Investigators seek NY attack motive

No evidence has been found that Rahami received military training overseas

Investigators were searching on Tuesday for clues to the motive behind the bombings and attempted bombings in New York and New Jersey over the weekend and to determine whether the Afghanistan-born suspect had accomplices or was radicalized overseas.

Ahmad Khan Rahami, 28, was arrested on Monday in Linden, New Jersey, following a dramatic gunbattle with police after they were summoned by a neighborhood bar owner who thought the bearded man sleeping against his closed tavern's front door in the pouring rain resembled the bombing suspect.
