A bus driver in Tennessee displayed “call 911” on the front of the bus after a passenger attacked another passenger.

The Nashville Police Department received a call from a woman who saw the message on the WeGo Public Transit bus. Cops caught up with the bus at the next stop and interviewed the victim, who told police she got on the bus and sat down when a suspect, later identified as 40-year-old Augustine Collier, came up from behind her and grabbed her right hand, which was holding a phone.

She said Collier “continued to say racial comments to her and asked her why she was taking photos of him,” an arrest affidavit reviewed by Law&Crime says. As the two were scuffling, the bus driver slammed the brakes, causing Collier to fall onto the ground. Other passengers broke the two up until police arrived.
