The alleged owners showed up with the police, but the Oakland Police Department refused to get involved in an illegal eviction. Subsequently the "owners" kicked in the door and began destroying the house and everything in it while terrorizing the occupants.
The police returned and arrested one of the "owners" for disorderly conduct. This is a major victory for the Safehouse and Oakland squatters generally. Here are some videos:
