Wang Shuiming and Heishan Arrested, Leading to Singapore's Largest Money Laundering Case in History, with Encrypted Assets in Accounts Exceeding $110,000

Singapore’s most serious money laundering case in history continues to unfold. The main suspect, Wang Shuiming, has been arrested in Montenegro and will face extradition back to Singapore. According to the latest investigation by Singapore police, this seemingly independent criminal group actually forms a complete cross-border “industry chain,” from illegal gambling scams in Southeast Asia, to money laundering through cryptocurrencies, to investing in overseas high-end assets—each link carefully designed.

Wang Shuiming’s partner Su Weiyi: From Hong Kong crypto platform scam to international manhunt

Wang Shuiming’s core partner, Su Weiyi, has a complex background. He is confirmed to be the mastermind behind Hong Kong-based cryptocurrency exchange Atom Asset Exchange. At the end of 2022, the platform suddenly faced withdrawal difficulties and eventually shut down. During this process, Su Weiyi transferred 16.74 million HKD (about 15.675 million RMB) before fleeing. It wasn’t until mid-2024 that he was arrested by Hong Kong police.

What’s more notable is that Su Weiyi and other partners operate multiple companies, all linked to former Filipino-Chinese mayor Guo Huaping, who has been convicted. This indicates that the criminal network is not only large-scale but also involves complex interests across multiple countries.

Large-scale Singapore raid: uncovering a 3 billion SGD money laundering case

On August 15, 2023, Singapore police launched an unprecedented large-scale raid with over 400 officers. During the operation, they dismantled the “Fujian gang” criminal group based in Singapore and arrested 10 suspects. These individuals, aged 31 to 44, are all from Fujian and hold multiple passports, with carefully concealed identities.

Investigations show that this criminal group operates systematically: they forge various documents, register shell companies, and transfer funds via cryptocurrencies to “clean” illegal gambling and scam proceeds from Southeast Asia. They then invest in luxury properties and cars in Singapore and abroad, ultimately legitimizing the illicit money.

Wang Shuiming’s asset empire: a transnational wealth network

According to in-depth investigations by Singapore police, Wang Shuiming’s wealth outside Singapore is also staggering. In China, his business investments amount to 32 million RMB, and he owns a factory worth several million RMB. In Xiamen, Wang owns two apartments valued at about 20 million RMB.

In Hong Kong, Wang has a bank account with HKD 2 million in cash. Notably, he also holds cryptocurrencies worth $110,000. The presence of these digital assets highlights the group’s reliance on cryptocurrencies—due to their high cross-border liquidity and difficulty in tracking—making them a key tool for international money laundering.

Lessons from multi-country cooperation in combating cross-border crime

This case demonstrates the strong international cooperation among law enforcement agencies in Singapore, Hong Kong, China, and other countries. From the initial investigation into the platform’s collapse, to tracking the transnational criminal network, and finally to capturing the core suspects, each step reflects the agencies’ commitment to cross-border collaboration. The arrest of Wang Shuiming and others sends a clear message to international criminal groups: no matter where profits are made in the world, they are ultimately subject to legal sanctions.
