In a significant breakthrough by law enforcement, South Korean police on Jeju Island have dismantled a large-scale illegal online gambling operation. This network, primarily targeting students and sailors, reportedly managed illegal betting activities worth over KRW 22 billion, equivalent to approximately $15.3 million, over several months.
The Jeju Provincial Police have apprehended 21 individuals suspected to be part of this organized crime network. Among those arrested, a 40-year-old man has been identified as the mastermind behind the operation. While charges have been officially filed against the ringleader and five accomplices, 15 other suspects were released after questioning. Additionally, the operation led to the arrest of 39 more individuals, including minors and active gamblers.
This criminal network had been in operation from October 2024 until its recent dismantling in July 2025, strategically choosing locations near educational institutions, internet cafes, and a villa as their operational hubs. These locations served as the primary venues for managing their extensive gambling activities.
An alarming aspect revealed by the police is the network’s involvement in usurious lending practices. They targeted students, offering loans at exorbitant interest rates that soared up to 650%. One disturbing case involved a student who ended up borrowing KRW 11 million, roughly $7,600, under such predatory terms. The total revenue generated from these illicit activities across the three main sites is estimated to be around KRW 9.2 billion, approximately $6.4 million. The police also seized KRW 250 million, about $174,000, during a decisive raid on one of the gambling dens.
Jeju Island is reportedly becoming a hotspot for illegal gambling activities. Besides the recent crackdown, authorities uncovered a separate betting operation targeting sailors, which had run from June 2024 to February 2025. In a related development, another group operating out of Seongwoo allegedly engaged in similar illegal gambling schemes throughout 2023.
The ongoing investigation aims to track down the elusive mastermind behind these operations. Authorities believe this individual may have relocated to Vietnam or another Southeast Asian country, using these locations as operational bases to coordinate with high-stakes gamblers within South Korea.
From the law enforcement perspective, a senior official from Jeju Island emphasized the relentless crackdown on illegal gambling sites. “We are taking a strict stance against such illegal activities, particularly due to the significant risks they pose to teenagers,” he remarked. He further assured that funds obtained through illegal means would be returned to their rightful owners, underscoring the commitment to justice and public safety.
The public has also been urged to exercise caution and refrain from sharing bank account information or transferring money on behalf of others, as these actions could implicate them in money laundering activities. This operation has underscored the serious approach South Korea takes towards combating illegal gambling and safeguarding its citizens.
However, it’s important to consider the broader context of illegal gambling in South Korea. Despite stringent regulations, the gambling industry in the country has a complicated history, with legal and illegal operations often overlapping. Some argue that the root cause of such extensive illegal operations is the restrictive nature of legal gambling opportunities available to South Koreans. With limited options for legal gambling, the demand for underground betting services remains high.
This viewpoint suggests that a reevaluation of current gambling laws might help reduce the demand for illegal services. By expanding legal gambling options and creating a more regulated environment, it could potentially lower the incentive for individuals to engage in unlawful activities.
Nevertheless, the government maintains a firm stance on its current policies, emphasizing the societal harm caused by gambling addiction and related criminal activities. They argue that any relaxation of gambling laws could exacerbate these issues, rather than alleviate them. The recent crackdown thus reflects the government’s commitment to uphold public morals and protect vulnerable groups from exploitation.
In conclusion, the dismantling of this illegal gambling network on Jeju Island is a testament to the effectiveness of South Korean law enforcement in dealing with organized crime. However, it also highlights the ongoing challenges of addressing the demand for illegal gambling in the country. As authorities continue their efforts to combat these illicit activities, the broader debate on gambling regulation is likely to persist. The outcome of this discussion could shape the future landscape of gambling in South Korea, balancing public safety with the potential benefits of a more open market.
