Illegal Online Gambling Operation Dismantled in South Korea
Crackdown on Illegal Gambling Ring in Jeju Island
South Korean authorities have successfully taken down a major illegal online gambling network on Jeju Island, which targeted vulnerable groups such as students and sailors. The criminal syndicate was involved in wagering activities estimated to exceed KRW 22 billion (approximately $15.3 million).
Police from the Jeju Provincial Police Department have arrested 21 suspects believed to be connected to this illicit operation. Among those detained, a 40-year-old man was identified as the leader of the organization.
Charges have been filed against the ringleader and five others, whereas 15 suspects were released after investigation. In addition to these arrests, authorities also apprehended 39 other individuals, including minors and gamblers who participated in the illegal betting.
The illegal operation functioned from October 2024 until July 2025, using strategic locations for its activities. These included spots near schools, two internet cafes, and a villa, which served as the main hubs for illegal gambling.
The group was also involved in loan sharking, lending money to students at exorbitant interest rates as high as 650%. One particular student reportedly borrowed KRW 11 million (around $7,600) under these terms.
From the three locations mentioned, an estimated KRW 9.2 billion ($6.4 million) was made through illegal gambling activities. Additionally, police seized KRW 250 million ($174,000) during raids.
Jeju Island: A Hub for Illegal Gambling
Further investigations have revealed other gambling operations on Jeju Island. A separate betting den, which specifically targeted sailors, operated from June 2024 until February 2025. Another gambling group based in the Seongwoo area also ran similar illegal schemes during 2023.
Law enforcement agencies continue to track down the mastermind behind the online gambling network. Authorities suspect the individual may have fled to Vietnam or another Southeast Asian country to coordinate and facilitate high-stakes gambling activities in South Korea remotely.
Authorities’ Firm Approach and Public Warnings
An official from Jeju Island issued a statement emphasizing the ongoing commitment to rooting out illegal gambling: “Our crackdown on such illicit sites is relentless, and we remain especially vigilant regarding the risks posed to teenagers.”
The official also assured that funds obtained through illegal gambling will be recovered and returned to their rightful owners.
The public has been cautioned against sharing bank accounts or transferring money on behalf of others, warning that such actions could lead to arrests for facilitating money laundering.
This dismantling operation highlights South Korea’s strong stance against illegal gambling and underscores the government’s dedication to protecting its citizens.
