National Security Advisor Ajit Doval, accompanied by National Security Guard (NSG) chief J.N. Choudhury and National Investigation Agency (NIA) director general Sharad Kumar, met Chief Minister Mamata Banerjee, whose government had opposed an NIA probe into the blast before the union home ministry asked the central agency to intervene.
"We met the chief minister and discussed the issue with her and we are happy to say that the chief minister and the West Bengal government have assured that the Centre and the state will work together in unearthing the entire case and take all kinds of action to see that such cases are investigated properly and prevented in future," Prakash Mishra, special secretary for internal security in the union home ministry, told media persons after the meeting.
The delegation earlier visited the blast site in Burdwan's Khagragarh, where two Jamaat-ul-Mujahideen militants were killed and another injured.
Several people have been arrested in connection with this blast.
