PHILADELPHIA (CBS) — A 31-year-old man is critical condition, shot multiple times, after Philadelphia police say he pointed a gun at officers.

It all unfolded around 3 o’clock this morning. A 31-year-old man, police say, fired a gun inside the lobby, or right outside the lobby of the Philadelphia Housing Authorities Norman Blumberg Apartments, near 23rd and Jefferson.

Two housing police officers, along with a Philadelphia police officer and a FBI agent who responded to the call for back-up, caught up with the suspect in a vacant lot along the 2400 block of Stewart Street.

That’s when Chief Inspector Scott Small says the suspect pointed his gun at the officers, and possibly fired a shot.

“The officers returned fire, striking the suspect four times. He was struck in both shoulders, his stomach and his leg. He collapsed and he dropped his weapon. His weapon is a silver, semi-automatic hand-gun,” Small says.

Small also says they need to look for a shell casing in the snow to determine if the suspect did fire a shot at the officers.

No police were injured.

Meanwhile, the suspect is at Hahnemann University Hospital in critical condition. Small says he was positively ID’d by a witness as the man who fired the shot in the lobby of the homes. The suspect is also reportedly a person of interest in another weekend shooting.

Police are looking for another man seen running with the suspect before he was shot, but they don’t know yet if or how that person was involved.

The shooting is being investigated by public affairs, Central Detectives and the FBI.
