In September 1971, a gang executed one of the most astonishing bank heists in British history by tunneling into Lloyds Bank on Baker Street, London. With careful planning inspired by a Sherlock Holmes story, the group made off with valuables from numerous safety deposit boxes, all while being overheard by an amateur radio operator. The incident raised questions about police response and security measures, and its details remain partially unsolved decades later. Amidst rumors of government cover-ups and sealed documents, the raid’s legacy continues to intrigue.
