must be sent to the nearest competent magistrate within the statutory period, and the owner or occupier of the searched place may apply for a free copy through the magistrate.

These requirements are designed to create a documentary and audiovisual record of the search and to make the exercise of investigative discretion more transparent. IndiaCode+1

10.3 General safeguards during searches

Section 103 BNSS contains general provisions governing searches. Among other things, it regulates the presence of independent and respectable witnesses from the locality, the preparation of a list of things seized, and the handling of the search process.

The occupant of the place searched, or a person acting on their behalf, is generally entitled to attend the search. A copy of the list of seized items must be delivered to the occupant or the relevant person.

The search should be conducted with due regard to the dignity and privacy of persons present. Where a woman is to be searched, the statutory requirement that the search be carried out by another woman with strict regard to decency applies.

The use of independent witnesses and a written seizure list helps reduce disputes about what was found, where it was found, and whether the police removed items that were not connected with the investigation.

11. Audio-Video Recording of Searches and Seizures

One of the significant procedural features of the BNSS is Section 105, which requires the process of conducting a search or taking possession of property, articles, or things under the relevant chapter or Section 185 to be recorded through audio-video electronic means, preferably by mobile phone.

The recording must include the preparation of the list of things seized and the signing of that list by witnesses. The police officer must forward the recording without delay to the District Magistrate, Sub-divisional Magistrate, or Judicial Magistrate of the First Class.

This requirement has several important consequences.

First, it creates a contemporaneous record of the search. A recording may help establish whether the search took place at the stated location, whether the listed items were present, and how the police handled the material.

Second, it may reduce disputes between investigators and occupants about the manner in which a search was conducted.

Third, it supports judicial and administrative scrutiny. The recording is not intended merely for internal police use; the statute requires that it be forwarded to a designated public authority.

Fourth, it can assist in preserving the integrity of evidence. Where the seizure of a device, document, or physical object is disputed, the recording may provide context for assessing the chain of custody.

The provision does not eliminate every possible dispute. A recording may be incomplete, technically defective, interrupted, or challenged as inaccurate. Nor does the mere existence of a video automatically establish that every aspect of the search was lawful. The recording must be considered alongside the statutory authority, the written records, the seizure list, witness accounts, and the circumstances of the case.

Section 105 is therefore an accountability mechanism, not a substitute for the other safeguards governing searches. IndiaCode+1

12. Seizure of Property and Evidence

Search and seizure are related but distinct investigative powers. A search involves examining a person, place, or object to locate relevant material. Seizure involves taking possession or control of property under legal authority.

12.1 Seizure of suspected stolen or suspicious property

Section 106 BNSS authorises a police officer to seize property alleged or suspected to have been stolen, or property found under circumstances creating suspicion of the commission of an offence.

Where the officer making the seizure is subordinate to the officer in charge of the police station, the seizure must be reported to that officer. The statutory scheme also requires prompt reporting to the magistrate having jurisdiction.

The provision allows for practical arrangements where property cannot conveniently be transported to court, where appropriate accommodation cannot be secured, or where continued retention in police custody is unnecessary. In such cases, custody may be entrusted to a suitable person upon the execution of a bond undertaking to produce the property when required and comply with the court’s further orders.

This mechanism recognises that seizure does not always require indefinite physical retention by the police.

12.2 Property as evidence

Property may be seized because it is alleged to be stolen, because it may have been used in the commission of an offence, or because it may contain evidence relevant to an investigation.

Examples include:

• a weapon allegedly used in an assault;
• a vehicle connected with a criminal incident;
• documents relevant to a suspected fraud;
• electronic devices containing communications or records;
• goods suspected to have been stolen;
• financial records relevant to a suspected proceeds-of-crime investigation.

The legal basis for seizure depends on the relevant statute and circumstances. Investigators should be able to explain why the property is connected with the offence or investigation and why taking possession is authorised.

