On 17 May 2000, at a vacant plot of land in Bukit Timah, 36-year-old odd-job worker and moneylender Leong Fook Weng (Chinese: 梁福永; pinyin: Liáng Fúyǒng) was found dead, wearing only his underwear and sustaining several stab wounds on his chest and neck.

Investigations showed that Leong had been attacked and assaulted by four secret society members, and died as a result of a knife wound to his heart.

[1] On 17 May 2000, at about 11am, a man clad only in his underwear was found dead in a vacant plot of land near a cemetery along Kheam Hock Road, which was located somewhere in Bukit Timah.

[5][6][7] The victim was 36-year-old odd-job worker Leong Fook Weng, who was also a gang member and engaged in moneylending activities,[8][9][10] and he went to prison twice for fighting with someone.

[16] After weeks of investigations, the police eventually found out through witnesses that Leong, who was attending a funeral wake at Upper Boon Keng Road, had been approached by at least four disorderly men who assaulted him and forcibly brought in into the vehicle of one of the men, and he was also beaten up at a petrol station in Tanjong Katong before he met his end at Kheam Hock Road.

The vehicle, a white Mitsubishi Lancer, was traced and it belonged to a 34-year-old Singaporean citizen named See Chee Keong, who was recorded to have left Singapore a day after the stabbing.

On 31 May 2000, a 19-year-old National Serviceman named William Ho Kah Wei (alias Soh Tan Huat) was arrested by the police as a suspect.

It was found that throughout the assault and subsequent murder of Leong, Ho was present and witnessed the crime, but had failed to report the matter to the authorities.

[23][24][25] In December 2000, the Singapore Police Force were notified that one of the murder suspects, See Chee Keong, was imprisoned in Cambodia for a drug trafficking offence.

[26] Similarly, in March 2001, Robson Tay was arrested for drug trafficking in Paris, France and the Singapore authorities were notified of his whereabouts.

Tay was a member of Lo Kuan while the remaining three – See, Lim, and Ong – were part of another gang named Sio Ang Koon.

The fifth accomplice and Sio Ang Koon member, William Ho Kah Wei, was present all along throughout the events before and during Leong's killing, but kept silent and never report the matter to the police.

[13] On 5 February 2003, 22-year-old William Ho Kah Wei was found guilty of failing to report an alleged murder offence to the police.

In March 2001, the Singapore Police Force were notified that Robson Tay was in Paris, France, where he was facing trial for trafficking 5kg of diamorphine.

[36] Before his involvement in the murder of Leong, Tay had a long list of antecedents for various offences, starting from 1985, including being a member of a secret society, illegal money lending, cheating, and even reckless driving.

[42] On 28 February 2003, during his trial at the High Court, 36-year-old Robson Tay Teik Chai pleaded guilty to a reduced charge of culpable homicide not amounting to murder, which was equivalent to manslaughter in Singaporean legal terms.

On 3 December 2000, See was caught at Phnom Penh International Airport in Cambodia while attempting to smuggle drugs to Kuala Lumpur, Malaysia.

Deputy Public Prosecutor (DPP) Anandan Bala sought the second-highest sentence of ten years' imprisonment in See's case.

[54] Delivering his oral grounds of decision, Justice Chan stated that the case against See was full of aggravating factors, given that See was the only person armed with a deadly weapon and also fatally stabbed the victim to death.

Despite his sentencing remarks, Justice Chan personally addressed See, telling him that he was fortunate that his family and children were willing to accept and love him, noting that See's daughter had plans to allow her father to live with her and her son, and the judge told See that he hoped See would learn his lesson and stay away from crime ever again after his release.
