Kingston, N.Y. ? A lone gunman opened fire with an assault rifle Sunday inside a crowded mall in upstate New York, wounding one person before running out of ammunition and being subdued by employees, authorities said.

The gunman began shooting inside the Hudson Valley Mall shortly after 3 p.m. in Kingston, nearly 90 miles north of New York City.

The 24-year-old gunman went into a Best Buy store and started firing. When he ran out of ammunition, he was captured by mall employees, police said.

Police did not identify the suspect. Capt. Wayne Olson said investigators did not know the exact number of shots fired.

An Army recruiter was shot in the leg but was not the target of the attack, said Lt. Col. Paul Fanning, a National Guard spokesman. The recruiter was evacuated by helicopter to an Albany hospital, where he was listed in critical condition.

Another person was injured in the hand, but police said the injury was not a gunshot wound.

Ulster Town Supervisor Fred Wadnola identified the gunman’s weapon as an AK-47 assault rifle.

“Everyone was running and screaming. Then I heard the shots,” witness Heather Craig told Fox News. “People were running over people. Other people were just standing there dumbfounded.”

Louis Savva, of Kingston, N.Y., is shown near the Hudson Valley Mall in Kingston, after a shooting inside the mall. A lone gunman opened fire with an assault rifle inside the crowded mall in upstate New York on Sunday. Savva heard about the shooting at the mall and came looking for his daughter, Barbara. She was safe.

Ali Afshar, owner of a mall kiosk, said he saw the gunman being tackled from behind by two men who worked at a sporting goods store. Afshar said the gunman was dressed in black.

All mall entrances remained blocked off by police Sunday evening.

Michael Bovalino, chief executive officer of the mall’s parent company, said counselors would be available for mall employees today.
