The victim, a 21-year-old white man, was transported to UPMC Presbyterian Hospital in stable condition and underwent surgery to repair any damage, according to an e-mail from city police spokeswoman Diane Richard.

The actor, described as a 5-foot-8 white man wearing a black coat and stocking cap, was not apprehended at the scene.

Richard said that the victim was sitting at the bar when someone bumped into him. An argument broke out and the two began pushing one another. It was then, the victim told police, that he was stabbed.

No witnesses reported seeing a knife.

A witness told police that the actor fled upstairs in the bar, but that he lost sight of the actor in the crowd. Richard said that the surveillance cameras were not recording at the time.
