The suspect, identified as Han, who is 33 years old, arrived from Seoul. Intelligence gathered in South Korea enabled Thai officers to move swiftly. Han was alleged to have assisted a call center syndicate in laundering crypto using gold bar purchases. The scam began in early 2024, whereby victims were recruited on social media with offers of paid engagement activities. Later, fraudsters launched “investment opportunities,” which included high returns of 30 to 50%.

They developed trust by sending early profits and limiting withdrawals as people invested further. With time, the victims noticed that they had been scammed and launched complaints. The TCSD mounted an investigation, arresting ten suspects consisting of five money launderers and five mule account holders.

Han’s mobile phone was confiscated at the time of the arrest. According to authorities, it contains a number of cryptocurrency wallet credentials that are linked to laundered funds. The Thai and South Korean governments now continue their joint work on further investigation.

Thai police have arrested a 33-year-old South Korean man for allegedly laundering cryptocurrency for call-centre gangs by converting it into gold bars, with transactions worth more than 1.6 billion baht over a three-month period.

Crypto-to-Gold Laundering Scheme Exposed

Han was one of the significant figures in the crypto-to-gold laundering scheme. He collaborated with a South Korean firm that facilitated stolen crypto conversions. Moreover, he opened multiple accounts on crypto platforms to which the victims of call center frauds transferred digital assets. According to the officials, the company imported gold bars through foreign suppliers. These gold bars were further transported back to the criminal syndicate without involving financial oversight. Each laundering round involved at least 10 grams of gold worth of digital money.

In January-March 2024, approximately $47.3 million was processed through Han accounts, much of which was turned into physical gold through the laundering process. Officials stated that each transaction was over $1 million, making it one of the most advanced crypto scam operations in Southeast Asia thus far.

Han spent six years studying in China and returned to South Korea. There, he joined the scam company and began to process digital funds that were directly connected with illegal activities. Officers were also able to seize evidence showing direct links to international gold suppliers and logistics networks during the arrest. Though Han has refuted some of the claims, he did acknowledge his involvement in crypto-related activities. Authorities are currently extending the investigation so as to expose every entity involved in the fraud ring.
