West Yorkshire Police
Perhaps it's time to rename West Yorkshire as Adam West Yorkshire, seeing as how the UK city appears to be home to a paunchy caped crusader who recently turned in a handler of stolen goods to the police.
The police would like to know his identity, but the woman who thinks she sold the costume to that mysterious masked man is keeping his true name (and credit card number) a secret.
I'd suggest investigating every expensive mansion house that looks as though it could house a cave underneath - but they're kind of a dime a dozen in England, right?
UPDATE: And...he's busted. See comments thread below.
