Olympic beach volleyball players are having problems in their sandy courts in London. Squirrels have been burying nuts and acorns on six practice courts at London's St James's Park and bikini-clad players have been feeling the pain as they land barefoot on the squirrel snacks.

Groundsmen now have to rake the sand before practice sessions.

Olympic officials say, "It's nuts but true. It seems squirrels have been invading the courts and either hiding or dropping their nuts.”

"But it won't affect the competition because the sand is regularly raked."
