my ex-roommate was given notice by his internet company that someone in the house downloaded some illegal movie. he assumed it was me, kicked me out and sent my things to me within days. he kept my computer, after using it without my permission, and told the police my computer was the one used to do the illegal download, and gave them my computer as evidence. all of this done without my knowledge,permission or proof. this was done in early febuary. i have not to this day heard a single thing from this guy. can i start a lawsuit against him for theft of property or anything?
