Brink's-Mat robbery: In London, 6,800 gold bars worth nearly £26 million are stolen from the Brink's-Mat vault at Heathrow Airport.
The Brink's-Mat robbery occurred at the Heathrow International Trading Estate, London, United Kingdom, on 26 November 1983. £26 million (equivalent to £89.7 million in 2022) worth of gold bullion, diamonds, and cash was stolen from a warehouse. The bullion was the property of Johnson Matthey Bankers Ltd, which collapsed the following year after making large loans to fraudsters and insolvent firms. Two men were convicted, and the majority of the gold has never been recovered. Insurers Lloyd's of London paid out for the losses, and several shooting deaths have been linked to the case.
