In India, the law does not set a fixed timeframe for the police to freeze a bank account; it depends on the reason for the freeze and the stage of the investigation.

Why can the police freeze an account?: Under the Code of Criminal Procedure (CrPC) and various special laws (such as the Prevention of Money Laundering Act or the Income Tax laws), the police or other authorities can order a bank to freeze an account if they believe it contains money linked to a crime.

Duration: The account remains frozen until the investigation or prosecution is completed, unless a court orders its unfreezing sooner. This could mean weeks, months, or even years in complex cases.

Your rights: You can contact the investigating officer, senior police officers, or the court to request unfreezing, especially if you can prove the money is not related to any illegal activity.

Court Orders: In most cases, the freeze must be supported by a written order, and the bank is required to strictly comply with it.

In short, the police can keep your account frozen as long as legally necessary for the case, but you can challenge it in court to release it sooner.
