Reynolds was the brains of a gang that held up a mail train in southern England and made off with almost £2.6 million - worth around £40 million ($60 million) today. His son, Nick, confirmed he had died in his sleep on Thursday. Bruce Reynolds outside court in 1968. After five years on the run, he was tried and sentenced to 10 years in jail.

Nicknamed Napoleon, he was responsible for planning the raid by 15 men on the Glasgow-London post office train as it passed through the southern English county of Buckinghamshire on August 7, 1963. After the robbery, Reynolds went on the run with a false passport to Mexico, where he was joined by his wife Angela, and his son. They later moved to Canada, but their £150,000 share of the cash from the robbery ran out and he came back to England, where he was captured in 1968. Reynolds eventually spent 11 years in jail. After his release in 1979, he worked as a consultant on the film Buster, which starred rock star Phil Collins as fellow Great Train Robber Buster Edwards. But in the 1980s Reynolds was jailed for three years for dealing amphetamines and by the end of his life he was reduced to living on state benefits in a tiny London flat. Another member of the gang, Ronnie Biggs, famously escaped from prison after less than two years and fled to Brazil. Reynolds and his son, Nick, travelled to Brazil in 2001 to persuade Biggs to return to Britain after 35 years on the run to serve the rest of his prison sentence. Biggs was freed on health grounds in 2009. Nick Reynolds went on to be a member of the British band Alabama 3, who wrote the theme tune to the US TV mafia series The Sopranos. In 2003 Bruce Reynolds was reunited with John Woolley, the policeman who found the gang's hideout at a farm near the scene of the robbery. The pair shook hands during the meeting at a village fete and reminisced about old times. Family friend John Schoonraad said Reynolds had been suffering from a chest condition before he died. He said that despite his past, Reynolds was a "perfect gentleman" who no longer believed in crime. He said to me: 'Crime doesn't pay.' He's done his time, and he turned into a very nice man. I've always known him to be a real gentleman.
