A clever thief managed to bypass multiple layers of high-tech security and steal over $25 million of diamonds from a heavily guarded bank by using chocolates and charm.

Mr Claes [spokesman for the Diamond High Council in Antwerp] said of the thief: "He used no violence. He used one weapon -- and that is his charm -- to gain confidence. He bought chocolates for the personnel, he was a nice guy, he charmed them, got the original of keys to make copies and got information on where the diamonds were.

"You can have all the safety and security you want, but if someone uses their charm to mislead people it won't help."

As Bruce Schneier notes, "People are the weakest security link..."
