Under the Bharatiya Nagarik Suraksha Sanhita, 2023, a person who is arrested without warrant and is in custody because of a cognizable/relevant offence must, ordinarily, be produced before the nearest Magistrate within:

The BNSS requires that a person arrested without warrant be produced before the nearest Judicial Magistrate or Executive Magistrate, as the case may be, within TWENTY-FOUR HOURS of the arrest, EXCLUSIVE of the time necessary for the journey from the place of arrest to the court of the magistrate. This production requirement is a constitutional safeguard under Article 22(2) and a key check on arbitrary and indefinite detention. Delay beyond the prescribed period vitiates the remand. The 24-hour rule anchors the custody-review process in the BNSS.
