Oh dear, here we go: San Francisco police have declared the OccupySF takeover of a vacant building at 888 Turk (at Gough) a "crime scene," and have raided the building, according to KGO. Supporters are now outside the building chanting "Long live the SF Commune!" while police surround the building.

As part of the nationwide "We Won't Get Fooled Again" Day of Action on Sunday, OccupySF reclaimed 888 Turk, rechristening it OccupySF Commune with plans to turn it into a food bank and social center. The group says the building is owned by the Archdiocese of San Francisco and has been vacant for five years.

Watch the action, care of EyeofRah, below:
