A shooting at a crowded New York club early Sunday morning left three people dead and eight wounded, authorities said.

Investigators believe a shooter or shooters opened fire with multiple weapons at Taste of the City Lounge in the Crown Heights neighborhood of Brooklyn, following a dispute just before 3:30 a.m. ET on Aug. 17, New York Police Department Commissioner Jessica Tisch told reporters.

“It’s a terrible shooting that occurred in the city of New York,” Tisch said at a press conference Sunday.

Officers are investigating at least 36 shell casings found at the lounge, including a firearm discovered on a nearby street, she said.

Tisch said the wounded in the shooting are being treated at hospitals for non-life-threatening injuries. The victims’ ages range from 27 to 61.

New York City is having a record low year for gun violence, the police commissioner noted.

“I mean, we have the lowest numbers of shooting incidents and shooting victims seven months into the year that we’ve seen on record in the city of New York,” Tisch said. “Something like this is, of course, thank God an anomaly, and it’s a terrible thing that happened this morning, but we’re going to investigate and get to the bottom of what went down.”
