Loo-ser! Pranksters trap Clarkson

Pranksters trapped Jeremy Clarkson in a portable toilet - and posted a video on the web to add to the embarrassment.

The clip was filmed at a classic car rally on the Spanish island of Mallorca. It shows the 48-year-old Top Gear presenter struggling to free himself a cubicle after a group of laughing men piled up tyres against the door.

Eventually Clarkson kicked the door from the inside to knock down the tyres. He exited smiling and throwing up his hands as onlookers cheered and laughed.

Last month Clarkson was forced to apologise after he was filmed calling Prime Minister Gordon Brown a "one-eyed Scottish idiot".