12.3 Inventory, preservation, and chain of custody

A seizure should be documented with sufficient detail to identify the property and establish how it came into police possession. Relevant information may include the description of the item, its location, the time and date of seizure, the persons present, the condition of the property, and the officer responsible for taking custody.

The chain of custody is particularly important in cases involving forensic or digital evidence. It records the movement, storage, examination, and transfer of material from the moment of collection until its presentation in court.

If the chain is inadequately documented, questions may arise concerning substitution, contamination, alteration, or loss of integrity. Such concerns do not necessarily mean that evidence must automatically be excluded, but they may affect its reliability and evidential weight.

13. Digital Devices, Electronic Records, and Forensic Investigation

Modern criminal investigations frequently involve smartphones, computers, cloud accounts, messaging services, CCTV systems, social media, location records, financial platforms, and network data.

The police may seek to obtain digital material through lawful searches, seizures, production orders, requests to service providers, forensic examinations, or procedures under special legislation.

However, the existence of information on a device does not automatically establish that its owner created it, knew of it, or controlled it. A phone may be shared, a computer may be accessed remotely, an account may be compromised, and metadata may require specialist interpretation.

A sound digital investigation should therefore address several separate questions:

1. Was the device or account obtained through lawful authority?
2. Was the material preserved in a manner that protects its integrity?
3. Can the investigator establish the source and authenticity of the record?
4. Is there a reliable connection between the record and the person alleged to have created or used it?
5. Has the material been altered, deleted, transferred, or generated automatically?
6. Does the record provide the context necessary for a fair interpretation?

Forensic imaging, hash values, metadata analysis, secure extraction methods, and documented access logs may help establish the integrity of digital evidence. Investigators should avoid unnecessary alteration of the original data and should record the methods used to obtain and examine it.

The BNSS provisions on search and seizure must be read together with the BSA provisions governing electronic and digital records. In particular, Sections 61–63 BSA address electronic records and their evidentiary treatment. The statutory requirements for proving electronic records in court are distinct from the police power to seize a device during an investigation.

The police may have lawful authority to take possession of a device, but the prosecution must still establish the authenticity and evidential relevance of the material it seeks to rely upon.

14. Medical Examination and Collection of Physical Evidence

Medical and forensic examinations may be important where an investigation concerns physical injury, sexual violence, poisoning, intoxication, identity, or other matters requiring specialist knowledge.

The BNSS provides for medical examination of arrested persons and accused persons in specified circumstances. Sections 51–53 regulate different forms of medical examination, including examinations requested by police officers and examinations of arrested persons by medical officers.

These provisions do not authorise arbitrary or unlimited bodily intrusion. The examination must be connected to a legitimate investigative purpose and conducted within the statutory conditions. The law also contains specific safeguards for examinations involving women.

Medical examinations may produce evidence such as injury descriptions, biological samples, toxicological findings, or other forensic material. The collection and preservation of such evidence should follow appropriate medical and forensic standards.

The dignity and physical safety of the person examined remain important. The investigative value of an examination does not remove the obligation to act lawfully, proportionately, and with due regard to privacy.

The evidentiary significance of medical findings must also be assessed carefully. A medical report may support or undermine an allegation, but it does not necessarily determine the ultimate question of guilt. The court must consider the report together with the other evidence.

15. Questioning and Interrogation of Suspects and Witnesses

Police questioning is a central investigative activity. It can help identify witnesses, clarify events, locate evidence, and test competing explanations. However, questioning must take place within the statutory and constitutional framework.

15.1 Attendance of witnesses

Section 179 BNSS authorises an investigating police officer, by written order, to require the attendance of a person who appears to be acquainted with the facts and circumstances of the case, subject to the territorial and statutory conditions.

The provision contains protections for specified categories of persons, including women, persons below fifteen years or above sixty years, persons with disabilities, and persons suffering from acute illness. In the circumstances prescribed by the law, such persons should not be required to attend at a place other than their residence.

These safeguards recognise that compelling attendance at a police station may create particular difficulties or risks for vulnerable persons.

