SINGAPORE: A police officer failed in his appeal on Friday (Jul 31) to overturn his conviction and reduce his jail sentence for his role in the fatal abuse of a young Myanmar maid by his ex-wife and former mother-in-law.
High Court Judge See Kee Oon instead increased Kelvin Chelvamâs sentence to 11 years and six monthsâ jail. He had earlier been sentenced to 10 yearsâ jail after being convicted at trial over the death of Ms Piang Ngaih Don, who died on Jul 26, 2016, after months of physical abuse.
The 24-year-old victim weighed just 24kg when she died of brain injury with severe blunt trauma to her neck.
Chelvam, 47, was convicted in July 2025 on four charges. These included one count of voluntarily causing hurt by grabbing the maid’s hair and lifting her off the ground, and one count of abetting his then-wife Gaiyathiri Murugayan to voluntarily cause grievous hurt by starving her.
He was also convicted of giving false information to a police officer handling the case and causing evidence to disappear by dismantling a closed-circuit television (CCTV) recorder in his flat.
The Singapore Police Force previously said that Staff Sergeant Chelvam had been suspended.
On Friday, Chelvam appealed against his convictions for abetment and causing evidence to disappear, as well as his sentences for all charges except the one for giving false information.
The judge dismissed all his appeals and allowed the prosecution’s cross-appeal to increase the sentence for the charge of voluntarily causing hurt.
Chelvam’s ex-wife Gaiyathiri and her mother, Prema S Naraynasamy, are currently serving 30 years and 17 years in jail respectively for their roles in the case. Gaiyathiri also lost her appeal against her sentence.
BACKGROUND
Chelvam lived with Gaiyathiri and their two children â then aged four and one â in a three-bedroom flat in Bishan. Two tenants occupied one of the bedrooms, the court heard.
Prema, who had her own home, frequently stayed over to help care for the children and would share a room with Ms Piang Ngaih Don, who slept on the floor.
The Myanmar national began working for the family in May 2015 on a two-year contract – her first job outside her home country.
Although Chelvam was her registered employer, Gaiyathiri oversaw her day-to-day work and welfare.
The domestic worker agreed to Gaiyathiri’s conditions of employment that included having no mobile phone and no days off, on the understanding that she would be paid more and allowed to rest at home.Â
Chelvam had signed the employment contract, which required that she be given at least three adequate meals a day among other terms.
What began as verbal abuse escalated into physical violence from October 2015. By May 2016, Prema had joined in the abuse.
