One of the largest bank robberies were committed by only two people. July 12, 1987 two unidentified men entered the bank, ostensibly to check their cells. Security reacted attentively to these visitors (not customers, after all), and the criminals were able to carry a gun.
As a result, security has been neutralized, and the criminals hung a sign "Depositary temporarily closed," and began to line the pockets of values. Of course, it's a figure of speech, for 174 million dollars in any pockets will not fit.
