Kolkata, Oct 24 (IANS): NIA Director General Sharad Kumar Friday visited West Bengal to review the investigation into the Oct 2 blast in Burdwan in which militant group Jamaat-ul-Mujahideen Bangladesh is suspected to be involved.

The blast from an improvised explosive device (IED) in a rented house in Khagragarh killed two suspected militants and injured another.

Six people, including two women, have been arrested in connection with the case being probed by the National Investigation Agency (NIA).

Besides visiting the Khagragarh blast site, Sharad Kumar went to Murshidabad district's Beldanga, where one of the killed militants Shakil Gazi had a rented accommodation.

"I came here to review the investigation. I visited Burdwan and Murshidabad. I had detailed discussion with my officers to evolve strategies for the arrest of absconding persons," Sharad Kumar told mediapersons in Kolkata.

Investigators have been hunting for Kausar and Rezaul Karim from whose house in Burdwan, a cache of improvised bombs was recovered by a NIA team.

Beside the six arrested in Bengal, six others were held in Assam for their involvement in the incident. The agency is also probing the link between the Burdwan blast and a bank robbery in Telangana's Karimnagar.

NIA officials Thursday visited Choppadandi village in Karimnagar district where four armed men looted Rs.46 lakh from the State Bank of India in Feb this year.
