Tenant Endangering Property and Roomates. NEED HELP

[Christian Ferreira]

Good Morning Everyone,

I need some advice badly. I have a serious situation on my hands right now. 

In one of my apartments, I rent it out as 3 separate bedrooms. All college students, which have only been there for about a month or so. Recently there was a noise complaint about one of the tenants playing the guitar in the early morning. I politely talked to the tenant and said he can play his guitar just not during certain hours. After this incident it went downhill, he started talking absolute non-sense. I am sure he has some sort of mental health issue, maybe schizophrenia or he is disillusional. I just got a phone call this morning from another roommate saying they are worried because the problem tenant believes someone is doing witch craft in the house, causing his brain to swell, and giving him headaches. The roommate said he was talking nonsense again about someone leaving the oven on, then she noticed when he was the only one home he went and turned two burners on and left the oven door open and on. She also said that he was being aggressive, rude, and somewhat threatening when she confronted him about it. She also hears him talking to himself about her and the other roommates, at this point she is becoming very worried and scared. 

The apartment is in Massachusetts, so evictions take a very long time. At this point I am stuck on what to do. I was thinking about going there with another person or two and telling him he needs to vacate immediately or I will have to notify the police? I also told the roommate to immediately call the police if she feels threatened or endangered by him. 

Any advice? I will also be contacting my attorney to see what advice he can provide. 

Thank you,

Christian
