Not being funny, but if you do find out who it was, have them battered......
I found out who was responsible for the bungled attempt at breaking into my car and I had one of that lads 'visited' by some aquaintances from East London (wouldn't dream of doing it myself).
The lad was left in no doubt whatsoever why he was given the kicking, and was told that if he came within 100 yeards of my property again his house would be burnt to the ground whilst he slept in his bed.
Not expecting any vandalism any time soon.....
