Officers of Federal Bureau of Investigation (FBI) interrogated IS agent Masiuddin alias Musa in the office of the National Investigation Agency (NIA) at Salt Lake on Thursday.
This is the second time in the city’s history when a team comprising FBI’s officer came to the city.
Earlier, a team of FBI officers visited the city in 2002 after the American Centre attack.
Sources said that the FBI officers came to interrogate him after knowing that he was involved with
Gulsan attack in Bangladesh and was in regular contact with the top IS leaders including Safi Arma.
Even his call records suggested that he had voice calls with some people in Syria and Afganistan, though he used to be in touch with Safi Arma through web-chats and social networking sites.
Musa (25) was arrested from Burdwan Station in Viswa Bharati Fast Passenger on July 5 by the Criminal Investigation Department (CID). Later, NIA officers took him in their custody and he was interrogated.
He was in judicial custody. He was remanded in the custody of the NIA for two days when produced before the Bankshall Court on Thursday.
He was taken to the NIA’s office where FBI officers questioned him about his link with his counterparts in Syria and what they had planned to execute after Gulsan attack which got foiled following his arrest.
It was learnt that the FBI officers had information about his meeting with a top IS leader in a neighbouring country and the reason behind his stay in Tamil Nadu for a long time, leaving his family at Registry Para at Labhpur in Birbhum.
The FBI officers wanted to know how the IS activists are attracting more youth to join the outfit.
Sources said Musa told the FBI officers that there had been a constant effort to develop hatred
among IS activists against white people.
