The Baker Street robbery was the burglary of safety deposit boxes at the Baker Street branch of Lloyds Bank in London, on the night of 11 September 1971. A gang tunnelled 40 feet (12 m) from a rented shop two doors away to come up through the floor of the vault. The value of the property stolen is unknown, but is likely to have been between £1.25 million and £3 million; only £231,000 was recovered by the police.
The burglary was planned by Anthony Gavin, a career criminal, who was inspired by “The Red-Headed League”, a Sherlock Holmes short story in which criminals tunnel into a bank vault from the cellar of a nearby shop. Gavin and his colleagues rented Le Sac, a leather goods shop two doors from the bank, and tunnelled during weekends.
The interior of the vault was mapped out by one gang member using an umbrella and the span of his arms to measure the dimensions and location of the furniture. The gang initially tried to use a jack to force a hole in the vault floor and when this failed they used a thermal lance. When this also failed to work, they used gelignite to blast a way through.
Once inside, they emptied 268 safety deposit boxes. The gang had posted a lookout on a nearby roof, who was in contact via walkie-talkie, and their radio transmissions were accidentally overheard by Robert Rowlands, an amateur radio enthusiast.
He called the police, who initially did not take him seriously, so he used a small cassette recorder to make a recording of the burglars’ conversations. The second time he contacted the police they accepted what he was saying, and began hunting for the burglars while the break-in was in progress. They searched 750 banks in an 8-mile (13 km) radius, but failed to locate the gang.
Police found the members of the gang soon after the break-in; one of the burglars, Benjamin Wolfe, had signed the lease for Le Sac in his own name and informers provided information that led to Gavin. At the end of October 1971 police arrested Wolfe,
Gavin, Reg Tucker and Thomas Stephens. They continued to search for other members of the gang, including one woman, for five years, but no further arrests were made. Gavin, Tucker and Stephens were sentenced to twelve years in prison; Wolfe received a sentence of eight years, less than the others as he was in his 60s.
