South Korean Police Refer 54 Suspects in KRW28.7bn Casino Laundering Probe

South Korean police have referred 54 suspects to prosecutors for allegedly laundering KRW28.7 billion (US$21.4 million) in proceeds from an overseas investment fraud scheme through casinos, including Kangwon Land. The Busan Metropolitan Police Agency announced the referrals on Thursday and said 14 suspects remain in custody, including the alleged ringleader. Investigators traced the operation to a fraud that affected 555 victims and began in October 2025.

How police say the laundering worked

The investigation found the fraud started with an overseas investment organisation promising high returns via a fake website. The syndicate collected funds from victims and then sought to convert those proceeds into cash through South Korean casinos because commercial banks made large cash withdrawals difficult.

Police allege the network recruited two types of intermediaries: casino VIP customers and individuals with overseas permanent residency who could access foreigner-only areas within casinos. Participants reportedly bought chips using casino-designated accounts. After operators froze accounts, suspects allegedly switched to using cheques. At baccarat tables, members are said to have bet on opposing outcomes to limit net losses, then redeemed remaining chips for cash. People handling the exchanges allegedly earned commissions of around 2% to 3%.

Evidence seized and assets preserved

Authorities seized approximately KRW111 million in cash and luxury goods and confiscated around 50 mobile phones and computers. Investigators also obtained court approval to preserve roughly KRW390 million in assets, including property, for possible confiscation. Those asset measures are separate from the referrals to prosecutors and are intended to secure funds pending criminal proceedings.

Police recommendations to casinos and regulators

The Busan Metropolitan Police Agency urged casino operators and the Ministry of Culture, Sports and Tourism to tighten checks on high-value betting and cash withdrawals. Police described the casino channel as attractive to launderers because it allowed conversion of large sums of cash and because foreigner-only areas provided additional access routes for intermediaries.

The agency said prosecutors received cases involving a further 40 suspects whom police did not hold in custody. The referrals to prosecutors and the preserved assets now shift the matter into the prosecutorial phase, with potential indictments and asset-forfeiture actions to follow.

Why casinos were central to the scheme

Investigators told Yonhap News Agency that casinos offered practical mechanisms for turning fraud proceeds into ostensibly legitimate cash. The main features police highlighted were:

• availability of casino-designated accounts to purchase chips;

• use of VIP customers and overseas permanent residents to access foreigner-only properties within casinos;

• table play strategies, such as betting on opposing outcomes, to minimise losses and then cash out remaining chips;

• switching from frozen accounts to cheques when operators intervened.

Those operational details explain why police have asked for stricter monitoring of large in-casino cash movements and high-value redemptions.

Legal and sector implications for operators

The referrals and asset preservation orders increase scrutiny on casino anti-money laundering controls. Operators that host high-roller customers may need to review internal controls, particularly around designated accounts, cheque handling and the monitoring of play patterns at tables such as baccarat. The police call to the Ministry of Culture, Sports and Tourism frames this as both an operational and regulatory issue; the ministry is named by police when urging stronger checks.

Regulatory attention could translate into updated guidance or formal rules for casino reporting thresholds and customer verification processes. Platform and compliance teams should expect prosecutors to focus on paper trails linking chip purchases and redemptions to the originating fraud proceeds.

What investigators disclosed about the fraud timeline and scale

Police say the laundering began in October 2025 and involved 555 victims who were persuaded to invest via a falsified investment website. The total amount traced through casinos is KRW28.7 billion, which police convert to approximately US$21.4 million. Fourteen suspects remain in custody, including the alleged ringleader; prosecutors received additional files on 40 suspects not held by police.

Where this sits with wider enforcement

The case adds to a string of investigations where cash-intensive entertainment venues are used to move illicit funds. It also illustrates the investigative focus on transactional patterns — not just single large withdrawals — and on intermediary networks that recruit insiders or privileged customers to assist in laundering. Operators and compliance vendors working in the casino sector should monitor any regulatory responses from the Ministry of Culture, Sports and Tourism and any prosecutorial outcomes from the Busan Metropolitan Police Agency's referrals.

"Police said participants initially bought chips through casino-designated accounts," the Busan Metropolitan Police Agency said, summarising a key procedural step.

The agency added that when accounts were frozen the network adapted by using cheques and modified betting to secure cashouts for laundering purposes.
