Kolkata, Oct 11 (IANS): The NIA, which is probing the Oct 2 explosion in Burdwan, Saturday approached a West Bengal court seeking the custody of the accused arrested in the case as well as transfer of the case to a Kolkata court, an official said.

Earlier, the West Bengal CID had been probing the blast that occurred in a house in Khagragarh in Burdwan killing two suspected Jamaat-ul-Mujahideen militants and injuring another. Four people including two women have been arrested in this connection.
