It sounds like something from a Hollywood movie — but it’s a true story now hitting Netflix screens in The Diamond Heist, the new docu-drama produced by legendary director Guy Ritchie. And what many viewers may not realise is that a quiet corner of Kent — near Tonbridge — played a key role in the downfall of the gang behind what would have been the biggest diamond heist in history.
In November 2000, a group of criminals attempted an audacious raid on the Millennium Dome (now The O2) in London, aiming to steal the De Beers diamond collection — including the priceless Millennium Star. Their plan involved a JCB digger smashing through the Dome’s walls and a James Bond-style getaway via speedboat. The haul? An estimated £350 million worth of diamonds, which in today’s money would be worth around £700 million.
But thanks to a long undercover operation by the Metropolitan Police’s Flying Squad, the gang never got their hands on the jewels. And it all started to unravel thanks to an unexpected incident just a few miles from Tonbridge.
The Brenchley Connection: A Sleepy Pub and a Costly Mistake
Terry Millman, one of the key players in the heist, made a fateful mistake on the roads of rural Kent. After reportedly falling asleep in his vehicle, he crashed into a fence outside The Halfway House pub in Brenchley — a village just a 15-minute drive from Tonbridge.
Although Brenchley technically sits within the Tunbridge Wells borough, the incident’s fallout brought the case firmly into Tonbridge territory. After the crash, Millman was arrested and taken to Tonbridge police station. It was here that police began surveillance on him — surveillance that would eventually lead them to a critical discovery.
Following Millman’s arrest, detectives traced him to a nearby farm in Brenchley, which was being used as a safe house by the gang as they prepared for the heist. Along with other sites in Kent and south-east London, this rural base was key to the planning stages of the raid — storing equipment like the JCB and other tools needed for their elaborate scheme.
From Kent to the Capital: A Plan Thwarted
Armed with inside information, hidden cameras, and hundreds of officers, police were ready when the gang struck. On 7th November 2000, just after 9am, the gang launched their raid — only to be met by a small army of waiting officers. The real diamonds had already been swapped for replicas, and the gang members were arrested almost immediately.
Among those jailed was Lee Wenham, who features heavily in the new Netflix documentary. Meanwhile, the story of Terry Millman — the man whose crash outside a village pub near Tonbridge helped kickstart the operation that foiled the heist — serves as a reminder that sometimes, even the biggest criminal plots can be undone by a small, sleepy mistake.
A Kentish Twist to a London Legend
For Tonbridge locals, the story adds a fascinating twist to a heist many only associate with London. It’s not every day that a fence outside a country pub and a trip to a local police station become pivotal moments in one of Britain’s most famous criminal capers.
The Diamond Heist is now streaming on Netflix — and it’s well worth a watch if you want to see how a few crucial moves, including one starting right here in Kent, brought a gang of audacious criminals to justice. We’ve gobbled up the whole series already!
