A loud noise caused by a falling display case was mistaken for gunshots at Roosevelt Field mall, police said, causing a panic among shoppers on Christmas Eve.

Three people suffered minor leg injuries as they fled the Garden City mall, where Nassau County police responded at 1:16 p.m. to a call of shots fired, police said. Right after the incident, four helicopters hovered over the mall.

It was later determined that no shots had in fact been fired, a police official said.

Macy's security was taking a shoplifter into custody when the display case fell, making a loud noise that some mistook for gunshots, police said.

News 12 Long Island reported that customers started running and screaming because they thought shots had been fired.

Witnesses throughout the mall said officials directed them away from the Macy's area once shoppers began to flee.

The mall was closed for about 15 minutes and reopened after investigators determined no shots had been fired, police said. Holiday shoppers went back to searching for last-minute gifts.
