West Bengal Crime Investigation Department (CID) has arrested two persons in connection with the blast in Murshidabad's Nimtita Railway Station in which state minister Jakir Hossain and over 20 others were injured.
The two have been identified as Abu Samad and Sahidul Islam. The West Bengal CID is also conducting raids to arrest those involved in the case.
Earlier, the West Bengal CID had detained a Bangladeshi national in connection with the blast in
Murshidabad's Nimtita Railway Station in which Jakir Hossain was injured.
Hossain, Trinamool Congress MLA and the minister of state for labour, was waiting at platform number 2 to catch a train to Kolkata around 10 pm on February 17 when the blast occurred, seriously injuring him and the others.
"We have detained one person and investigation is underway," a senior CID official said.