15.2 Examination of witnesses by police

Section 180 BNSS permits the police to examine orally persons who appear to be acquainted with the facts and circumstances of the case. The person is expected to answer questions truthfully, subject to the statutory and constitutional protections.

The provision does not permit the police to use threats, inducements, or promises to obtain statements. Section 182 prohibits the offering of inducements and regulates the conduct of questioning.

15.3 Statements made to police

Section 181 BNSS regulates statements made to police during an investigation and their use in subsequent proceedings. Such statements are subject to statutory restrictions and are not generally treated as substantive evidence in the same way as testimony given before a court.

The rules are intended to prevent the prosecution from relying on untested police-recorded statements as though they were equivalent to sworn evidence. Their use is controlled by the statutory framework, including the rules governing contradiction of witnesses.

15.4 Confessions and self-incrimination

Article 20(3) of the Constitution provides that no person accused of an offence shall be compelled to be a witness against themselves.

The constitutional protection is particularly important during police interrogation. It prevents the State from compelling an accused person to provide testimonial evidence against themselves.

The BSA also regulates confessions made to police officers and confessions made while in police custody. The general rule is that confessions to police are inadmissible, subject to the limited statutory exception concerning information leading to discovery of a fact. This exception does not make the entire confession admissible; its operation is confined to the legally permitted portion.

The distinction between questioning a witness and interrogating an accused person is therefore important. Police may seek information during an investigation, but they cannot disregard constitutional protection against compelled self-incrimination or the statutory rules governing confessions.

16. Police Custody and Judicial Remand

Police custody and judicial custody are legally distinct forms of detention.

Police custody places the arrested person under the direct control of the investigating police for purposes authorised by law. It may be sought where investigators demonstrate that custodial interrogation or another investigative step is necessary.

Judicial custody places the arrested person under the authority of the court and ordinarily involves detention in a prison or other legally designated institution. The police do not exercise the same direct custodial control as they do during police remand.

16.1 The twenty-four-hour rule

Under Article 22(2) of the Constitution and Section 58 BNSS, an arrested person must be brought before a magistrate within twenty-four hours, excluding necessary journey time. Continued detention requires judicial authorisation.

The police cannot extend detention merely by stating that an investigation remains incomplete. They must apply to the magistrate under the statutory framework and provide the material required for the court to consider the request.

16.2 Section 187 BNSS

Section 187 governs the procedure where an investigation cannot be completed within twenty-four hours. The investigating officer must forward the arrested person and the relevant case-diary entries to the nearest magistrate, subject to the statutory requirements.

The magistrate may authorise detention in police or judicial custody as permitted by the provision. The BNSS modifies the framework for the timing of police custody and allows the statutory period of up to fifteen days of police custody to be authorised in parts during the initial forty days or sixty days of the applicable detention period, depending on the seriousness of the offence and the relevant statutory time limit.

The total permissible period for detention before the accused becomes entitled to default bail because the investigation report has not been filed remains linked to the statutory classification of the offence: generally sixty days for offences not falling within the more serious category and ninety days for offences punishable with death, life imprisonment, or imprisonment for a term of ten years or more, as prescribed by Section 187.

The precise calculation of the applicable period and the legal consequences of its expiry depend on the statutory text, the date of remand, the nature of the offence, and whether the accused has satisfied the conditions for release on default bail.

16.3 Judicial scrutiny of remand

The magistrate must exercise independent judicial judgment when considering a remand request. Detention should not be authorised mechanically. The court must consider the legal basis for custody, the material presented, the investigative necessity, and the statutory limits.

The principle is important because judicial remand is not intended to convert an unlawful arrest into a lawful one or to provide automatic approval for every request made by the investigating agency.cytrain.ncrb.gov.in+2

17. Custodial Violence, Torture, and the Protection of Human Dignity

Custodial violence is among the most serious threats to the rule of law. It may take the form of physical assault, threats, humiliation, deprivation of food or sleep, denial of medical care, sexual violence, coercive interrogation, or other treatment that violates the dignity and safety of a person in custody.

