On 9 July 2026, three individuals were charged in Court with various alleged offences. They are:

b) Tan Tee Wah (“Tan”) (陈智华, 50-year-old male Singaporean), the sole-proprietor of Absolute Dzign and Contract Services (“Absolute”) at the material time of the alleged offences; and

c) Yeo Kah Wee Derrick (“Yeo”) (杨家伟, 51-year-old male Singaporean), a Senior Project Manager of Well Smart International Investment Pte Ltd (“Well Smart”) at the material time of the alleged offences.

Alleged Corruption Offences

2. Over separate occasions between 22 December 2022 and 15 February 2023, Yeo allegedly obtained or attempted to obtain bribes from Gan, Kass and another individual. The bribes were inducements for Yeo not to make things difficult for Kass’ and that other individual’s company’s operations in relation to two construction projects, the Mantra Club Croc Airlie Beach project and 23A Swettenham Road project, of which Yeo was the project manager. The bribes amounted to S$30,200, AU$20,000, and a two-night hotel stay valued at S$1,146.60.

3. Over multiple occasions between 12 June 2022 and 7 December 2022, Tan allegedly gave bribes totalling S$128,688 to Yeo. These bribes were inducements for Yeo not to make things difficult for Absolute’s operations in the 23A Swettenham Road project.

4. For his alleged actions, Yeo faces seven charges under Section 6(a) of the Prevention of Corruption Act (“PCA”), of which one is an amalgamated charge pursuant to Section 124(4) of the Criminal Procedure Code (“CPC”) and punishable under Section 124(8)(a)(ii) of the CPC. Correspondingly, Gan and Tan each faces three and two charges under Section 6(b) of the PCA, respectively. One of Gan’s and Tan’s corruption charges is an amalgamated charge pursuant to Section 124(4) of the CPC and punishable under Section 124(8)(a)(ii) of the CPC.

Alleged Cheating and Forgery Offences

5. Over nine occasions between 27 June 2022 and 13 January 2023, Yeo allegedly cheated Well Smart by dishonestly concealing that he would gain profits from the construction agreement between Absolute and Well Smart in respect of the 23A Swettenham Road project. Through Yeo’s deception, Well Smart was dishonestly induced to deliver S$892,366.02 to Absolute under the construction agreement.

6. On 24 September 2022, Yeo allegedly cheated Tan to reimburse him for lighting equipment purchased for the construction project. This resulted in Absolute paying Yeo S$1,748 for the purported lighting equipment.

7. On two occasions between 29 and 30 September 2022 Yeo allegedly forged two invoices for Professional Engineering Service Fees and a Residential Technical Officer service. The forged invoices were intended to deceive Tan into paying Yeo an amount totalling S$16,509.

8. On 25 October 2022, Yeo allegedly cheated Tan to pay for certain inspections to be carried out by a registered inspector. This resulted in Absolute paying Yeo S$9,929 for the purported inspections.

9. For his alleged actions, Yeo faces three charges for offences punishable under Section 420 of the Penal Code, of which one is an amalgamated charge under Section 124(4) of the CPC and punishable under Section 124(8)(a)(ii) of the CPC. Yeo also faces two charges under Section 468 of the Penal Code.

10. Singapore adopts a strict zero-tolerance approach towards corruption. Any person convicted of a corruption offence under Section 6 of the PCA can be fined up to S$100,000 or sentenced to imprisonment not exceeding five years or to both. Any person convicted of an offence under Section 420 or Section 468 of the Penal Code can be sentenced to imprisonment of up to 10 years, and also be liable to fine or, in the case of Section 420 of the Penal Code, to caning or to both. Any person convicted of an offence amalgamated under Section 124(4) of the CPC read with Section 124(8)(a)(ii) of the CPC can face two times the amount of punishment to which that person would otherwise have been liable for that offence.

11. Organisations are strongly advised to put in place robust procedures, in areas such as procurement and internal audit, to prevent falling victim to corrupt acts by their employees. Guidance for organisations on measures to prevent corruption can be found in PACT: A Practical Anti-Corruption Guide for Businesses in Singapore, which is available on CPIB’s website. Organisations are also strongly encouraged to obtain certification under the Singapore Standard (SS) ISO 37001 – Anti-Bribery Management Systems, which is designed to help organisations implement or enhance an anti-bribery management system to reduce corporate risk and costs related to bribery.
