4. The Securitas Depot Robbery
Stolen: $83 million
In 2006, at a security services company’s warehouse in Kent, the greatest cash robbery in British history occurred. In preparation, an insider recorded the interior of the Securitas depot.
The branch manager was then kidnapped and kept prisoner by individuals wearing sophisticated masks. He was taken to the warehouse by the criminals, who forced him to allow them access to the currency cages.
The heist totaled $83 million. Some of the robbers were apprehended despite their ingenious disguises, and the makeup artist who created the masks became a major witness in the case.
