A man wearing a Pittsburgh Steelers jersey, face mask, a Pittsburgh Panthers hat and wearing what appears to be a Pittsburgh football helmet has been found on a Pittsborough team bus, police said.
Police said Monday that the driver of the team bus saw the man and alerted them.
The man was taken into custody and was booked into the Allegheny County Jail on charges of aggravated assault and resisting arrest, police spokesman Sgt. Brian Gann said.
The Pittsburgh Police Department also is assisting with the investigation.
The Steelers and Panthers will play on Sunday in Pittsburgh at 4 p.m.
The Pittsburgh Post-Gazette reported that a witness told police that the man had been on the team buses at the Pittsburgh airport, but that he was not on the bus when the incident occurred.
