Well, I won't jump on the 'you're daft' bandwagon, and you do have my sympathy.

Come on guys, this is a fellow lister who's lost his bike! Have a heart

You've nothing to loose by going to the Police - in fact you may be adding to a list of complaints against the guy which nails him.

No doubt they'll make you feel about an inch tall - as they do - but I guess it comes down to how much you want your bike back!
