India today indicated the possibility of gaining access to terror suspects David Coleman Headley and Tahawwur Rana, both arrested by FBI, once they are indicted by the US. Union Home Secretary G K Pillai told PTI that the investigations into the terror duo's Indian trails will take another 3-4 weeks. While Headley is a Pakistani-origin American national, Rana is a Pakistan-born Canadian citizen.<br/><br/>India is expected to get information about the plans and network of Headley and Rana next week when a high-level FBI team visits New Delhi with all details of their probe.<br/>
