I had a klepto roomate back in college. He tried to charge his dorm RENT to my card. He then tried to use it at a tattoo place. I called the cops and pressed charges against him, and moved out of the room. Before I left, I found his soc. sec # and dropped him from all of his classes (it was at the beg of a semester).
A couple weeks after pressing charges, I was in our lounge with a girl watching TV, around 2 in the morning. Next thing I see is the sheriff come off the elevator, go to my old room, and cuff klepto. He was in his pajamas (and had apparently been sleeping), and they cuffed him and took him down to the station. It was priceless! Before all of this, his dad tried to call me and pleaded not to press charges. I told him, he did it before (he charged $2K worth of J.Crew from an ex girl roomate and had it delivered to WHERE THEY LIVED! The girl didn't press charges), and this time he was going to pay.
