Kolkata, Nov 11 (ANI): A small explosion occurred near the office of National Investigation Agency (NIA) in Kolkata, police and interior office officials said. An officer at the police control room in Kolkata said the cause of the blast at the NIA office had not yet been established. Interior ministry official said preliminary information was that nobody had been injured. The NIA is currently investigating an earlier explosion in Burdwan, near Kolkata in October, that the agency believes was a botched plot by Bangladeshi Islamist militants to kill Bangladesh's Prime Minister Sheikh Hasina. A Kolkata court on Sunday gave the NIA custody of Jamaat-ul-Mujahideen Bangladesh (JMB) commander Sajid, a Bangladeshi national who West Bengal police arrested on Saturday in connection with the blast. Sajid's arrest followed the detention of another suspect on Thursday.
