A group of protesters left a trail of broken glass and paint tonight as they made their way from Dolores Park to Duboce on Valencia. Windows were broken, garbage cans overturned, paint bombs thrown, and messages saying “yuppies go home” as well as anarchist symbols were spray-painted on several restaurants, art galleries and cafes.
The façade of the police station on Mission and 17th was vandalized and broken.
A gathering at Dolores Park was advertised as a “a ruckus street party to counter gentrification, capitalism, and the policing of our communities.” About 200 attended, and chatted about their plans for the following day's May Day  activities while music played.
Shortly after 9pm, the group left the park and began to march on Dolores. Some overturned recycling bins and vandalized the windows at Farina restaurant minutes after turning the corner on 18th St, while others held back.
Dozens flocked to the sidewalk and began yelling, “this is not an Occupy SF action!” while passers-by looked on, concerned.
The group turned on Valencia, continuing to shrink in size and break windows. Within half an hour there were less than 50 people in the march.
About 40 of police on foot followed the march along Valencia, trailing behind as vandalism continued. SFPD representatives were not immediately available for comment, but based on witness accounts there were no arrests.
Neighborhood residents were angered and confused by the destruction. One man who did not wish to be named said, “They kept doing it while other people in the march were trying to get them to stop. It was childish.”
Occupy Oakland protester Jesse Smith told CBS  he was “more than a little shaken” by the events.
“I know Occupiers,” Smith told CBS. “None of us have any idea who they were.”
A message on the Occupy SF website  reads, “The march in the Mission Monday night was not an OccupySF event. OccupySF does not endorse this kind of destruction of the 99%’s property. The individuals involved in this destruction are not known to OccupySF, and we believe they are outside provocateurs sent in to tarnish the image of Occupy prior to the May Day actions.”
