4 are shot, 1 critically outside a Brooklyn nightclub early in morn

Three men and a woman were shot — one critically — in gunfire outside a Brooklyn nightclub early Saturday, police said.

The violence erupted on Utica Ave. near E. 49th St. in East Flatbush about 3 a.m. when an argument inside the Island CZ Lounge spilled out to the sidewalk, cops said.

Bullets hit a man, 31, several times in his thigh, ankle and foot, cops said. He was listed in extremely critical condition at Kings County Hospital.

Also hit were a man, 36; a woman, 25, who was struck in the stomach, and another man, 38, who was hit in the shoulder and buttocks as he tried to run from the scene.

The three less seriously injured victims were also taken to Kings County and were expected to survive. The gunman fled, and was still at large later on Saturday.

It was not immediately clear what sparked the fight, and cops were scouring the area for video footage that might help identify the shooter.

Neighbors said they were surprised about the violence outside the lounge, which sells Jamaican-style seafood.

“It’s a nice place,” said one man walking by on his way to church. “I would buy food from there and leave. Nice people there.”

A woman who lives nearby said she heard the shots that sounded like “pop, pop, pop, pop, pop, pop” but thought the noises came from drivers of souped-up cars who race on the street.

She said there hadn’t been any problems since the restaurant opened about a year ago.

“It’s kind of quiet. You hear a little music, but you don’t hear no brawls, no fighting,” she said, adding: “You got to be careful everywhere.

“Somebody want to get in your face, don’t want to wear a mask, all kinds of ignorance. It’s very toxic now,” she said.
