Can Delhi Police seize your mobile phone during a cybercrime investigation? Know your legal rights, BNSS provisions and how to get your seized phone back.

Your phone holds your bank apps, photographs, chats, work emails and often your whole life. So when a police team arrives during a cyber crime investigation in Delhi and asks for it, the first reaction is fear. Can they really take it? For how long? Can they read everything on it?

As advocates, this is one of the most common questions we hear. The short version is that the law allows the police to seize a mobile phone during an investigation, but only in a particular way and with limits. This blog explains your phone seizure rights, what the police must do, and how to protect yourself in practice.

Yes, the police can seize your mobile phone if it is suspected to be linked to an offence, for example a cheating, hacking, obscene content or online harassment case. A phone can be seized from a victim, a witness or an accused person.

But seizure is not a free pass:

• It must follow the procedure laid down in the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS).
• It must be recorded properly, with a seizure memo and, in most cases, audio-video recording.
• Taking the device does not automatically allow the police to read, copy or misuse everything on it.
• You keep your constitutional protections, including the right against self-incrimination and the right to privacy.

In July 2026 the Bombay High Court held that police had violated the BNSS safeguards when they entered a woman’s room and took her phone for two days without a seizure memo, and it awarded her compensation. The case shows that courts take the procedure seriously, although it is not binding in Delhi.

The Law Behind Phone Seizure

The provisions that matter most in a cyber crime investigation in Delhi are these. Section numbers are from the BNSS, which replaced the old Code of Criminal Procedure.

Provision	What it says in simple terms
BNSS Section 106	A police officer can seize property that is suspected to be stolen or is found in circumstances creating suspicion of an offence. A phone can fall here
BNSS Section 94	The police or court can issue a written order to produce a document or thing needed for the investigation
BNSS Section 185	A police officer can search without a warrant in certain situations, but must record reasons and follow safeguards
BNSS Section 105	Search and seizure should be recorded through audio-video means, preferably by mobile phone, and the recording sent to the Magistrate
BNSS Section 176	Forensic examination of evidence in serious offences, which is why phones are often sent to a forensic laboratory
BNSS Section 497	The Magistrate’s power to release seized property on interim custody
BNSS Section 528	The High Court’s inherent powers, used to challenge illegal seizure or refusal to release
Bharatiya Sakshya Adhiniyam, Section 63	Conditions and certificate for admitting electronic records as evidence, including hash value details
IT Act, 2000	Defines computer resource and electronic records, and gives powers of investigation in cyber offences
Article 20(3) and Article 21	Protection against self-incrimination and the right to privacy

Your Rights When the Police Seize Your Phone

Your phone seizure rights begin the moment the police ask for the device. You are entitled to expect the following:

• A seizure memo: A written record listing the phone’s make, model, IMEI and condition, signed by the police and, ideally, independent witnesses. Ask for a copy on the spot.
• Audio-video recording: The search and seizure should be recorded, as the BNSS requires.
• Identity and authority: Ask for the officer’s name, rank and the case or FIR number, and for the written notice or order if one exists.
• Female officer where needed: A search of a woman’s person or room should involve a woman police officer.
• Hash value and copy: Courts and forensic practice expect a hash value (a digital fingerprint) to be taken, so that tampering can be detected later. Ask that the phone is sealed and the hash is noted.
• SIM and accessories: Only what is relevant should be taken. Ask for a list of everything taken.
• A lawyer: You can have an advocate with you while the memo is prepared.
• A receipt and a reason: You can ask the grounds for seizure and which offence the phone is said to be connected with.

These safeguards also protect the police case. Evidence taken without proper procedure becomes easier to challenge in court.

Passwords, Fingerprints, Cloud Accounts and Private Data

This is the area where people are most confused, and where the law is still developing.

Can the police force you to give your password? There is no single settled answer from the Supreme Court yet. High Courts have taken different views. Some have held that compelling a password or biometric does not violate the right against self-incrimination, while other courts, including a Delhi sessions court, have held that an accused cannot be forced to disclose a password under Article 20(3). A petition asking the Supreme Court for guidelines on seizure of digital devices has been pending for some time. Until the law is settled, take legal advice before you decide, and do not give in to threats or pressure.

Fingerprint or face unlock: Some courts have treated these differently from a spoken password, as they are physical samples. Do not assume that this protects you, and take advice at once if you are asked to unlock the phone.

