No I can't say I've heard or seen anything like that happening in Bristol UK. I've seen the odd solitary shoe that has been accidently dropped out of a gym bag holdall and put up high on a wall for the owner to find it again or unintentionally discarded shoes or trainers after a heavy night on the beer usually found on Sunday mornings but not high on electrical wires. Shoes and clothes generally cost too much here to part with. As for stringing people up on a wire they just might do that in some areas!