The Constitution applies to state conduct in detention. Article 21 does not cease to protect an individual because the person has been arrested or accused of an offence. The police have a duty to maintain custody lawfully and to protect the health and safety of detained persons.

The Supreme Court’s decision in D.K. Basu v. State of West Bengal (1997) is a landmark authority on safeguards against custodial abuse. The Court laid down requirements intended to improve accountability at the time of arrest and during detention. These include proper identification of officers, preparation of arrest documentation, notification of relatives or friends, recording of the time and place of arrest, medical examination, and maintenance of custody records.

The safeguards developed in D.K. Basu must be read alongside the current BNSS provisions and subsequent constitutional and statutory developments. They remain central to understanding the constitutional obligations of law-enforcement agencies.

An allegation of custodial violence may lead to several forms of legal scrutiny, depending on the facts:

• criminal investigation into the conduct of the officers involved;
• departmental proceedings;
• judicial examination of the legality of detention;
• constitutional remedies for violations of fundamental rights;
• compensation in appropriate cases;
• exclusion or challenge of evidence obtained through unlawful coercion, where the applicable law so provides.

A person in custody is entitled to medical attention where required. Injuries, complaints of mistreatment, and other relevant circumstances should be properly documented. Medical examination and custody records may become important evidence in subsequent proceedings.

The legal system must distinguish between legitimate investigative questioning and coercive treatment. The former is a lawful investigative function; the latter may constitute a serious violation of constitutional and criminal law.

18. Judicial Control and Remedies Against Unlawful Arrest or Detention

Judicial oversight is a central element of the Indian criminal justice system. Courts may examine whether police action complied with the Constitution, the BNSS, and any applicable special statute.

18.1 Production before a magistrate

The requirement to produce an arrested person before a magistrate within twenty-four hours provides an immediate form of judicial supervision. The magistrate may examine the circumstances of arrest and decide whether detention should continue.

18.2 Bail

Bail is an important mechanism for protecting personal liberty while ensuring that criminal proceedings can continue. The BNSS contains provisions governing bail in bailable and non-bailable offences, anticipatory bail, and the powers of courts to impose conditions.

The availability of bail depends on the offence, the applicable statutory provisions, and the circumstances of the case. Special statutes may impose additional restrictions.

18.3 Habeas corpus

Where a person is unlawfully detained or their whereabouts are concealed, a petition for habeas corpus may be brought before a competent constitutional court. The remedy requires the detaining authority to justify the legal basis for detention.

Habeas corpus is particularly significant in cases involving alleged secret detention, detention without lawful authority, or continued custody in violation of constitutional requirements.

18.4 Constitutional remedies

Article 32 enables a person to approach the Supreme Court for enforcement of fundamental rights, while Article 226 gives High Courts broad writ jurisdiction. These remedies may be relevant where police action violates constitutional protections.

18.5 Complaints and accountability mechanisms

Complaints concerning police misconduct may also be addressed through departmental processes, statutory oversight bodies, human rights institutions, or criminal proceedings, depending on the nature of the alleged conduct and the applicable legal framework.

The existence of a remedy does not automatically establish that a violation occurred. Courts and competent authorities must examine the facts, records, legal powers, and applicable standards.

19. Important Judicial Principles Governing Arrest and Investigation

Indian courts have developed principles that guide the exercise of police powers. Although the BNSS has replaced the CrPC for the new procedural regime, earlier Supreme Court decisions remain important where their constitutional reasoning or principles continue to apply and are consistent with the new statutory text.

19.1 Joginder Kumar v. State of Uttar Pradesh (1994)

The Supreme Court distinguished the legal power to arrest from the necessity of arrest. The fact that a police officer is legally empowered to arrest does not mean that arrest is justified in every case.

The decision emphasised that arrest should not be routine and that the officer must be able to justify the decision in the circumstances.

19.2 D.K. Basu v. State of West Bengal (1997)

This judgment established important safeguards designed to prevent custodial abuse and improve accountability. It remains a foundational authority on the constitutional treatment of persons in police custody.

