South Korean police have apprehended 77 people suspected of involvement in an illegal online gambling network that allegedly handled 23 trillion won ($17.2 billion) in wagers through 188 websites. The investigation centres on a supply operation that provided casino video feeds, virtual gaming credits and ready-made gambling platforms to smaller operators.

Authorities said 21 suspects were detained following the investigation, which covered activities in South Korea, Vietnam and Cambodia between March 2023 and July 2026. The network allegedly generated around 150 billion won (112 million) in criminal proceeds, according to investigators. Police also traced 795 financial accounts and secured a freeze on suspected proceeds worth approximately $7.2 million. The case highlights how illegal gambling operations can rely on separate suppliers and website developers rather than building and managing every platform themselves.

Police Trace Network Supplying 188 Illegal Gambling Websites

The Chungnam Provincial Police Agency announced the arrests on October 19, describing the investigation as one of South Korea’s largest illegal gambling cases. Investigators said the network produced and supplied 188 gambling websites while selling gaming credits to operators.

Casino.org’s post on the investigation highlights the alleged $112 million in criminal proceeds and the supply of casino feeds, credits and ready-made websites. Police said the 77 people apprehended included 25 individuals linked to the supply operation, 33 associated with running gambling websites and 19 identified as gamblers.

Twenty-one suspects were detained, while investigators continued efforts to locate people believed to have fled overseas. The investigation began in November 2025 after police arrested individuals connected to lower-level gambling operations. Officers subsequently examined transactions involving 795 financial accounts and reviewed communications exchanged through overseas messaging services to identify people higher up the supply chain.

The network is operated across South Korea and Southeast Asia, investigators claim that members moved offices regularly, used overseas servers and relied on accounts held in other people’s names to make their activities harder to trace. Authorities said the operation involved separate groups responsible for supplying casino-related material, developing websites and managing gambling platforms. Police have also pursued organized crime charges against 24 people associated with the website-development business.

Developers Allegedly Built Casino Websites In 10 Minutes

Investigators said the network recruited developers with experience at major South Korean companies to create an in-house program capable of producing a website in around 10 minutes. The supply group allegedly obtained casino video feeds and virtual gaming credits through contracts with overseas gaming companies operating legally.

These materials were then passed to developers, who assembled ready-made platforms and supplied them to smaller gambling operators. The developers reportedly charged monthly maintenance fees of 3 million won, or approximately $2,250, for each website. Operators then recruited customers through adult-only internet cafés across South Korea and generated revenue by selling gaming credits.

Police estimate that the 188 websites processed approximately 23 trillion won in wagers over the period under investigation. That figure represents the total amount wagered, not the network’s earnings. Authorities said they had blocked 408 associated web addresses and secured a pre-indictment freeze on 9.6 billion won, approximately $7.2 million, in suspected criminal proceeds. Police were also seeking international assistance to locate 12 suspects believed to be overseas.

The investigation illustrates the distinction between gambling operators and the suppliers that provide the infrastructure they use. By targeting the website-development and supply operations, investigators sought to disrupt the services supporting multiple gambling platforms rather than focusing exclusively on individual websites.

Police have said they will continue pursuing suspects and investigating the financial activity connected to the operation. The allegations remain subject to the legal process, and the reported wagering total should not be confused with money earned by the network.
