The Brink's-Mat robbery was one of the largest robberies in British history, with £26 million (equivalent to £111 million in 2023[1]) worth of gold bullion, diamonds, and cash stolen. It occurred at the Heathrow International Trading Estate, London, on 26 November 1983, from a warehouse operated by Brink's-Mat, a former joint venture between US security company Brink's and London-based company MAT Transport. The bullion was the property of Johnson Matthey Bankers Ltd. Micky McAvoy and Brian Robinson were convicted of armed robbery. Most of the gold has never been recovered. Lloyd's of London paid out for the losses, and several shooting deaths have been linked to the case.