19.3 Arnesh Kumar v. State of Bihar (2014)

The Supreme Court addressed unnecessary arrests in offences punishable with imprisonment up to seven years. It emphasised the statutory need to assess whether arrest is necessary and required police officers to record reasons for arrest or non-arrest in accordance with the then applicable CrPC.

The reasoning is particularly relevant to Section 35 BNSS, which retains and develops the statutory approach requiring necessity-based arrest in the relevant category of offences. The Supreme Court has continued to refer to the principle that arrest is not automatic and that officers must consider why arrest is required. api.sci.gov.in+1

19.4 Lalita Kumari v. Government of Uttar Pradesh (2014)

The Supreme Court considered the duty to register an FIR where information discloses a cognizable offence. The decision remains important to the legal understanding of police obligations when receiving information about alleged crime, although the BNSS now provides the applicable statutory framework and includes its own provisions concerning preliminary inquiry in specified cases.

19.5 Pankaj Bansal v. Union of India (2023)

The Supreme Court emphasised the importance of communicating grounds of arrest in writing in the context of the Prevention of Money Laundering Act. The judgment contributed to the broader discussion of meaningful communication of grounds of arrest under Article 22(1).

The application of the judgment must be considered in the context of the statute under which the arrest occurs and subsequent Supreme Court decisions.

19.6 The continuing importance of judicial review

Taken together, these decisions establish several recurring principles: arrest must be legally authorised; the power should not be exercised mechanically; the grounds and necessity of arrest matter; custodial safeguards must be observed; and courts retain authority to review unlawful deprivation of liberty.

They also demonstrate that criminal procedure is not simply a technical system for facilitating prosecution. It is a constitutional framework intended to reconcile effective law enforcement with the rights of individuals.

20. Special Investigative Powers Under Other Indian Laws

The BNSS provides the general framework for criminal investigation, but certain categories of offences are governed by special legislation. These statutes may confer additional powers on designated authorities, impose different arrest thresholds, or establish specialised procedures for investigation and prosecution.

20.1 Narcotic drugs and psychotropic substances

The Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act) regulates offences involving narcotic drugs, psychotropic substances, and controlled substances. It provides special powers concerning search, seizure, arrest, and investigation.

The Act contains detailed procedural provisions, including requirements concerning authorisation, recording of information, searches conducted by specified officers, and the handling of seized substances. Certain provisions also impose strict conditions for bail.

The existence of special powers does not remove the need to comply with statutory safeguards. Courts examine whether the relevant officers were authorised, whether the applicable procedural requirements were followed, and whether the prosecution can establish the integrity of the seized material.

20.2 Prevention of Money Laundering Act

The Prevention of Money Laundering Act, 2002 (PMLA) establishes a specialised framework for investigating money laundering and dealing with proceeds of crime. The Enforcement Directorate exercises powers under the Act, including statutory powers of arrest, search, seizure, and attachment in the circumstances prescribed by law.

PMLA proceedings should not be treated as identical to ordinary police investigations under the BNSS. The Act has its own definitions, authorities, procedures, and safeguards. Constitutional guarantees nevertheless remain relevant.

The Supreme Court has emphasised that statutory arrest powers under the PMLA are subject to judicial review. The authority exercising the power must comply with the statutory preconditions, and the arrested person must receive the information required by Article 22 and the applicable legislation.

20.3 Unlawful Activities (Prevention) Act

The Unlawful Activities (Prevention) Act, 1967 (UAPA) provides a special framework for offences relating to unlawful and terrorist activities. It contains provisions affecting investigation, detention, bail, and the role of designated agencies.

The National Investigation Agency Act, 2008 also establishes a specialised agency for investigating scheduled offences. The NIA’s powers and jurisdiction must be understood in the context of that legislation and the relevant provisions of the UAPA.

The special statutory framework may differ significantly from ordinary criminal procedure, particularly in relation to bail and investigation periods. Nevertheless, constitutional protections and judicial review continue to apply.

