BRIDGEPORT - Federal officials now believe the Bridgeport man who tried unsuccessfully to set off a bomb in Times Square was working with the Pakistani Taliban.

If true, it would be the first time the Pakistani Taliban has tried an attack on the United States.

Authorities say Faisal Shahzad has been cooperating since he was arrested on board a plane about to leave for Dubai two days after the failed car bombing.
