What bastards, same happened to me mate, cops won't do shit with fingerprints, we had the finger print guys come and take samples, never heard back and they got away with £1000's of "cash sale" power tools etc, things easy to sell.
I've learned from that though, now have a 3 year old akita and big fuck off pad bolts on the garage lol, if they want to break in they can feel free, then find everything locked up inside the door too
