Two suspected terrorists of the Jamaat - ul - Mujahideen Bangladesh (JMB) were arrested from West Bengal on Tuesday in connection with the Burdwan blast in which two suspected terrorists of the outfit were killed and another was injured, the NIA said.
Habibul Hoque, 30, and Enamul Molla, 25 - - both residents of North and South 24 Parganas, respectively - - were arrested for having close association with the accused arrested and absconding in the blast, an official said.
The blast took place on October 2, 2014 in a two - storeyed building in Khagragarh locality of Burdwan.
Police seized 55 improvised explosive devices and some other explosives along with wristwatch dials and some mobile SIM cards.
