From questioning on the street to detention at a police station, understanding the difference between police inquiry and arrest can help citizens protect their liberty and exercise their legal rights. A police officer asking questions, requesting identification or asking someone to accompany them to a police station can be an unsettling experience, particularly for someone unfamiliar with criminal law.
But knowing when a police inquiry becomes a restriction on personal liberty, what safeguards apply during an arrest and how to seek legal assistance can help citizens respond calmly and make informed decisions. In India, these protections are rooted in the Constitution and criminal procedure laws. 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 persons, including the right to be informed of the grounds of arrest, to consult a lawyer and to be produced before a Magistrate within 24 hours, excluding the time necessary for the journey. The first distinction to understand is between questioning, detention and arrest. Police questioning is part of an investigation and does not automatically mean that a person has been arrested.
Officers may ask questions, seek information or issue a lawful notice requiring someone to appear for questioning. A person receiving such a notice should read its terms carefully and comply with the applicable legal requirements. However, the circumstances matter. A person may be placed under police control even before officers formally describe the action as an arrest.
The National Legal Services Authority (NALSA), in its framework on access to justice before arrest and during remand, explains that custody and arrest are not always synonymous. The practical question is whether the person’s freedom of movement has been restricted and whether the police are exercising control over them. Detention is a broader term for holding or restricting a person’s liberty under legal authority.
Its legality depends on the circumstances and the power being exercised. Police cannot assume that they may keep someone at a station indefinitely simply because they want to ask further questions. Preventive action, questioning and formal arrest are governed by different legal requirements, and the label used by an officer does not, by itself, settle whether the action is lawful. Arrest, meanwhile, is a formal deprivation of liberty in connection with an alleged offence. It does not necessarily require a warrant in every case.
Under Section 35 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, police may arrest without a warrant in specified circumstances. For certain cognisable offences punishable with imprisonment of up to seven years, the law requires the officer to have reason to believe the person committed the offence and to be satisfied that arrest is necessary for specified purposes. The reasons for making the arrest must be recorded in writing.
Arrest is therefore not meant to be an automatic response to every complaint or suspicion. One of the most important safeguards concerns the grounds of arrest. Article 22(1) of the Constitution requires an arrested person to be informed of the reasons for the arrest. Section 47 of the BNSS also requires the officer making an arrest without a warrant to communicate the full particulars of the offence or other grounds for the arrest. In a judgment delivered on November 6, 2025, the Supreme Court reiterated that the grounds of arrest must be provided in writing and in a language the person can understand.
This requirement is intended to ensure that an arrested person understands why their liberty has been curtailed and can challenge the action if necessary. The law also recognises that an arrested person should not be cut off from the outside world. Section 36 of the BNSS requires the arresting officer to prepare an arrest memorandum, which must be attested by a witness and countersigned by the arrested person.
Under Section 48, the police must inform a relative, friend or another nominated person about the arrest and the place where the individual is being held. The arrested person must also be informed of this right. These safeguards help establish a record of the arrest and make it easier for family members to locate someone in custody. Access to legal assistance is another crucial protection.
Article 22 guarantees an arrested person the right to consult and be defended by a lawyer of their choice. Section 38 of the BNSS further provides that an arrested person may meet an advocate of their choice during interrogation, though not throughout the interrogation. The right to legal representation does not mean that police questioning must automatically stop whenever a lawyer is requested; rather, ask whether they are being questioned or arrested, why they are being asked to accompany the police and, if arrested, what the grounds are.
They should provide truthful information, avoid obstructing lawful police duties and request access to a lawyer when needed. If taken into custody, they can ask that a family member or trusted person be informed. Keeping a record of relevant details, where possible and lawful, may also help a lawyer assess whether the required procedures were followed. the law provides safeguards to ensure access to legal advice while permitting lawful investigation. People who cannot afford a lawyer may also seek free legal services.
Under Section 12 of the Legal Services Authorities Act, 1987, persons in custody are eligible for legal aid. Women, children, members of Scheduled Castes and Scheduled Tribes, persons with disabilities and other specified categories are also eligible, subject to the Act’s provisions. NALSA confirms that people called for questioning, as well as those arrested, can seek legal aid. Assistance is available through the District Legal Services Authority and other legal services institutions. Another important safeguard is the 24-hour rule.
Article 22(2) requires an arrested person to be produced before the nearest Magistrate within 24 hours of arrest, excluding the time necessary for the journey to court. Continued detention beyond this period requires the authority of a Magistrate. This does not mean that every arrested person must be released after 24 hours; a court may authorise further detention in accordance with the law. The rule ensures that police custody is subject to judicial oversight rather than being left entirely to the discretion of investigating officers.
For citizens, the practical response to a police encounter is equally important. A person may calmly These rights do not exempt anyone from a lawful investigation, nor do they prevent police from exercising powers granted by law. They establish boundaries within which those powers must operate. If a person believes their detention is unlawful, a lawyer can advise them on approaching the appropriate court, including through habeas corpus proceedings where applicable.
Ultimately, understanding the difference between questioning, detention and arrest is not about treating every police interaction as a confrontation. It is about recognising that police authority and individual liberty must coexist under the law. Knowing the grounds of arrest, the right to legal representation, the requirement of judicial oversight and the availability of free legal aid can help citizens navigate a difficult situation with greater clarity and confidence.
