Gunfire erupts at skating rink in New York City

(CNN) -- New York City police detained a 16-year-old boy Sunday in connection with a shooting at the Bryant Park skating rink that wounded two people.

Police believe the shooting Saturday night began over an argument about a coat, according to New York Police Detective Kelly Ort.

One victim was shot in the back and the second one in the leg, police said. The victims' injuries are not life-threatening.

Megan Cutcher, a San Francisco resident visiting New York City, was having a drink with relatives at a nearby restaurant when the gunfire started.

"We sat down at one of the outdoor couches with a heater and ordered a drink," Cutcher said. "Right after we ordered, we heard three shots. Initially, it just sounded like a pop gun, but then people started screaming, and we realized it was more serious."

She grabbed her mother and pushed her under the table.

"We were at most 10-15 feet from the ice," she said. "Luckily, the couches we'd been sitting on blocked us from the view of the shooter."

A few minutes later, the gunfire stopped and the restaurant staff ushered them into the kitchen for safety.

"I was able to calm down a bit, though my heart was racing," she said.

Police ordered them to stay put while they searched the area. About an hour later, they got an all-clear to use a particular exit.
