The National Investigation Agency arrested a suspected member of banned terror outfit Jamaat-ul-Mujahideen Bangladesh (JMB) from Sardarpara in Subhasgram, South 24-Parganas, on Tuesday.

Mohammad Abdul Mannan Bachu was arrested for his alleged role in online recruitment and radicalisation of youths for the terror outfit, senior officials of the NIA said.

A resident of Bangila Chadshi in Barisal, Bachu has been staying in Subhasgram posing as a businessman, NIA officers said. A passport, voter ID card and several other documents, all of which are fake, have been recovered from him, the officers said.

“One of his responsibilities was to create fake documents and ID cards for those who were sneaking into Bengal from across the Bangladesh border,” said a NIA official.
