Police: Man not involved in bus fight, tried to intervene

PITTSBURGH (AP) — Authorities in western Pennsylvania say a man reported earlier as having been responsible for a knife attack on a Pittsburgh bus was actually trying to intervene in a fight between two women, one of whom has been charged.

Police initially said a man attacked a woman with a knife on a Port Authority bus in the city's Point Breeze neighborhood just after 7:30 p.m. Saturday.

But after a review of surveillance footage, investigators say the man tried to intervene in a fight between two women, and one of them pulled a knife. The man fled and was apprehended a few blocks away, but police say based on the new evidence he will face no charges. The woman with the knife has been charged with aggravated assault.