Cloud accounts and other devices: A seizure order for the phone does not by itself give the police the right to log in to your email, banking or cloud accounts. Access to those usually needs separate lawful steps.

Unrelated personal data: Photographs, chats and documents that have no link to the offence should not be pried into or leaked. If private material is misused, you can complain to the Magistrate and, where needed, approach the High Court.

Professional and privileged data: An advocate’s client communication, a doctor’s records or a journalist’s sources carry added protection. Tell the police at once if the phone holds such material.

What to Do If the Police Come for Your Phone

Stay calm and polite. Resisting or arguing with the police can only hurt you. Instead:

1. Do not obstruct, delete or reset anything. Wiping the phone now can create a fresh problem for you.
2. Ask for identity and papers. Note the officer’s name, rank, police station and FIR number, and ask for any written notice or order.
3. Call your advocate and put them on the line or ask the police to wait for them.
4. Insist on a seizure memo with the phone’s details, IMEI, SIM number and condition, signed by independent witnesses, and take a copy or a photograph.
5. Ask that the phone is sealed and that the hash value is noted.
6. Record the proceedings yourself if you can do so without interfering, or ask that the police video-record them as the law requires.
7. Note what was taken: phone, SIM, memory card, charger, other devices.
8. Do not sign blank papers or any statement you have not read.
9. Do not give your password or unlock the phone without legal advice.
10. Write down the details as soon as the police leave: time, names, what was said and taken.

If the phone belongs to your employer or contains client data, inform them in writing at once.

Getting Your Phone Back

A seized phone does not have to stay with the police for the whole case. Your options are:

• Ask the investigating officer in writing for return after the forensic copy has been taken, explaining why you need the phone for work, study or family.
• Apply to the Magistrate under Section 497 of the BNSS for interim custody (supurdnama) of the phone. Courts usually look at who owns the phone, whether it is still needed as evidence, and whether conditions such as a bond, an undertaking to produce it when asked, or preserving the data can protect the investigation.
• Offer a mirror image or clone. If the police need the data, ask that a forensic copy is made so the original can be returned. Courts often prefer a balanced approach.
• Move the High Court under Section 528 of the BNSS if the application is refused without proper reasons or the phone is kept for an unreasonable time.

Forensic laboratories can take months, so apply early. Courts have repeatedly said that seized property should not be left to rot in a police station, and orders refusing release should give reasons. Keep your purchase bill, IMEI box or telecom proof ready to prove ownership.

If the Seizure Was Illegal

If the police skipped the procedure, you are not without remedy. Depending on the facts, your advocate can:

• Send a written complaint to the senior police officer of the district, with the details of what went wrong.
• Apply to the Magistrate to report the seizure, to direct proper compliance, and to order return of the phone.
• Petition the Delhi High Court under Section 528 of the BNSS or under Article 226 of the Constitution against an illegal search, a seizure without a memo, or misuse of private data.
• Seek compensation in a fit case. Courts in India have awarded compensation for privacy violations during illegal search and seizure.
• Challenge the evidence at trial if procedure, hash value, chain of custody or the certificate under Section 63 of the Bharatiya Sakshya Adhiniyam was not properly followed.

A defect in procedure does not always end the case, because courts also weigh the evidence itself. But it can weaken the police case, support bail, and help you get the phone back.

Common Mistakes and Questions

A cyber advocate in Delhi often sees people make these mistakes during a phone seizure:

• Deleting chats, apps or files when the police arrive, which can look like destroying evidence.
• Handing over the phone and password casually without a memo.
• Signing blank or unread papers.
• Not noting the IMEI and SIM details, so that the phone cannot be easily identified later.
• Waiting months before asking for the phone back.

Can the police seize my phone without a warrant? In certain situations, yes, under the BNSS, but they must record reasons, follow the procedure and prepare a seizure memo.

Can they take a phone from a victim or witness? Yes, if it holds evidence. A complainant’s phone is often taken in cyber fraud and harassment cases. A complainant also has the right to a memo and to apply for return.

Do I have to give my password? The law is unsettled and courts have differed. Take legal advice before you answer and do not speak under pressure.

How long can the police keep my phone? There is no fixed period. The phone should not be kept longer than the investigation needs, and you can apply to the Magistrate for interim custody.

Can the police read my WhatsApp chats? They may examine the phone for material connected to the case through a forensic process, but they cannot misuse unrelated private data.
