Pakistan-based terror group Lashkar-e-Taiba (LeT), blamed for the 26/11 Mumbai terrorist attack, was planning to use an American national to carry out another major terrorist attack in India, the FBI said on Tuesday.

The man, identified as David Coleman Headley, was arrested early this month by the Federal Bureau of Investigation's (FBI) Joint Terrorism Task Force at O'Hare International Airport before boarding a flight to Philadelphia, intending to travel on to Pakistan.
