Knightsbridge Safe Deposit Robbery (1987 UK)

In 1987 in Knightsbridge, London, 2 men entered the Knightsbridge Safe Deposit Centre asking to rent a safe deposit box. When they were brought to the vault, they pulled out handguns and subdued the guards. They then proceeded to hang a sign on the door explaining that the Safe Deposit Centre was temporarily closed, allowing more accomplices in simultaneously. This let them take their sweet time in ceasing the greatest sum of money possible. They busted open the safe deposit boxes and made off with what is estimated to equal $111 million. Police eventually discovered a finger print of a man named Valerio Viccei, and he and many accomplices were arrested the following month after a series of planned robberies. He then went on to write a book about his exploits.
