Faisal Shahzad, a Pakistani who was naturalized as an American citizen in 2009, was arrested late last night as he was about to escape to Dubai. He was on board an airplane at JFK and apparently came within a few minutes of getting away. No word yet on whether he acted alone or had associates either in the U.S. or abroad.
UPDATE: The New York Post says evidence of foreign involvement is strong:
An Obama administration official said earlier, “Don’t be surprised if you find a foreign nexus. They’re looking at some telltale signs, and they’re saying it’s pointing in that direction.” …
Forensic evidence gleaned from the SUV supported the theory of foreign terrorist involvement, officials said. A source said that evidence specifically involves one of the alarm clocks fashioned into a timing device on the propane-and-gasoline bomb.
