NIA has said Fasih, one of the founding members of the banned outfit, was a resident of Darbhanga in Bihar while Anjum was from Nalanda in the state.
It has said that in and around November 2002, Yasin visited Darbhanga on the request of Fasih, who was deported from Saudi Arabia in 2012, and during his stay in Bihar, Yasin developed an “acquaintance” with Gowhar Azia Khomeni, another suspected IM operative.
The probe agency also said Yasin and other key operatives of the IM had also established safe hideouts in Darbhanga.
NIA, in its charge sheet, has named Yasin Bhatkal, his close associate Asadullah Akhtar, Manzer Imam and Ujjair Ahmed as accused for allegedly waging war against India, conspiracy for terrorist acts, membership of the terror organisation, radicalisation and recruitment of youths into IM.
Imam and Ahmed were arrested by NIA on October 1 and October 30 last year respectively on the basis of revelations and investigation done after the arrest of Bhatkal and Akhtar from Indo-Nepal border on the night of August 28 last year.
