Alton Towers theme park in Staffordshire has revealed some unusual finds after starting a clear-up of the site surrounding its Corkscrew rollercoaster, which is due to close next month.

The ride, which became Europe's first double-loop rollercoaster when it opened, will carry passengers for the last time on 9 November after nearly 30 years in operation, and is set to be replaced by a new attraction at the park. Items found by staff during the clean-up process, which got underway at the end of October, include a diamond wedding ring and a prosthetic leg. Since opening in 1980, 800 pieces of jewellery, 53 shoes and 237 mobile phones have been found at the ride site.

Russell Barnes, divisional director at the Alton Towers Resort, said: "As the Corkscrew is the oldest rollercoaster in the park, we were expecting to find some strange items when we started cleaning the area, but a prosthetic leg definitely tops the list as the most bizarre. "If anyone has any information on the missing leg, we would be keen to hear from them."
