On 10 July 2017, 69-year-old Tan Nam Seng (Chinese: 陈南成; pinyin: Chén Nánchéng; born 1948) stabbed his son-in-law, 38-year-old Spencer Sanjay Tuppani Shamlal Tuppani, in broad daylight at Telok Ayer Street, Singapore. Tuppani escaped and Tan gave chase, however Tuppani collapsed along Boon Tat Street and subsequently died from his injuries.

On 10 July 2017 at about 1.20pm, Tuppani was having lunch with three friends at a coffee shop along Telok Ayer Street when he was spotted by Tan who was driving past. Angry that Tuppani had been ignoring and avoiding his attempts to discuss business matters, Tan decided to enter the coffee shop and confront Tuppani. He told Tuppani "you are too much" in Hokkien, pulled out a knife which he had kept in his sling bag, and stabbed him three times in quick succession.[3] One of the stab wounds penetrated his main artery.[4] Tuppani ran towards Boon Tat Street while Tan gave chase, and eventually collapsed in front of a restaurant.
After Tuppani collapsed, Tan calmly put down the knife. He then called his daughter, Shyller Tan, over the phone, saying: "I couldn't sleep at night. I have already stabbed him. Don't cry. I am old already and I am not afraid to go to jail. What is done is done." When employees of the restaurant attempted to help Tuppani, Tan pushed them away, saying: "This is my son-in-law, don't help him, let him die." Tan calmly sat down and remained at the scene until police arrived and arrested him.
Tuppani was taken to Singapore General Hospital, where he was subsequently pronounced dead at 2.13pm.[5]
On 20 August 2020, the trial of Tan began. Tan pleaded guilty to one count of culpable homicide not amounting to murder. According to the prosecution, Tan was suffering from major depressive disorder at the time, which amounted to diminished responsibility. Tan's depression was caused by Tuppani having an affair with another woman, Joan Yeo Gek Lin, as well as worries that Tuppani was cheating him of his family business.
The prosecution asked for 12 years' imprisonment, citing that there should be a deterrent to other people from taking matters into their own hands. The defence asked for 7½ years, as due to Tan's old age, a longer sentence would practically be a life imprisonment.[6]
The company did not perform well between 2012 and 2016. When business improved in 2016, Tuppani suggested selling it to a bigger corporation. Tan, who was contemplating retirement, left the sale to Tuppani. Leading up to the sale, Tuppani persuaded some of the shareholders, including Tan and Shyller Tan, to assign their shares to him to boost his stake in the company, so the buyer of the company would not have control of it, which they agreed. The sale went through, and Tuppani was appointed CEO of the firm in December 2016. However, Tan was unhappy as he received only about S$450,000 from the sale of his shares.
In early 2017, Shyller Tan found out that Tuppani had been having an affair with Joan Yeo and had two children from the affair. They agreed to a divorce, but continued to live in the same household with Tan and frequently quarrelled over issues relating to the divorce. Subsequent events led Tan to believe that Tuppani was planning to cheat him of his business, by divorcing Shyller Tan, after taking control of all the shares.[1]
On 21 September 2020, High Court judge Justice Dedar Singh Gill sentenced Tan to 8½ years' jail, taking into account his major depressive disorder and his fast-deteriorating health. Tan was not caned as he was over 50 years of age. In the three years he spent in custody, Tan has contracted tuberculosis and suffered two heart attacks, requiring a bypass surgery, among other medical issues.[6]
In November 2019, Tuppani's mother, 62-year-old Tham Poh Kwai, sued Tan Nam Seng for damages resulting from the loss of her son. Tham said her loss amounted to $5,050 a month, comprising a monthly allowance of $2,000, rent, utilities and medication.[7]
In 2022, 42-year-old Jason Er Kok Yong (余国荣 Yú Guóróng) and 46-year-old Lawrence Lim Soon Hwa (林顺华 Lín Shùnhuá), two friends of Tuppani, sued the administrators of Tuppani's estate - Shyller Tan, her sister Sherry Tan San San (陈珊珊 Chén Shānshān) and Tuppani's first wife Felicia Keh Lay Hong (郭莉虹 Guō Lìhóng). Er and Lim demanded a share of a $4.6 million Lorong Mambong property that was tenanted to a pub, Wala Wala Cafe Bar, claiming they and Tuppani agreed to each contribute $535,200 in cash towards the purchase of the property. On 29 August 2022, Justice Mavis Chionh dismissed the lawsuit, finding various aspects of Er and Lim's evidence to be "full of gaps", "riddled with inconsistencies" and "highly suspicious".[8][9]
Tan Nam Seng was released from prison since December 2023.[10]
