The court was passing orders on a petition by CB-CID SID seeking seven days' custody of Kunhu Mohammed arrested on July 31 from Malappuram in Kerala.
He was wanted by the police in connection with the February 14, 1998 serial bomb blasts that had rocked the city claiming 58 lives.
When the CB-CID petition came up for hearing, Fifth Judicial Magistrate Selvakumar allowed three days' custody of the accused and directed the investigating agency to produce him on August 5.
