They detonated explosives to access the vault, making off with an estimated $20 to $50 million in gold, cash, stocks, and jewelry. The audacity of the heist, executed during intense civil unrest, shocked the international community. The stolen assets were never recovered, and the perpetrators were never apprehended.
