Two street vendors noticed the vehicle emitting smoke and alerted the police, which led to a massive response and the closing of Times Square while the bomb squad evaluated the vehicle. Officials described the bomb as being in the process of detonating, but it failed at some point, leaving the various explosives contained in the vehicle unexploded. The attempte bomber, Faisal Shahzad, was taken into custody two days later at JFK Airport as he attempted to board a flight to Dubai.
