You can't sit in your official vehicle on the town square and binge on donuts as a police officer.

I also made a police report.Now, he left his furniture and I would like to know the appropriate action I should do before I get rid of the furniture? 

Also with her help you can screen her through the police department in the local jurisdiction where she is from.

I immediately rushed over to see what was going on as I do not live on the property and ended up at the police station to gain a copy of the report filed.I want to issue them both a first warning notice explaining that if something like this is to happen again, I have no choice but to use my discretion on a plan going forward.

You can phrase it as you understand the police were called because of a dispute and let them know they need to keep it quiet or move.

Tell him to call the police and/or get a protection order on them. 

The local police station will offer a "landlord" course which basically runs over your responsibilities to your tenants as well as the community.

Go with a friend and a police officer with video camera and have your friend video you entering the property, videoing each room and then taping you removing all food from the premises.

But, I'm trying to imagine what would be involved in policing it.  

What reason did the police give when they were called for not removing him?
