Four of the biggest roberties in history

1. The Great Train Robbery of 1963 - This heist, which took place in England, saw a group of 15 men steal £2.6 million from a Royal Mail train. The robbers, who were led by Bruce Reynolds, tampered with the train's signals to make it stop, before overpowering the guards and making off with the cash.

The robbery took place in the early hours of the morning, with the gang tampering with signals on the train line to cause the train to stop. They then overpowered the guards and made off with the cash, which was being transported in mail bags. The gang managed to escape with the money without being detected by the police.

The investigation into the robbery was led by Detective Tommy Butler, who was able to track down and arrest many of the gang members. However, Bruce Reynolds, who was considered to be the mastermind behind the robbery, was not caught until 1968. He was sentenced to 25 years in prison.

2. The Knightsbridge Security Deposit Heist of 1987, also known as the "Loomis Fargo Heist,". It is a theft of £60 million (equivalent to approximately £120 million today) from a security deposit facility located in Knightsbridge, London. The robbery was carried out by a group of criminals led by Valerio Viccei, an Italian thief.

The heist was planned over a period of several months, with Viccei and his associates renting a flat opposite the deposit facility and carefully studying the routines of the security guards. On the day of the robbery, the group overpowered the guards and made off with the cash, which was stored in safety deposit boxes.

Valerio Viccei was eventually arrested in January 1988 in London and was later sentenced to 22 years in prison.

The Knightsbridge Security Deposit Heist was one of the largest robberies in British history and it captured the public's attention for months. It was considered as a very audacious and well-planned robbery. The incident had a significant impact on the security industry, with many deposit facilities across the country tightening their security measures in the wake of the theft. The incident also inspired a movie named “The Bank Job” which was released in 2008.

3. The Boston Museum of Fine Arts Heist of 1972 was a theft of 13 works of art from the Boston Museum of Fine Arts in Massachusetts, United States. The robbery occurred on the night of March 18, 1972. The stolen artwork included paintings by famous artists such as Rembrandt, Vermeer, and Flinck, and were valued at millions of dollars.

The robbery happened, when the museum was closed to the public. The thief or thieves entered the museum through a window, and proceeded to steal the artworks, which they removed from their frames. The incident was discovered the next morning by the museum's staff. The police were immediately notified and an investigation was launched, the stolen artwork was never recovered.

The incident was a major shock to the art world, as the Boston Museum of Fine Arts was considered to be one of the most secure museums in the country. It also marked one of the first times that a major art museum had been robbed in the United States. The museum still has empty frames hanging on the walls as a reminder of the stolen paintings. In addition to the lack of recovery of the stolen artworks, another interesting aspect of this heist is that the robbers left behind a note that read "Thank you for the poor security." This note added to the shock and embarrassment of the museum and the authorities that were in charge of the security of the place. The case is still open and the museum continues to offer a reward for any information that leads to the recovery of the stolen artworks.

4. The Great Bullion Robbery of 1855 was a theft of £28,000 (equivalent to approximately £3.5 million today) worth of gold bullion from a London-bound train. The robbery was made on May 15, 1855, and it was considered to be one of the most audacious and significant train robberies in British history.

The robbery took place on a stretch of railway line between London and Folkestone, where the train was stopped by the robbers who had tampered with the signals. They boarded the train, overpowered the guards, and made off with the gold bullion which was being transported in mail bags. The gang managed to escape with the money without being detected by the police.

The investigation into the robbery was led by the police and the railway company, but despite numerous leads, the criminals were never caught, and the gold was never recovered.
