You can but you are going to have to have a good reason if you expect them to remove her. If you and your roommate are both on the lease and your sister is an unwelcome and abusive guest, which it sounds like, call the police and tell them that she showed up and attacked you and ask them to get her out of your apartment because she won't leave and she's beating on you. Of course, you will have to file a report that she assaulted you and you will have to obtain a restraining order against her. The police aren't going to help you if you allow her back at some point. They don't play games. You either want this woman out of your life and your apartment or you don't. My advice: Go into your local police station, file an assault report and ask them how to go about getting a restraining order against her and getting her out of "your" apartment. Tell them she showed up, won't leave and beats you up - that she's violent and irrational.
