Eleven people were arrested late last night as police raided an off-campus fundraiser in support of Berkeley student protesters.

The fundraiser, a dance party held at the Exit 154 Gallery in San Francisco, was scheduled to begin at 10 pm. According to a first-person account I received via email, police and fire marshals arrived on the scene sometime after midnight, and an altercation followed.

The blog Occupy CA is reporting that there were eleven arrests and multiple injuries at the party, with four people held in custody overnight. They say that nine of the eleven are facing misdemeanor or felony charges.

Update | A student newspaper report on the incident describes a chaotic melee — cops brawling with partygoers while bystanders chanted “fuck the police.” The paper says that the party was organized by student activists from SFSU, UC Berkeley, UC Davis, and UC Santa Cruz, and that one of their reporters, a San Francisco State student, was arrested as she photographed the fracas.
