From the New York Times:
A suspicious vehicle in the heart of Times Square led the police to clear thousands of tourists and theatergoers from the area on a warm and busy Saturday evening.
Police officials said a witness reported a running Nissan Pathfinder with Connecticut plates, with smoke coming out of the back. A bomb squad robot popped the back latch of the Pathfinder, and officers found what they initially believed was a bomb. The vehicle was found to contain explosives, gasoline, propane and burned wires, a Fire Department officer told Reuters. The officer, who did not give his name because he was not authorized to speak to the news media, said that a man was seen fleeing the S.U.V. and that the police evacuated the area in case there were other threats nearby. Police were treating the vehicle as a “failed device” and were searching for a suspect.
