Seller keeps coming back and harassing the workers

[Joe S.]

Seller keeps coming back and harassing the workers. So we bought a house and now the seller keep coming back every day According to the workers. He saying that they hauled  off new furniture which of course they didn’t. The seller had left a few things they were old and nasty and so as part of the clean out the workers did have to remove them. He told my workers today that he was going to come back and take down the chandelier. Also someone forced entry in the back door and broke the trim getting in the house last night. I do realize some people have a hard time coming to grips that they no longer own their former house so I have tried not to escalate things. At some point I feel like I’m going to have to solicit the aid of the police if this continues. Has anyone dealt with something like this and found away to neutralize this sort of activity peacefully?
