Told by the police who were there, this is the true story of Britain's biggest bullion heist. In November 1983, armed robbers stole £26 million worth of gold from the Brink's-Mat security depot near London's Heathrow airport. The nation was gripped as the robbers escaped with 6,800 bars of gold with an equivalent value of nearly £100 million at today's prices. (thetvdb.com)