20.4 Prevention of Corruption Act

The Prevention of Corruption Act, 1988 regulates offences involving bribery and other forms of corruption by public servants. Investigation may be conducted by police officers or specialised agencies authorised under the statute.

The Act contains provisions concerning investigation, sanction for prosecution in specified circumstances, and the treatment of public servants. These requirements are intended to structure the exercise of investigative power and the institution of criminal proceedings.

20.5 Special statutes and general criminal procedure

Where a special statute establishes a specific procedure, that procedure may prevail over inconsistent general provisions to the extent provided by law. The BNSS may continue to apply where the special statute does not displace it or where the special legislation expressly incorporates general criminal procedure.

For this reason, the legality of an arrest or search should always be assessed under the statute that actually authorises the investigating officer to act. A power available to an officer under one enactment cannot automatically be assumed to exist under another.

21. Police Accountability and Institutional Oversight

Police powers require mechanisms of accountability because many investigative activities take place before a court has examined the allegations. Effective oversight helps ensure that statutory authority is exercised lawfully and that misconduct can be identified and addressed.

21.1 Internal police supervision

The BNSS and police administration framework provide for supervision by senior police officers. Depending on the case, supervisory officers may review investigative decisions, direct further steps, examine compliance with procedural requirements, and address failures in the conduct of an investigation.

Section 175 BNSS also recognises a role for the Superintendent of Police in requiring a Deputy Superintendent of Police to investigate a case having regard to its nature and gravity.

Internal supervision is important, but it cannot replace independent judicial review where liberty or fundamental rights are at stake.

21.2 Magistrates and courts

Magistrates exercise statutory oversight at several stages, including remand, certain investigative directions, search warrants, and the consideration of police reports.

The court’s role is not to conduct the police investigation itself. Rather, it ensures that investigative powers remain within the legal framework and that the rights of the accused and other affected persons are respected.

21.3 Human rights institutions

The National Human Rights Commission and State Human Rights Commissions may examine complaints involving alleged human rights violations by public authorities, including allegations of custodial abuse, unlawful detention, and excessive use of force, subject to their statutory jurisdiction and limitations.

Their work can complement criminal proceedings, departmental investigations, and constitutional remedies.

21.4 Judicial remedies and compensation

Where state action violates fundamental rights, constitutional courts may grant appropriate relief. In cases involving established violations of personal liberty or custodial rights, compensation may be awarded under public-law principles, depending on the circumstances.

Such compensation is distinct from any civil claim or criminal prosecution that may also arise. It is intended to provide a public-law remedy for a violation attributable to the State.

21.5 Transparency through records and technology

The BNSS’s requirements concerning arrest records, designated police officers, and audio-video recording of searches and seizures are part of a broader effort to make police action more traceable.

These measures are effective only if records are complete, recordings are preserved, statutory deadlines are respected, and supervisory or judicial authorities can access the relevant material when required.

Technology can strengthen accountability, but it cannot replace lawful decision-making. A recorded unlawful search remains unlawful; a properly completed arrest memorandum does not cure an arrest made without legal authority.

22. The Relationship Between Investigative Powers and the Presumption of Innocence

The presumption of innocence is a foundational principle of criminal justice. A person accused of an offence is not to be treated as guilty merely because an FIR has been registered, a search has been conducted, or an arrest has taken place.

Police investigation is a process of inquiry. It should test the available material and establish whether there is a legally sufficient basis for further proceedings. The prosecution must ultimately prove the charge according to the applicable standard of proof.

This principle has practical consequences for the exercise of police powers.

An arrest should not be used as a form of punishment or public demonstration of guilt. A search should not be conducted merely to intimidate a suspect. Seizure should not be used as an arbitrary means of depriving a person of property. Interrogation should not become a method of coercing a confession.

The rights of victims and witnesses are equally important. Police must take complaints seriously, preserve evidence, protect persons at risk, and investigate offences effectively. The presumption of innocence does not prevent the State from investigating or prosecuting credible allegations. It requires that those processes be conducted fairly and that guilt be determined by an independent court.

