My question involves an eviction in the state of: Indiana

We own an apartment house with a main level apartment which has 3 sleeping rooms and a common area (large kitchen), and one shared bath.

One of the tenants has his teenage daughter living with him. The other 2 rooms are occupied by men in their early 30s.

He constantly accuses the other two tenants of sexually harrassing his daughter.

He has his big, burly buddies come over to visit frequently and threatens to 'beat the _____' out of the guys who live there.

He has also threatened me, when I was there cleaning the awful filth they have made in the kitchen and bath, and even called the police on me, telling them that I 'barge right in' and see his daughter who is coming out of the bathroom (going through the kitchen to get to their room), even though this common area where I'm cleaning and otherwise doing maintenance is not private for him and his daughter only, and is a COMMON area (which the police did point out to him). He has stated to the other tenants that he is going to "get the landlord in trouble for sexually molesting his daughter"!

He drives every new tenant away with his threats. How can I get him and his daughter OUT? He always pays his rent on time.

Do I have grounds for eviction, and can it be IMMEDIATE eviction before something really bad happens??
