Thor Chwee Hwa, 57, has been sentenced to one year and 10 months in prison after admitting to her role in a massive embezzlement scheme. The sentencing on May 8 follows a nearly 20-year period during which she and her husband evaded capture.
A Record-Breaking Embezzlement Scheme
The case centers on her husband, Ng Teck Lee, 59, who was the president and chief executive of Citiraya Industries. The company recycled electronic waste for major computer chip manufacturers, including Intel, AMD, Infineon, and ST Microelectronics.
Between April 2003 and November 2004, Ng allegedly misappropriated more than 6,700kg of uncrushed computer chips. These were sold to overseas syndicates through shell companies, such as Pan Asset International, for repackaging and sale as standard products.
The illicit activity resulted in gains of more than US$51 million, equivalent to approximately $72 million at the time. Prosecutors described this as a “staggering amount,” marking the Corrupt Practices Investigation Bureau’s largest asset seizure against a single individual.
The Role of the Bank Account
Thor was not formally employed but was used to facilitate the movement of funds. In June 2003, she opened a personal bank account with Credit Suisse Hong Kong (CSHK) under the instructions of Ng and the company’s then-CFO, Gan Chin Chin.

Court documents reveal that Thor had no control over the account and did not perform any transactions herself. Instead, Ng held a limited power of attorney, and Gan operated the account on his behalf.
On July 10, 2003, the account received more than US$1.1 million from Pan Asset’s CSHK account. These funds were later moved through the purchase of securities and foreign currencies by Gan.
Two Decades on the Run
The couple fled Singapore in early 2005, shortly after Thor met with CPIB officers to assist in investigations. They initially resided in China before moving to Malaysia under the “Malaysia My Second Home” programme.
During their time abroad, Thor received financial support from her family and resided in a property transferred to her for no consideration from her brother. Despite confiscation proceedings, only US$23 million of the alleged US$51 million benefit was recovered.
The evasion ended on December 3, 2024, when the Malaysian Anti-Corruption Commission arrested the pair in Johor Bahru. They were repatriated to Singapore that same day.
What Happens Next
While Thor has been sentenced, the legal proceedings for Ng Teck Lee are still pending. Given the scale of the misappropriation, his trial may lead to further asset recovery efforts or significant sentencing. The status of Gan Chin Chin remains undisclosed in court documents.
