Gregory Graniss, 22, was also charged with destroying a passenger transit vehicle -- the 8X-Bayshore Express bus that he allegedly targeted during the revelry early on Oct. 29 after the Giants swept the Detroit Tigers to win the World Series.
A San Francisco Chronicle photographer captured a picture of a man smashing the windshield of the bus with a metal police barricade during the raucous celebration.
The image was circulated widely, and social media users helped identify Graniss as the suspect. He turned himself in to police on Tuesday.
Graniss is out of custody on $40,000 bail and spoke briefly during his arraignment this afternoon to agree to waive his right to a speedy preliminary hearing.
His attorney, Douglas Rappaport, said outside of court that Graniss is taking responsibility for the vandalism and asking for forgiveness from San Franciscans.
"The Giants' victory was amazing and it really brought out the best in San Francisco, and unfortunately the worst in Gregory," Rappaport said. "He is very ashamed of his actions and very, very sorry."
Assistant District Attorney Lindsay Hoopes said prosecutors may decide to file additional charges against Graniss at a later date because of the passengers on the bus who were endangered.
Eight passengers and the bus driver got off the bus safely before other vandals lit it on fire, destroying it.
Police have not yet arrested the suspects responsible for the arson but released a video last week that was recorded by a bystander showing two suspects lighting the bus on fire. The video is available online at www.vimeo.com/52506635.
District Attorney George Gascon is planning a news conference later this afternoon to discuss the case.
