He moved out over a month ago and still owes me $160 for utilities. I ended up with some of his mail and he finally came by tonight to get it, but of course he didn't come with any money. I gave him his package but told him if he wants the rest of his mail he needs to pay me. He said withholding mail is a federal offense and that he would pay me later (yeah right). And of course no thank you or appreciation that I held his mail for him. So can he do anything against me? There's no proof I have any of his mail. I'm kinda concerned cause I have green. He can't get police to search the apartment or anything right?
