In May 2025, photographs circulated online showing convicted money launderer Su Haijin dining with Singapore ministers, billionaires Sam Goi and Oei Hong Leong, and a UOB heir, all taken before his arrest in the city-state's record S$2.2 billion money-laundering probe. The images, from private dinners that billionaire Sam Goi was reported to have paid for, placed some of the country's most prominent figures at the same table as a man who would soon be exposed as a central figure in Singapore's biggest financial crime case.
Su Haijin, a China-born Cypriot national, was among 10 foreigners arrested in simultaneous island-wide raids in August 2023. During the raid on his bungalow, he jumped from a second-floor balcony in an attempt to evade arrest and was found hiding in a nearby drain. On April 4, 2024, he pleaded guilty to one count of resisting arrest and two counts of money laundering, with 11 other charges taken into consideration, and was sentenced to 14 months in jail. As part of a plea bargain, he agreed to forfeit about 90 percent of his S$170 million in seized assets, including S$46.5 million in bank accounts and S$120 million in properties. Investigators also found that a company he owned had received nearly S$1.44 million linked to unlawful remote gambling operations abroad.
The case involved the seizure or freezing of S$2.2 billion in assets, from luxury properties and cars to jewellery, cash and cryptocurrency. The dinner photographs showed Su Haijin alongside Transport Minister Chee Hong Tat, Health Minister Ong Ye Kung, former minister Lim Swee Say, NTUC secretary-general Ng Chee Meng, "Popiah King" Sam Goi, billionaire Oei Hong Leong and UOB scion Wee Ee Chao. The government stressed there was no suggestion of wrongdoing by the dinner guests, but the images intensified scrutiny of how the city-state's elite circles had overlapped with the laundering network.
The probe prompted Singapore to set up an inter-ministerial panel to review anti-money-laundering measures, tighten oversight of financial institutions, and re-examine tax incentives for family offices. By late 2024, 15 suspects had agreed to surrender S$1.4 billion in assets and were banned from returning to Singapore. Su Haijin's case remains the most vivid symbol of a scandal that forced the financial hub to confront uncomfortable questions about the money flowing through its banks, casinos and property market.
The aftershocks of the case continued to ripple through Singapore's professional classes long after the convictions. In 2025, the Council for Estate Agents fined two property agents a total of S$7,000 for customer due diligence failures involving clients connected to the laundering network, a sign that regulators were pursuing accountability far beyond the original defendants. Seized properties began to be auctioned off, including units at Martin Modern and Wallich Residence that fetched S$16.3 million. The inter-ministerial panel set up in the wake of the probe reviewed everything from how banks onboard wealthy clients to whether high-value assets such as luxury cars and designer bags should face tighter regulation, and the government moved to re-examine tax incentives for family offices. For a financial hub that had long prided itself on both openness to global capital and a reputation for cleanliness, the S$2.2 billion case became an inflection point, proof that the two ambitions could collide in spectacular fashion.
