NEW YORK, N.Y.- Authorities in New York are still trying to determine exactly what kind of device was used to blow a gaping hole in the front window of an empty military recruiting station in Times Square.
The explosion shattered a glass door and window causing minor damage and no injuries. The center is normally staffed by two noncommissioned officers, but was empty at the time.
Police say they found a found a metal ammunition box that is believed to have contained the explosive and it is being sent for testing. Police also say the box is readily available in Army-Navy surplus stores.
The facility has been the occasional focus of antiwar protests and the commander of Army recruiting operations in Manhattan says if the blast was directed toward American troops then, in his words, "It's something that's taken very seriously and is pretty unfortunate."
Authorities say a witness saw a person on a bicycle wearing a backpack and a hood and acting suspiciously, but no one saw the device being placed in front of the recruiting center.
Guests at a nearby hotel say they heard a "big bang" and could feel the building shake.
