It was a plot worthy of a James Bond movie and would have been the heist of the Millennium had it not been for the Met Police’s Flying Squad’s operation to foil the plan of some of Britain’s best and most wanted criminals.

In 2000, a gang of villains from the South East of England hatched an audacious plan to steal the world's largest perfect diamond from the Millennium Dome and make their getaway by speedboat up the River Thames. If they’d succeeded, it would have made the spoils of the Great Train Robbery and Brinks Mat look like loose change. The gang nearly had it all. They came within a whisker of unimaginable wealth, but it was snatched from under them by one of the most daring police operations ever.

Presented by Mark Austin, Diamond Geezers tells the full and thrilling story of the robbery that went wrong and the police operation of the century. From the crime's conception and execution to the notorious trial and appeal, it's a gripping account of a remarkable… real crime.
