Ulsan Metropolitan Police Agency arrested suspects accused of laundering 270 billion won in criminal proceeds through gambling-site operations and voice phishing. Police said they detained 157 people from three organizations, including illegal money-laundering groups and those allegedly supplying and lending fake bank accounts. They sent 49 of them into custody under charges of violating the Electronic Financial Transactions Act. Investigators said the laundering organization secured more than 260 borrowed-name accounts between May 2024 and August 2024. Prosecutors allege the funds were laundered by making real-time transfers several times, with the group taking a commission of 0.4% to 1% of the laundered amount. Police said the operation differed from earlier cases because money laundering groups did not recruit borrowed-name account holders directly. Instead, they allegedly outsourced the work to a separate supply organization, a move police said reduced the risk of being tracked by investigators. The fake bank account supply organization members faced additional allegations: police charged seven of them with organizing a criminal organization. Police also said the proceeds of the crime were confiscated, totaling 430 million won. A police official added that many of the arrested borrowed-name holders later took part in crimes. The investigation is ongoing, with suspects including those sent to custody charged under the Electronic Financial Transactions Act.
