Tenant's guest damages both units and common area in tantrum invo

[Zachary D.]

Tenant is an older man with limited visibility; already in the unit on a M2M lease. Left his unit unlocked today and his crazy woman friend came in and next think you know I'm hearing her and her girlfriend screaming and fighting, etc. Called police after hearing things breaking.

After I give police the address I ascend to the 2nd unit where the action is. I tell them I've called the police and that they need to leave. Not sure if I can do that or not but I did. One of the crazy women leaves, breaking a window and slamming a storm door clearly with the intent to break it. She knocked holes in tenant's walls, a couple holes in common area, broke a small window on other unit, and even threw over a couple of trashcans in the alley behind the house.

I obviously need to have a talk with my tenant. Noted. We're also going to have a new lease with guest limits, locking-door-required, etc. But what about the crazy people? Is there anything I can do to ban these two individuals from my property again? A restraining order or something like that? Police told me to speak with tenant but didn't really suggest any recourse for me personally. I didn't ask tbh, was a little overwhelmed with everything going on. Can I draw up a lease that says (more professionally, of course) "Jane Doe cannot be on property anymore since that clown messed up my house"?

EDIT - Home is in Milwaukee, WI

Banning a guest is tricky.  Most officers avoid enforcing anything like that because it is murky.  Banning a guest from a common area is absolutely within your right as a landlord because you have control over that space.  You have less control over the space in a tenant's unit.  I've had situations where the police wouldn't remove someone from the premise because she was in the tenant's unit and was not actively disturbing anything.  Only once I caught her loitering in the public hallway would the police remove her from the premises.   The only way I've ever been able to permanently resolve this issue is to remove the tenant associated with the guest. 

I've never tried the restraining order approach because I've been told you need more than your verbal word that they were the ones damaging the property.  So like CCTV footage, police sworn statements that when they arrived Teri Smith was in the process of breaking a window...etc.  But honestly, restraining orders are just pieces of paper.  Some people will walk straight through them and it is too late by the time the police respond to a call for it.  Just remove the tenant when given the chance.
