Left my push-bike unlocked in Southwick Square whilst I did the shopping. Came back - someone had nicked the handpump off the frame. I was pretty cheesed off that they obviously thought that was worth more than the bike.....
My parents' car was broken into years ago. The offender was obviously disturbed in the process - because we gained a toolbag (with tools) and all we could work out was missing was a toilet roll.
