JOHOR BARU (THE STAR/ASIA NEWS NETWORK)- A 70-year-old woman has claimed that her drug addict son sold off three of his four children to feed his addiction.

Man Tai Hoh, who lives in Larkin, alleged that her son has two children, aged seven and nine, with his ex-wife and two more, aged five and six, with his current girlfriend.

She said when her eldest grandson was only eight months old, her son sold the toddler off to a transgender person.

"My seven-year-old grandson was abandoned by his mother at my doorstep when he was about three-months-old and I have been raising him since.

"The remaining two children were also sold off by my son to fuel his lifestyle and he has, on various occasions, visited me and threatened to take away the child under my care," she said when interviewed.

Man said she is extremely worried that her son might return and one day also sell off the remaining grandson.

She had lodged police reports in 2011, 2014 and 2016, alleging her son's actions.

"I hope somebody can help me as I am already so old and have health issues like high blood pressure, diabetes and heart problems.

"I am afraid that when I am gone one day, my grandson will suffer the same fate as his other siblings," she said, adding that the RM300 (S$96) monthly she receives from the Welfare Department was not enough for them to get by as her grandson is studying in a Chinese vernacular school in Larkin.
