In an article by the Korean Times, a 26 year old female stated that she was working as a prostitute after defecting from North Korea. The woman stated that she borrowed $6,000 from a broker to obtain the necessary documents to help her defect to South Korea. The woman was told that she would be working at a karaoke bar in order to repay the loan.
Once in South Korea, the woman had her passport taken and was forced to work in a brothel. The woman would earn $70 for each session she had with a customer.
The sex industry in South Korea is estimated to be worth $12 Billion, with 46,000 brothels in operation.
