<br/>India will soon be writing to the US Department of Justice seeking a date for having direct access to Mumbai terror attack suspect David Headley, currently under US custody. The National Investigation Agency, NIA, will file the charge sheet against him in a court in India only after getting direct access to him. The decision comes close on the heels of Government stating that it was not taking cognisance of the clarification issued by the US Ambassador to India Timothy J Roemer that no decision has been taken and the US has yet to work out how India would be given access. AIR correspondent says investigators believe that access to Headley can be obtained only through legal channels as he is under court's custody.
