Customs and Border Protection agents working at the super-secret National Targeting Center discovered that Shahzad, who was by this point was on a no-fly list, had purchased a ticket and was on a flight manifest for a plane headed to Dubai, federal officials told ABC News. The agents contacted their CBP counterparts at JFK who then rushed to the plane and alerted the crew to their high-priority passenger.
The crew paged Shahzad via the plane's intercom to come to the front of the plane. Remarkably, Shahzad calmly complied, got up, retrieved his bag and ambled to the front of the plane. He was detained just outside the plane's doors.
CBP agents took Shahzad to a holding cell where the suspected terrorist informed them he had a car in an airport parking lot with a gun inside. Authorities surrounded the car, called in bomb sniffing dogs and cleared the scene.
