What could have been the diamond heist of the century took place over a decade ago. In February 2003, six thieves broke into the Antwerp Diamond Center. Leonardo Notarbartolo, the leader of the gang, had an identification card from the building which provided him 24/7 access to the Diamond Center. Leonardo and his team had to work their way through strident security mechanisms: Doppler radars; heat and motion detectors; a lock with 100 million various combinations; and even a magnetic field.
Their efforts would have been successful had it not been for a single sandwich which blew up the whole operation.
Leonardo threw all of the security footage tapes and several documents into a garbage bag and dumped it near the crime scene. When the police found the bag, they also found a half-eaten salami sandwich in it. The DNA found on the sandwich matched that of Notarbartolo.
