Police aren't sure what led up to a violent shooting outside a bar in Germantown tonight.

But it's results are clear: A 33-year-old man is clinging to life at Albert Einstein Medical Center after being shot three times in his side and arm.

The incident happened just before 10:30 p.m. on Wayne Avenue near Chelten, not far from Victor's Tavern, Chief Inspector Scott Small, who responded to the scene, said.

Officers from the 39th District took the man to Albert Einstein Medical Center, where he was listed in critical condition.

Witnesses told investigators that the man was shot by another man after he exited the bar. The victim then stumbled back into the tavern, where police found a trail of blood.

Those witnesses are being interviewed tonight by detectives from Northwest Division, Small said.

There's no information on a motive, and the suspect, who was recorded on nearby surveillance cameras, was last seen fleeing from the scene on Wayne Avenue.
