Jakarta. An Indonesian court has ordered the seizure of more than Rp530 billion ($31.3 million) linked to an online gambling network allegedly operated by businessman Oei Hengky Wiryo, marking one of the largest asset recoveries tied to illegal betting in the country.

Prosecutors said the network ran at least 14 gambling websites for years before authorities dismantled the operation. The confiscated funds were formally transferred to the state on Friday by the West Jakarta District Prosecutor’s Office.

According to prosecutors, the seized amount totaled Rp 530 billion along with an additional Rp 1 billion fine that was paid into the state treasury through the Finance Ministry.

Head prosecutor Nurul Wahida Rifai said the gambling syndicate used a structured money-laundering scheme to disguise the proceeds of its illegal activities.

“The convict concealed or disguised the origin, source, location, or ownership of assets known to be derived from online gambling through several shell companies,” Nurul told reporters at the prosecutor’s office in West Jakarta.

Authorities identified two main figures behind the network: Oei Hengky Wiryo, 69, and an associate known as Henkie.

In 2018, the pair established A2Z Solusindo Teknologi, which was officially registered as a company engaged in trade and computer consulting services. Investigators later found the firm was allegedly used as a front to channel funds from illegal gambling operations.

Under the company’s structure, Henkie served as president director while Oei Hengky Wiryo held the position of chief commissioner and majority shareholder with a 60 percent stake.

Despite being registered as an information technology business, investigators said the company played a key role in controlling the operation of online gambling platforms.

Prosecutors said A2Z Solusindo Teknologi also acted as the beneficial owner of Trans Digital Cemerlang, a web portal company believed to host and manage the gambling sites.

Over roughly seven years, the network allegedly operated 14 online gambling platforms.Through these websites, users could place bets online and transfer deposits into designated accounts that were later consolidated by the operators.

“The proceeds from online gambling were then disguised by transferring them into accounts belonging to Oei Hengky Wiryo and several affiliated accounts,” Nurul said.

In a ruling issued on Feb. 11, the West Jakarta District Court found Oei Hengky Wiryo guilty of money laundering related to online gambling.

The court said he violated provisions under Indonesia’s Anti‑Money Laundering Law (Law No. 8/2010).

Judges sentenced him to two years in prison and imposed a Rp1 billion fine. If the fine is not paid, it will be replaced with an additional 190 days in detention.

The court also ordered the confiscation of Rp530.43 billion in assets as proceeds of crime.

Data from the Financial Transaction Reports and Analysis Center (PPATK) show that the total turnover of online gambling transactions in Indonesia fell 20% in 2025 to Rp 286.84 trillion from Rp 359.81 trillion in 2024.

The number of transactions reached about 422.1 million in 2025, while deposits dropped sharply to Rp 36.01 trillion, with around 12.3 million people recorded as participating.

Officials attribute the decline to tighter government coordination, the blocking of bank accounts and e-wallets used for gambling transactions, as well as a shift by operators toward alternative payment methods such as QRIS digital payments.
