How is he a tenant? He doesn't own any property. The last owner just let him park his Van there and he paid for Bathroom/electricity. There's also no written contract allowing him to be there. Just was a handshake agreementThe guy is a tenant. That makes it a civil matter, not a criminal one, so the police aren't the answer.
Find a lawyer who does LL/T law in that jurisdiction. Find the money somewhere to pay the lawyer (get quotes and shop around if need be), because this guy will cause damage and sour the other tenants. Whatever you spend on a lawyer will be less than the damage he can cause.
