We have seen a lot of robbery scenes in TV dramas, generally speaking, this is to be committed by gangs, but in the history of Japan, there has been a robbery, also known as the most perfect crime in Japanese history, why do you say so? Because this criminal snatched 300 million yen by one person, although more than 100 pieces of evidence were left at the scene, more than fifty years have passed since then, and this robbery has not been solved until now.

In 1968, the manager of a Japanese bank received a letter stating that he should prepare three million yen or plant a bomb in the manager's home. After receiving the news, the manager quickly called the police, and the police also arranged more than fifty police officers near the manager's house, hoping to wait until the criminal appeared to arrest him. But a few days passed, and no criminals appeared at all, so it was often considered a threat, so the manpower was withdrawn.
A few days later, a cash truck came out of the bank with bonuses for Toshiba employees, with 300 million yen in cash. Not long after the cash truck came out, a mounted policeman stopped them on a motorcycle and told them that the manager's home had been planted with a bomb, and that there was also a bomb in this car, and that for safety, the employees needed to get out of the car for inspection. Because these employees knew about the manager, they did not doubt that he had him, and they got out of the car, and the mounted policeman said that the bomb was going to explode, and quickly drove away in the cash truck.
At first, these employees were still grateful, but then they reacted wrong. This mounted policeman must be the robber. So they immediately called the police. Within ten minutes, the local area can be said to be under total martial law. But even so, there was still no news of the criminal, and the criminal left more than a hundred pieces of physical evidence, but the Japanese police did not have any breakthrough. More than fifty years have passed, and the case is still a pending case.
