SAN FRANCISCO - A 34-year-old man was shot on a Muni bus and San Francisco police are searching for the person who pulled the trigger.
He was taken to the hospital where he is expected to live, police said.
The shooting happened just before 6 p.m. Sunday in San Francisco on a bus at Mission and 13th Streets, according to police.
A witness on the bus said two men were arguing when he boarded and were "calling each other names" before the shooter allegedly challenged the victim to exit the bus and fight.
According to the witness, the victim got up from his seat and "got close to the door" when the suspect immediately shot him twice.
Police said they received a report that the suspect was wearing a brown and gold puffy jacket.
"We have worked diligently to improve Muni safety including increasing staff presence across our system and maintaining our network of cameras on each vehicle. If you see something, say something, and do not hesitate to call 911…Any questions about this specific incident should be directed to SFPD," SFMTA said in a statement.
Police also said no other passengers were injured.
It's unclear if the suspect and victim knew each other.
