Kolkata: Two operatives of Jamaat-ul- Mujahideen Bangladesh (JMB) have been arrested from West Bengal's Murshidabad district and a cache of explosive materials seized from their possession, a senior police officer said Wednesday. In a joint operation by the Special Task Force (STF) of the Kolkata Police and the Murshidabad police, Moshibur Rahman (35) alias Farooque and Ruhul Amin alias Saifullah (26) were apprehended Tuesday night, he said.

"Both Moshibur and Ruhul, residents of Murshidabad district, are active members of the outlawed JMB. A cache of explosive materials, including aluminium dust, calether (spirit of ether) and sulphuric acid, have been recovered from their possession," the senior officer told PTI. The duo happen to be associates of Kauser and Sajjad, who were nabbed on January 29 for their involvement in 2014 Burdwan blast case, he said. On October 2, 2014, a blast had occurred in a house at Khagragarh in Burdwan district, killing two persons. "We have interrogated Sajjad and found out that Moshibur and Ruhul have been trained in making acid bombs. Their plan was to attack the police and get Kauser released," the officer said.
