Momin, who has been on the run since last year, was apprehended from Sealdah in central Kolkata on Saturday evening.
The blast in Burdwan took place inside a house on October two last year, leaving two persons dead. The NIA took over the case from West Bengal police a few days after the explosion after international links surfaced.
Investigators have found that Improvised Explosive Devices were being fabricated in the house and later smugged to neighbouring Bangladesh. The NIA has so far found that members of JMB terror group had established their network in different places such as Murshidabad, Nadia, Malda, Birbhum, Burdwan in West Bengal and Barpeta in Assam, Sahibganj and Pakur in Jharkhand.
The NIA also claimed that senior members of JMB had established terrorist training centres and bomb-making units in Beldanga and Mukim Nagar of Murshidabad, Nanur of Birbhum and Khagragarh and Simulia of Burdwan district.
