True crime feature documentary Blood Money: The Curse of the Brink's - Mat Robbery premieres on Tuesday 10pm, January 31st at Channel 5 and My5.

In November 1983, a gang of balaclava-clad armed robbers broke into the Brink's-Mat security depot near Heathrow and fled with pure gold, worth £26 million - equivalent to around £94 million today. Now nearly 40 years on, police officers and key witnesses, many speaking for the first time, reveal the inside story behind Britain's biggest gold robbery.
