Violent resident in the Assisted Living Facility my aunt is in. Shouldn't they relocate this resident?

I transfered my 95 year old aunt to a secured ALF and she is in a wing with 8 apts. The residents are allowed to wander in an out of each others rooms and they have a common room at the end of the hallway where they can gather for meals or mingle, read or watch tv. She is fairly happy there except for the fact that she has witnessed one of the residents become violent with the caregivers on duty. I was told this by one of the caregivers on duty and have seen evidence of this behavior (my aunts faucet in her kitchen was bent all the way down!) had to have it replaced. And I have witnessed this resident banging on doors trying to get out. And I had a caregiver in to visit my aunt for the first week and the caregiver told me of this residents violent behavior. I was under the understanding that violent behavior would not be tolerated. For the most part this violent resident is docile and just walks up and down the hallway and will stop to say hello. But the outbursts concern me and I think this resident has the potential to do harm to other residents. What do I do? Can't they medicate this resident or make them relocate? Where would they relocate this resident? Nursing Home? I hate to move my aunt again as she is adapting and seems to be doing well. Advice on how to approach this would be appreciated.
