Mumbai attack terrorist David Headley, who is currently in American custody, has been opposing his further interrogation by Indian investigators.
This was conveyed by Washington to New Delhi during Indo-US strategic dialogue held here today, after India had persistently asked the US to give access to Headley for a second time to get more information about the November 2008 audacious attack.
Indian investigators had questioned Headley in 2010.
The US interlocutors have cited Headley's plea bargain with the American authorities (under which a person avoids death penalty by confessing to the crime) and indicated its difficulty in allowing Indian investigators to further question Headley who had carried out the recce of the 26/11 targets for the Pakistan-based terror outfit Lashkar-e-Taiba, official sources said.
However, India may be allowed to question Headley's accomplice Tahawwur Hussain Rana who helped his childhood friend to recce the 26/11 targets.
Indian investigators believe that if they could quiz Pakistani-Canadian Rana, many information could come to light as he was a close associate of his Pakistani-American friend Headley.
The investigators believe that Headley and Rana have a lot of information and their interrogations could throw more light on the conspiracy hatched to carry out the worst terror strike in India and role of those behind it.
Headley had pleaded guilty to 12 terrorism charges, including his involvement in the November 2008 terror attacks in Mumbai that claimed 166 lives. He had, however, entered into plea bargain with US authorities.
A court in the US had sentenced 52-year-old Rana to 14 years in jail followed by five years of supervised release.
Rana was convicted for providing material support to LeT and for backing a "dastardly" plot to attack a Danish newspaper but not convicted for the Mumbai terror attack despite being a close associate of Headley.
Later, Union Home Secretary R K Singh had a separate meeting with Deputy Assistant Attorney General Bruce Swartz and discussed various issues related to cooperation in anti-terror efforts.
Asked whether the US will give India access to Headley and Rana, Swartz said "we will continue to cooperate in Mumbai attack".
