Khaleed alias Khalid Mohammed, who had been residing in Hyderabad on the basis of alleged fake documents, was arrested by the state police on November 16 following an intelligence tip-off by central security agencies, official sources said on Tuesday.
He was handed over to the NIA yesterday afternoon after security agencies felt that his role in Burdwan blast needed to be probed further, the sources said.
This is the seventh arrest made by NIA in connection with the Burdwan blast case of October two in which two persons died inside a house after the IED being manufactured by them went off accidentally.
Khaleed is believed be an expert in Improvised Explosive Device, the NIA said and claimed that he belonged to Rohingiya solidarity organisation and had links with Bangladesh-based terrorist groups.
The NIA also claimed that he was involved in running terror camps in bordering areas of Bangladesh and Myanmar.
A search at his residence led sleuths to his laptop which contained incriminating videos of training material, literature relating to various kinds of poison, IED-making, bomb-making, explosives and 'Jihadi' Literature including that relating to ISIS.
He was allegedly trained by Tehrik-i-Taliban.
