John Slaviero was arrested after the incident, which occurred around 6:16 p.m. on Thursday, November 5, near Columbus Avenue and Union Street. According to the DA's office, the victim told investigators he was riding the bus when Slaviero pushed him while attempting to exit. The victim said he pushed back, and the two exchanged words.

Slaviero then allegedly got off the bus, retrieved a firearm, and fired two shots back into the vehicle. A bystander tackled him and held him on the ground until police arrived, while the victim disarmed him, authorities said.

"Two bullet holes were found above the seat the victim was attempting to occupy," the DA's office said in a release. "At the time, the victim and numerous passengers were inside the bus, including children."

Slaviero has been charged with assault with a firearm, assault with a deadly weapon committed against a public transit employee or passenger, discharge of a firearm at an occupied motor vehicle, possession of a deadly weapon (metal knuckles), and carrying a loaded firearm.

The shooting marks the third violent incident on a Muni bus in the past six weeks. Late last month, a man was stabbed after a confrontation with another passenger on a 5-Fulton Owl bus in the Western Addition. In late September, a person who intervened to stop a suspect from harassing a woman on a bus in SoMa was stabbed in the neck.

Despite the arrest, San Francisco police are asking anyone with information about last week's shooting to call the department's tip line at 415-575-4444 or text a tip to TIP411 beginning with "SFPD." Tipsters may remain anonymous.
