If the police refused to do anything the last time, it sounds like they did not consider it an actionable assault, probably because no one made a claim he acted improperly. I doubt they will consider it now that you changed your mind. You can phone them up and see and tell them you are afraid he will again start a physical fight. Assuming he has never been asked to pay rent, in California he would be considered a guest so could be told just to leave as he has no right to be there. Why does he want to establish residency? He is not going to be a resident there. Order him out and if he will not leave give him a three day notice and threaten to take him to court.
