The Brink's-Mat robbery occurred at the Heathrow International Trading Estate, London, on 26 November 1983. £26 million (equivalent to £100 million in 2019) 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 frauds 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 deaths have been linked to the case.