The legitimacy of criminal enforcement depends on both effectiveness and restraint. A system that cannot investigate offences fails victims and the public. A system that uses coercive or arbitrary powers undermines the rule of law and the credibility of criminal justice.

Conclusion

Police powers in India are extensive, but they are not unlimited. The Bharatiya Nagarik Suraksha Sanhita, 2023 provides the principal procedural framework for arrest, investigation, search, seizure, questioning, and custody. Its provisions operate within the wider constitutional structure, particularly Articles 20, 21 and 22, and alongside the Bharatiya Sakshya Adhiniyam, 2023 and applicable special criminal statutes.

The legal framework makes several important distinctions. The power to investigate does not automatically establish the necessity to arrest. An arrest does not establish guilt. A search must be supported by lawful authority and conducted in accordance with prescribed safeguards. Seized material must be properly documented and preserved. Continued detention requires judicial authorisation, and custodial treatment must respect the dignity and safety of the person detained.

The BNSS’s provisions on written reasons for arrest, notices of appearance, access to legal assistance, notification of relatives, judicial production, search records, and audio-video recording are intended to make the exercise of police power more transparent and accountable. Their practical effectiveness depends on proper implementation, institutional supervision, and the willingness of courts to examine alleged violations.

Ultimately, the relationship between police authority and individual liberty is not a contest in which one must eliminate the other. Effective investigation and constitutional protection are complementary requirements of a legitimate criminal justice system. Police must have sufficient authority to investigate offences, but that authority must remain subject to law, necessity, proportionality, and independent judicial control.

No. Registration of an FIR does not automatically justify arrest. The officer must assess the statutory conditions governing arrest and consider whether arrest is necessary in the circumstances.

5. What happens if arrest is not necessary?

Where arrest is not required under Section 35, the police must issue a notice directing the person to appear before the investigating officer, subject to the statutory requirements. Compliance with the notice ordinarily protects the person from arrest unless reasons for arrest subsequently arise.

6. What is a Zero FIR?

A Zero FIR is an FIR recorded by a police station even though the alleged offence occurred outside its territorial jurisdiction. The matter can subsequently be transferred to the police station having jurisdiction. Section 173 BNSS supports the recording of information irrespective of the area in which the offence occurred.

7. Must police tell an arrested person why they are being arrested?

Yes. Article 22(1) of the Constitution and Section 47 BNSS require the grounds of arrest to be communicated to the arrested person.

8. Does an arrested person have the right to contact a lawyer?

Yes. Article 22(1) protects the right to consult and be defended by a legal practitioner of the person’s choice. Section 38 BNSS recognises the right to meet an advocate of the person’s choice during interrogation, although not throughout the entire interrogation.

9. Must police inform the family about an arrest?

Section 48 BNSS requires the police to inform a relative, friend, or other nominated person about the arrest and the place of detention in accordance with the statutory procedure.

10. How long can police keep a person in custody without producing them before a magistrate?

Ordinarily, an arrested person must be produced before a magistrate within twenty-four hours, excluding the time necessary for the journey. Further detention requires judicial authorisation.

11. Can police question a person without arresting them?

Yes. Police may question witnesses and other persons in accordance with the BNSS. Section 179 permits an investigating officer to require the attendance of certain persons by written order, subject to statutory protections.

12. Can police force an accused person to confess?

No. Article 20(3) protects an accused person against compelled self-incrimination. The BSA also restricts the admissibility of confessions made to police officers, subject to the limited statutory discovery exception.

13. Can police search a house without a warrant?

In specified circumstances, yes. Section 185 BNSS permits an investigating officer to conduct a search without a warrant where the statutory conditions are met, including reasonable grounds for believing that relevant material is present and cannot otherwise be obtained without undue delay.

14. Must police record the reasons for a search without a warrant?

Yes. Under Section 185, the grounds for the search and the object sought must be recorded in writing in the case diary, so far as possible.

