My attorney and my home insurance adjuster have both said I should file a Police report, and pursue damages.

The city isn't currently strong on policing BUT you could get into trouble if one of the neighbors is an str hater and documents the guests/nights.

There is a zero percent chance the police are going to remove an occupant who has lives in the property. 

Normally you should call the police, but it may not be worth it and will inflate an issue that most likly is going to go away by itself once you have rented your property.
