On October 8, 1988, 12 prisoners from Youngdeungpo Prison escaped into Seoul city during their transfer to Kongju Prison. Although they were known to Koreans as cruel and inhumane criminals, they were actually accused of robbery and other small crimes. They escaped because they were enraged by the idea of “Preventive Custody Policy,” and that trials were conducted unfairly to the poor. Their prison term for stealing 5,000,000 won was longer than that of Jun Kyung Hwan, brother of the former Korean president, who had embezzled approximately 60,000,000,000 won.
