The Millennium Dome raid was an attempted robbery of the Millennium Dome's diamond exhibition in Greenwich, South East London occurring on 7 November 2000. A local gang planned to ram-raid the De Beers diamond exhibition, which was held in the riverside Dome. The gang had then planned to escape via the Thames in a speedboat.
The De Beers diamond exhibition had many jewels on display, including the Millennium Star, a flawless 203.04-carat (40.608 g) gem with an estimated worth of £200 million (equivalent to £425 million in 2023[1]) and considered one of the most perfect gems in the world. Also on display were priceless blue diamonds.[2]
The attempted robbery was foiled by the Flying Squad (led by Jon Shatford) of the Metropolitan Police Service as a result of information from Kent Police Serious Crime who already had the gang members under surveillance for their suspected roles in several unsuccessful armoured vehicle robberies. The operation to foil the robbery was the biggest in the Flying Squad's history. At trial, the judge commended the way it was carried out.[3]
If the heist had succeeded, then with a haul of £350 million worth of diamonds (equivalent to £744 million in 2023[1]), it would have become one of the biggest robberies in history.[2][4]
