Man with assault rifle arrested in Times Square subway station

An Ohio teen was busted with an AK-47 assault rifle and a gas mask inside a Times Square subway station Friday afternoon, law enforcement sources said.

The 18-year-old, whose identity was not immediately released, was taken into custody without incident at around 12:30 p.m. on the mezzanine level of the subway station off the A, C, and E line, the sources said.

Sources say the teen was sitting down and charging his cell phone inside the station with the weapon out next to him in plain sight when a uniformed transit cop spotted him.

The AK-47 was unloaded, but the teen had a fully loaded magazine in his backpack, along with the gas mask, according to the sources.

He told police that he thought carrying an unloaded rifle with the ammunition stored separately is legal in New York City, a high-ranking police source said.
