Drama, farce, a radio ham and the Baker Street bank heist

The Baker Street bank heist was one of the most astonishing bank raids in history.

The gang tunnelled into a secure vault and made off with the contents of hundreds of secure deposit boxes.

It was reported that it could be anything between 500,000 and 3 m ( today 's equivalent of 6 m and 40 m) Only a fraction of the money was recovered and the rest went untracked.

The heist was the biggest robbery ever carried out in the Metropolitan Police district, with 120 detectives working on the case.

Scotland Yard said it was let down by the security staff of Lloyds Bank , who in turn said they had been assured their alarms were "foolproof" The story was still being reported in national and regional papers throughout the decade .

The only mystery that remains is what is in the 800 pages of sealed documents at the National Archives . They are due to be released in 47 years time. So what did Lloyds Bank say about the whole event? It advised customers to insure valuables kept in their safety boxes and denied any liability. After all, it said: "It is a little unusual for raiders to come up through the floor.".
