Kolkata: The Central Bureau of Investigation has appealed the Calcutta High Court on Monday to turn down the bail plea of Srinjoy Bose. Srinjoy got out from the jail on a bail plea on last Wednesday. It is believed that Bose got out of the jail due to the negligence of the CBI. According to sources, Srinjoy was not charged under IPC 409 section. Hence, he could get the bail.
