A large group of protesters marched from Dolores Park shortly after 9 p.m. Monday night and vandalized parts of the Mission District, including the San Francisco Police Department's Mission station at 630 Valencia Street.
At least a dozen businesses, including Tartine Bakery at 18th and Guerrero streets and Locanda restaurant on Valencia, had their windows broken out and were splattered with paint and food. Vehicles along Valencia and Guerrero streets had windows broken out - an Aston Martin had its windshield shattered and brown paint covered the hood.
The report, which was filed at 11 p.m. last night, doesn't make clear whether these were self-identified May Day protesters, but big May Day rallies are set for that city today, too, leading to plans by San Francisco authorities "for nothing and for everything."
UPDATE: More from the San Francisco Bay Guardian, which connects the protesters to May Day but also features rejection of their tactics by the local Occupy movement.
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.”
SF Weekly connects the vandalism to May Day as well, saying "the chaos broke out shortly after 9 p.m. after occupiers marched from Dolores Park through the Mission District in preparation for today's May Day general strike."
