A group of protestors have scaled Tower Bridge near to where David Blaine is continuing his 44 day stunt in a glass box. They are trying to highlight the plight of an Essex man imprisoned in Greece.

Campaigners targetted David Blaine's stunt to go 44 days without food - as Simon Chapman from Basildon started a hunger strike in jail.

Chapman was arrested during a demonstration against a European Union summit in Greece last June. Supporters say a bag containing petrol bombs was planted on him and he is innocent.
