Federal agents and police detectives arrested a man in connection with Saturday’s foiled Times Square attack early Tuesday: The Connecticut man, Faisal Shahzad, 30, is a naturalized American citizen who is originally from Pakistan. Officials took him into custody at JFK Airport, The New York Times reports. He was nabbed "at the last second," a source tells CNN—the flight he was on, headed to Dubai, had to return to the gate for authorities to make the arrest. Shahzad reportedly paid cash three weeks ago for the 1993 Nissan Pathfinder later found parked in Times Square and rigged with explosives; no paperwork was apparently involved in the sale. He also recently returned from a trip to Pakistan. Charges against Shahzad have not yet been announced. Cellphone tracking was instrumental to finding Shahzad, according to Politico. “They were able to basically get one phone number and by running it through a number of databases, figure out who they thought the guy was,” one official told Politico.
