Passengers are tightly-packed aboard Muni and not always friendly.
A day after a video surfaced showing a two women fighting over a seat on a Muni bus, there's more proof that taking public transportation in the City can be dangerous to your health.
Wearing the wrong color shoes could have landed an 18-year-old actor in a hospital with broken bones and bruises in his face.
Christopher Borgzinner plays a street thug in the film "La Mission," set in San Francisco. He was riding the 9-San Bruno Muni bus to his acting class in the Mission on Monday when he met up with at least four of men who thought he really was part of a gang, the Chronicle reported. But San Francisco Police Department Deputy Chief of Investigations David Shinn said he believes the men may have used the gang symbol as an excuse to rob Borgzinner.
Borgzinner was wearing red shoes, the color claimed by the Norteno street gang. Shinn said police have video of the incident and while no arrests have been made, the tape shows four men attacking the young actor.
The real-life thugs stole Borgzinner's wallet and other posessions and beat him so badly, he suffered orbital bone fractures under both of his eyes, the paper reported.
It was not the first time Borgzinner was the victim of violence in the City. In January 2008, gang members attacked him at 16th and Mission streets while he was on the way to a poetry slam, according to the paper.
Shinn said police will increase the amount of uniformed and undercover officers that ride Muni in response to the two attacks. Anyone with information about Borgzinner's attackers is asked to call the anonymous tip line at 415-575-4444. The attackers face charges of felony assault with great bodily harm and robbery, according to Shinn.
