The Pittsburgh police released a statement on the alleged incident, via Bob Hazen of WTAE-TV:
At approximately 9:30 p.m., security guards at The Flats on Carson summoned a Pittsburgh Police Officer who was working at a nearby restaurant due to an unruly customer who was in the process of assaulting the doorman. Once he arrived on the scene, the Officer stopped the assault and arrested the actor, identified as 39-year-old Pittsburgh Steelers assistant coach Joey Porter. Porter was taken to the Allegheny County Jail. His charges include aggravated assault, simple assault, public drunkenness and terroristic threats.
On Wednesday, the Associated Press (via Fox Sports) provided additional insight into the situation:
Review board executive director Elizabeth Pittinger says the ‘high visibility’ of the incident prompted the review, even though the board typically doesn’t investigate unless someone complains about police misconduct. Porter’s attorney says they didn’t file a complaint
