An undertrial inmate Ashim Das, was released from Bishalgarh Correctional Centre (Central Jail), in an act of oversight, last week and later taken back into custody when officials became aware that he was an accused in another case. Jailor Banikanta Debbarma said that Das was booked under charges of theft and was in custody at Bishalgarh Correctional Centre. He was released on September 15 along with four other inmates after authorities issued release orders. Das was undertrial for two cases before the court of Additional Chief Judicial Magistrate. He said that Das was immediately had him taken back to custody as soon as they realised that realised he was an accused in a second case also. The Agartala Police Court duty officer said that Ashim was released on bail on September 19 for the second case. However, he will have to report to the police periodically. The oversight occurred due to fewer officers and a low staff strength, said the Jailor . Bishalgarh Correctional Centre has 477 inmates including 31 women.
