How do you get on a coach wearing a false leg and then manage to get off the vehicle at your stop without it?

That is just one example of some of the more unusual items left behind on coaches operated by National Express.

A Chinese couple, who could not speak English, took a 10-legged crab on board a service from Coventry to Inverness, and even purchased a child's ticket for it.

Despite taking such care over the crab, they managed to get off the coach without it at some point.

As there were no seaside stops on the route a special coach was chartered to drop the crab off at the end of Blackpool Pier, on the advice of marine biologists.

National Express lost property manager Claire Horvath said: "It's absolutely unbelievable the things people leave on the coaches and on more than one occasion I've been left rubbing my eyes in the lost property room.

"The Indian head dresses were one of the more unusual items left behind. I mean, we've all mislaid glasses or a mobile phone but how do you forget something that size?"
