Anonymous for obvious reasons, but please keep it as such.
Okay, I really want to get this down somewhere as it's been driving me mad all day. To start, the last time I used my card was on the 8th, when I was getting money outside a shop. As such, I didn't check my wallet for my card and thus got a fright when I noticed it was gone today. I went to the bank and got a print-out of the latest transactions, cancelled the card, ordered a replacement, etc. It turns out my card was used twice yesterday, conveniently in the hour I had a lecture. Me and my flatmate had been up all night watching films, and at one point he went into my room alone to get a mug of his, which is when I suspect he took my card. Now, this may not seem like much at the moment, but on the 8th, we both got money out the same machine and he made a "joke" about seeing my PIN (I did think he seemed a little weird when he said it, but shook it off).
Now, I left for my lecture almost as soon as my lecture started (when he would have had the first opportunity to use my card). I managed to get the times and locations of the transactions, and unfortunately, in the first location, there are 2 ATM's and the one with the CCTV camera was out of order so no footage there. However, I found out the second, which is outside a shop, has a camera on the door of the shop. I convinced the manager to let me see the footage (I had been to the police and student services for my uni by this point) and he agreed, asking me to describe his clothing first. We got to the time the transaction was made and someone wearing the exact same clothes I described appeared, and the zoom confirmed it was him. Now there is no actual video of him using the ATM, but the exact time he is seen doing it and the only person who had the chance to know my PIN. Both machines had the PIN entered correctly first time, too.
I haven't brought it up with him as I have more things to sort out tomorrow, but I've just had to avoid him as I feel so angry I actually want to hurt him. I feel incredibly betrayed as I have been nothing but a great friend to him. I've lent him so much of my stuff and been incredibly generous. I feel completely used and I'm really struggling to keep rational. I have done nothing to deserve this and it's at the point where I actually hope he dies. Annoyingly we already have a deposit on a house for next year, so that just overcomplicates things unnecessarily.
I need advice... I want to prosecute him as I refuse to let a backstabber get away with theft and fraud. The lecture I was in had a relatively small turn out (25 people absolute maximum) and a few people I recognise (not friends) could likely vouch for my presence at the time. The CCTV in the shop correctly identified him at the time of the second transaction, my card has been cancelled and I have contacts to use tomorrow morning. I think I have done all I can, but I'm finding it very hard not to confront him now. I want to tell him I can get him prosecuted and demand my money back, and then be done with him for good, but what if this all one huge coincidence? Not likely in my opinion, but it's always possible. It just all adds up. Please help.
