300 Million Yen Robbery in Tokyo, Japan.
December 10, 1968 – A Nihon Shintaku Ginko Bank car, transporting 300 million Yen ($817,000 US) in its trunk, is pulled over by a policeman on a motorcycle, who warns them of a bomb planted underneath. Since there had already been bomb threats against the bank, the four passengers exited the vehicle as the uniformed patrolman inspected below the car. Moments later, smoke and flames could be seen under the vehicle, causing the men to run for cover. Of course, it turned out the smoke was from a flare and the cop was a phony. He jumped in the car and sped off with the loot. Even though there were 120 pieces of evidence, 110,000 suspects and 170,000 police investigators, the man was never caught.
In 1975, the statute of limitations ended, and in 1988 all civil liabilities were voided, but still no one confessed.
