PHILADELPHIA (CBS) — An altercation inside a bar in North Philadelphia quickly turned deadly overnight.

It happened just after 12:30 a.m. Saturday inside Mr. Chicken & Bernice’s Lounge along the 2000 block of Dennie Street in the Tioga-Nicetown section of the city.

Police say a fight inside the bar escalated to gunfire when someone pulled out a gun and shot a 24-year-old man in the back.

The victim was taken to Temple University Hospital where he was pronounced dead a short time later.

The gunman fled the scene, but police were looking at surveillance video to help identify the suspect.

“Fortunately, there’s a camera system inside of this bar,” said Chief Inspector Scott Small. “Hopefully those cameras recorded something that could help us with this homicide investigation.”

Authorities were also questioning patrons and employees who were inside the bar at the time and witnessed the shooting.

The victim’s identity was not immediately released.
