US has to agree to Headley's interrogation by us: Moily

India has insisted that US must provide a direct access to its investigators to interrogate Pakistani-American David Headley, who has confessed to plotting the Mumbai terror attacks.

"...One day or the other, (the) US will have to agree and expedite the issue that Headley will have to undergo interrogation by our agencies", Union Law Minister M Veerappa Moily told journalists on Wednesday, a day after Washington said no decision has been taken to this effect.

Asked if the US denying access to Indian investigators is "unfair" and "unjustified" as the Indian government had allowed the Federal Bureau of Investigation to interrogate gunman Ajmal Kasab in Mumbai, he said "we don't want to pass a value judgment on their policy and matter".

But Moily added, "But this is a matter we need to hard press our argument and you know we have a strong bargaining and tell them (the US) what's necessary... We have to make a strong case, which we have already made out. Here (Mumbai attacks) he (Headley) is involved, he is really involved".

Four days after US Assistant Secretary of State for South Asia Robert Blake publicly stated in Delhi that Indian investigators would have an access to Headley, US Ambassador Timothy J Roemer in a statement yesterday said "no decision on direct access for India to David Headley has been made."
