⚠️ CRITICAL: READ THIS FIRST

An arrest is one of the most serious actions that can be taken against a person, depriving them of liberty and freedom. Understanding when police can legally arrest you and what rights you possess during arrest is fundamental knowledge that every citizen must have. This guide will empower you with comprehensive legal knowledge to protect yourself.

Understanding Arrest: The Legal Foundation

An arrest is the act of depriving a person of their liberty through legal authority, usually for the purpose of criminal investigation or prosecution. It is not merely physical restraint but a legal process with specific requirements and limitations defined under law.

Legal Definition: Under Section 2(a) of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, "arrest" means taking a person into custody under the authority of law. This action must be carried out in accordance with specific legal provisions and constitutional safeguards.

The power of arrest is not absolute. It is circumscribed by constitutional protections under Articles 21 and 22 of the Constitution of India, which guarantee the right to life, personal liberty, and protection against arbitrary arrest. The Supreme Court has repeatedly emphasized that arrest should be the exception, not the rule, and should be used only when absolutely necessary.

When Can Police Arrest You? Legal Grounds for Arrest

1. Cognizable Offences (Arrest Without Warrant)

Police have the power to arrest without a warrant for cognizable offences. These are serious offences where immediate action is required and police investigation can begin without magistrate permission.

Arrest Without Warrant in Cognizable Cases

A police officer may, without an order from a Magistrate and without a warrant, arrest any person:

Under the Bharatiya Nyaya Sanhita (BNS), 2023, cognizable offences include:

2. Cyber Crimes Under IT Act, 2000

The Information Technology Act, 2000, as amended in 2008 and 2021, defines several cyber offences where police can arrest without warrant:

Serious Cyber Crimes Allowing Arrest:

⚠️ Important Note on Section 66A: The infamous Section 66A of the IT Act (sending offensive messages through communication service) was struck down by the Supreme Court in 2015 in the landmark case of Shreya Singhal v. Union of India as being unconstitutional and violative of freedom of speech. However, many police officers are still unaware of this judgment and continue to arrest people under this non-existent provision. If arrested under Section 66A, immediately inform your lawyer as this is an illegal arrest.

3. Non-Cognizable Offences (Arrest Only With Warrant)

For non-cognizable offences, police cannot arrest without obtaining a warrant from a Magistrate. These are generally less serious offences.

Section 36 BNSS, Arrest for Non-Cognizable Offences

Police officers shall not arrest without warrant any person accused of a non-cognizable offence except:

Examples of non-cognizable offences include simple hurt, assault not causing grievous injury, defamation (in certain contexts), and public nuisance.

4. Special Circumstances for Arrest

Constitutional and Statutory Protections

1. Offences Punishable with Less Than 7 Years Imprisonment

Under Section 35(3) of BNSS, 2023, police officers shall not arrest a person for offences punishable with imprisonment for a term which may be less than seven years or which may extend to seven years with or without fine, UNLESS:

LANDMARK JUDGMENT: In Arnesh Kumar v. State of Bihar (2014), the Supreme Court held that arrest is not mandatory even for cognizable offenses, especially when punishment is less than 7 years. Police must justify the necessity of arrest and cannot make routine arrests.

2. Women Cannot Be Arrested After Sunset and Before Sunrise

Section 46(4) BNSS, 2023

No woman shall be arrested after sunset and before sunrise, except in exceptional circumstances by a woman police officer and with prior written permission from a First Class Magistrate. Even in such cases, the woman police officer must record detailed reasons for night arrest.

3. Arrest Restrictions for Specific Categories

Women

Cannot be arrested at night except with prior Magistrate permission and by woman officer

Section 46(4) BNSS

Persons Under 18 Years

Subject to Juvenile Justice Act provisions; special procedures apply

Sick or Infirm Persons

Section 55 BNSS

Members of Parliament/State Legislature

Speaker/Chairman must be informed within 24 hours of arrest during session

Article 22(2), Constitution

4. Economic Offences and White-Collar Crimes

For many economic offences, stringent conditions apply before arrest. The Supreme Court has mandated that in cases of cheque bouncing, dishonor of cheques, and similar economic offenses, arrest should be a last resort and only after thorough investigation establishing prima facie case.

5. Offenses Under Companies Act and GST Act

Several provisions in the Companies Act, 2013, and GST laws are non-cognizable or require prior permission/sanction before arrest, particularly for technical or procedural violations.

Procedure of Arrest: What Police Must Follow

Section 46(1) BNSS: The police officer making the arrest must inform you that you are being arrested and clearly communicate the grounds for arrest. This must be done in a language you understand. Silence or vague statements are insufficient.

If the arrest is being made under a warrant, the police must show you the warrant. You have the right to read the warrant and understand the charges against you.

Section 46(4) BNSS and Article 22(1): Police must inform you of your right to consult a lawyer of your choice immediately upon arrest. This is a fundamental constitutional right.

Section 54 BNSS: When arrested, you have the right to be examined by a registered medical practitioner at your request. If arrested by a woman officer or if you are a woman, examination must be by a female medical officer. Any injuries must be documented.

Section 46A BNSS: Police must inform a friend, relative, or person nominated by you about your arrest and the place of detention within 8-12 hours of arrest. This is mandatory.

Article 22(2) Constitution and Section 57 BNSS: You must be produced before a Magistrate within 24 hours of arrest (excluding journey time). Detention beyond this period without Magistrate's order is illegal.

Section 46(2) BNSS: Police must prepare an arrest memo at the time of arrest, countersigned by a witness (who may be a family member), and provide you with a copy. This memo contains details of arrest including date, time, and grounds.

Details of arrest must be entered in the station diary/general diary of the police station. This creates an official record.


Violation of Arrest Procedure: Any violation of these mandatory procedures can render the arrest illegal. You can challenge such arrest through habeas corpus petition before the High Court or Supreme Court, and police officers responsible can face departmental action and criminal prosecution.
