The manhunt is on: Police are seeking a white man who appears to be in his 40s after he was recorded walking away from a vehicle containing a car-bomb in Times Square. In the surveillance footage, he is seen removing his shirt as he walks away from the SUV. Meanwhile, ABC News reports that the bomber made several mistakes that probably explain why the vehicle failed to explode: For starters, he used a non-explosive kind of fertilizer. He also did not open the valves on the propane tanks. Police have interviewed the registered owner of the SUV used in the homemade car bomb, but have not provided any additional details.
