Extended custodial detention authorization allows magistrates to order continued police custody subject to judicial oversight and bail safeguards. If an arrested person cannot be investigated within the initial twenty four hours, the investigating officer not below sub inspector must transmit diary entries to the nearest Magistrate and forward the accused. The Magistrate may, after considering bail status, authorise custodial detention in suitable custody for specified aggregate periods, record reasons for detention, require personal production (with limited audio visual exceptions), and send orders to the Chief Judicial Magistrate. Where no Magistrate is available, an Executive Magistrate may authorise short aggregate detention and must transmit records to a Judicial Magistrate.
