Information on US terror suspect David Headley's links with several people in the country including Rahul, son of film maker Mahesh Bhatt, and some diplomats are expected to be shared by the FBI during the visit of its team to India later this week.
After handing over preliminary affidavits and some brief information, FBI had informed their Indian counterparts that further information would be made available only after further interrogation of US-born Headley and his Pakistani-Canadian accomplice Tahawwur Rana.
The Indian security agencies had sought all the details about Headley's links with Rahul, gym instructor Vilas Varak, some diplomats and business personalities who were allegedly misused by the terror suspect, sources privy to the investigations said on Monday.
The FBI arrested Headley and Rana from Chicago last month for allegedly plotting terror strikes in Denmark and India. However, Rana's advocate has denied the allegations made against his client.
The National Investigation Agency (NIA), probing the case, has already recorded statements of various people, including Varak, during which he told the investigators about various activities of Headley. The US terror suspect had changed his name to Headley in 2006 from Daood Gilani to avoid suspicion.
Indian investigators wanted to interrogate Headley and Rana and a team from New Delhi had gone to the US earlier this month. But the US did not give access because of the legal compulsions.
India, through various channels, had asked FBI some of the questions about Headley's association with Rahul Bhatt and somebusinessmen based in Mumbai.
The visit of the FBI team comes after a high-level meeting between Prime Minister Manmohan Singh and US President Barak Obama in Washington last week.
National Security Adviser M K Narayanan had said on Sunday that the US President had told the prime minister that he would be sending a high-level FBI team to India within a week with "all details".
