Dealing with bad people calls for the need of bad people.

Go find some indian guy that thinks he is very gangster type. Ask him to go talk to him. Pay him a sum to get rid of that guy.

Dont bother going through all the law and rubbish.

Next time please learn your lesson. Do not rent to these people. If u know what I mean.

Rent it to other types. M or C will be good. best is if u can get foreigner tenants.