15. Must police record searches and seizures on video?

Section 105 BNSS requires the specified search and seizure processes to be recorded through audio-video electronic means, preferably by mobile phone. The recording must be forwarded without delay to the designated magistrate or other authority specified by the provision.

16. Can police seize a person’s phone or computer?

A device may be seized where a lawful statutory basis exists and the relevant conditions are satisfied. The seizure must be connected with a legitimate investigative purpose and comply with applicable procedural safeguards. The prosecution must separately establish the authenticity and evidential relevance of digital material relied upon in court.

17. Can police seize property suspected of being stolen?

Yes. Section 106 BNSS authorises seizure of property alleged or suspected to be stolen or found in circumstances creating suspicion of the commission of an offence. The statutory reporting and custody requirements must be observed.

18. Can police keep seized property indefinitely?

Seizure does not automatically justify indefinite retention. The BNSS provides mechanisms for reporting, custody, production, and disposal of seized property. The appropriate treatment depends on the nature of the property, the investigative need, and the orders of the competent court.

19. Can police handcuff an arrested person?

The BNSS permits handcuffing in specified categories and circumstances. It is not a general licence to handcuff every arrested person. The use of restraints must remain within the statute and constitutional requirements concerning necessity and humane treatment.

20. Are there special rules for arresting women?

Yes. Section 43 BNSS restricts the arrest of women between sunset and sunrise, subject to the statutory exception requiring written justification and prior permission from the competent magistrate. Searches of women must be conducted by another woman with strict regard to decency.

21. Are children arrested under the ordinary BNSS procedure?

Children alleged to be in conflict with the law are governed principally by the Juvenile Justice (Care and Protection of Children) Act, 2015. The special framework provides distinct procedures and safeguards and should not be confused with the ordinary adult arrest regime.

22. What is the difference between police custody and judicial custody?

Police custody places the arrested person under the direct control of the investigating police for authorised investigative purposes. Judicial custody places the person under the authority of the court, ordinarily in a prison or other designated institution.

23. Can a magistrate authorise police custody after the first twenty-four hours?

Yes, where the statutory conditions are met. Section 187 BNSS regulates remand and permits police custody within the statutory limits and time periods prescribed by the provision.

24. What is default bail?

Default bail is a statutory right that may arise where the investigation report is not filed within the applicable statutory period and the accused satisfies the conditions for release. Under Section 187 BNSS, the relevant period is generally sixty or ninety days, depending on the seriousness of the offence and the applicable statutory classification.

25. What can a person do if they are unlawfully detained?

Depending on the circumstances, remedies may include approaching a competent magistrate, seeking bail, filing a habeas corpus petition, or invoking the writ jurisdiction of the High Court or Supreme Court. Complaints to appropriate oversight bodies may also be available.

26. What is habeas corpus?

Habeas corpus is a constitutional remedy through which a court may require the authority detaining a person to justify the legality of the detention. It is particularly important where detention is alleged to be unlawful or unauthorised.

27. Can police use force during an arrest?

Police may use force only within the limits authorised by law and only to the extent justified by the circumstances. Unnecessary or excessive force may violate the BNSS and constitutional protections.

28. What protections exist against custodial violence?

Article 21, Section 56 BNSS, the procedural safeguards governing arrest and detention, and the principles established in D.K. Basu v. State of West Bengal provide important protections. Allegations of custodial abuse may lead to criminal, departmental, judicial, and constitutional proceedings.

29. Do special agencies have different arrest powers?

Yes. Agencies operating under legislation such as the PMLA, NDPS Act, UAPA, and NIA Act may exercise powers established by those statutes. The legality of their actions must be assessed under the relevant special legislation and the Constitution.

30. Does an arrest mean that a person is guilty?

No. Arrest is an investigative or procedural measure, not a finding of guilt. The accused remains entitled to the presumption of innocence, and criminal responsibility must be determined by a competent court according to the applicable standard of proof.
