CHATBOT: A bank robbery was described as the heist of the century, an ingenious plan of a mastermind to crack an impregnable vault. The events took place in a French bank named Saucity General, one of France's most well-known banks with branches all over the world. The bank is located in the city of Niss on the French Riviera. People used to save their valuable property in this bank, such as money, jewelry, and gold, as the bank had one of the biggest and strongest vaults in France. On Monday, July 19th, 1976, the bank's director and officers tried to open the vault to release funds for customer transactions. While the main door opened normally, the inner door remained stuck. They called the vault manufacturer company for assistance, and despite several attempts to unlock the door, it remained stuck. The customers waiting outside became increasingly impatient and worried. Frustrated by their inability to open the door, it was decided to break through the side of the vault door. The workman finally opened a small hole, only to discover that the bank had been robbed. The police were called, and the bank was swarmed with officers, as they realized they were dealing with one of the biggest bank robberies in history. The robbers had taken all the money from inside the vault, as well as 4,000 safe boxes containing valuable items. A quote was written on the wall, stating "without weapons, without violence, and without hate." The detectives wondered how the robbers had gained access to the vault and how they had managed to escape without being detected. It was later discovered that the robbers had used a tunnel leading to the city's underground sewer system, and the equipment they used to break into the vault was left behind.
