What happened to Netflix's The Diamond Heist thieves - from prison sentences to tragic deaths

An audacious heist that shocked London in 2000 is still a hot topic over 20 years later.

Known as the Millennium Dome Raid, the attempted robbery of million-pound diamonds was manned by a gang from London, who targeted a De Beers diamond exhibition, valued at over £300 million.

The James Bond-style burglary is explored in Netflix's new documentary, The Diamond Heist, which is available to stream now.

The three-part series, co-produced by action film legend Guy Ritchie, delves into how the group planned to steal The Millennium Star, one of the most valuable diamonds in the . While their plan went smoothly, the robbers didn't get far because the Metropolitan Police's Flying Squad was at the scene, waiting for the gang to strike.

But what happened to the perpetrators after they were caught?

Six out of the seven men involved in the heist were sentenced after a three-month trial at the Old Bailey. One of the perpetrators, Terry Millman, died of stomach cancer while awaiting trial.

Robert Adams

Robert Adams received a 15-year sentence and later died in prison.

Lee Wenham

One of the group members, Lee Wenham, dives into his account of events in the documentary. The now 57-year-old was sentenced to nine years in jail for his involvement in the heist and a prior attempted robbery.

Alongside the series, Wenham will also share his story in his upcoming novel, Diamond Gangster, which will be published on May 22.

Raymond Betson

Raymond Betson received a long sentence of 18 years in prison, later reduced to 15 years. Aged 39 during the heist, Betson drove the JCB digger that rammed into the Millennium Dome, giving the gang access to the diamond exhibit.

In 2012, he had another run-in with the law after an attempted raid at a Loomis cash depot in Kent. In 2014, Betson was consequently sentenced to 13 years in jail at Maidstone Crown Court.

William Cockram

William Cockram was arrested inside the De Beers exhibition, where he used a powerful nail gun to break the glass protecting the 203-carat diamond.

Like Betson, he was sentenced to 18 years, later reduced to 15 years on appeal.

Aldo Ciarrocchi

Aldo Ciarrocchi caused a distraction at the scene by throwing smoke grenades. Aged 30 at the time of the heist, the Londoner received a 15-year prison sentence, which was later reduced to 12 years.

Kevin Meredith

Kevin Meredith was not at the Millennium Dome. Instead, he was caught behind the wheel of a speedboat on the Thames, which was suspected to be the gang's getaway.

He was jailed for five years for conspiracy to steal.

The Diamond Heist is streaming now on Netflix.
