In the four member team three officers will be of National Investigation Agency (NIA) and one will be a law officer who will travel to Chicago and are expected to interrogate Headley next week, official sources said.
The team is going to US after the assurance given by the US Justice Department that all concerned officials and the lawyer of Headley will be available during the visit of the Indian team to facilitate their access to Headley.
Still there is confusion regarding the availability of Headley for the number of hours needed to Interrogate him.
Headley, a Chicago-based American with roots in Pakistan, had already confessed to have hand in the planning of the ghastly attacks that killed 166 people in the country"s financial capital in November 2008.
After being arrested in October, 2009 the 49-year-old Headley entered a plea with the U.S. government in March this year, where he was offered to be available to foreign investigators through deposition, video conferencing or letters rogatory.
