SINGAPORE – A mathematics teacher at an international school in Singapore had a sexual relationship with a 14-year-old student and manipulated her into keeping it a secret.

They engaged in sex acts on four occasions, and on two such instances, he instructed her to consume contraceptive pills afterwards.

The Singapore permanent resident from China, 29, who cannot be named due to a gag order protecting the victim’s identity, was on Monday sentenced to five years’ jail.

He pleaded guilty to three charges of sexual penetration of a minor, with two similar charges taken into consideration for his sentencing.

The court heard that the victim, now 17, is a Chinese national who came to Singapore in February 2019 to pursue an education.

The accused started teaching mathematics at the school in January that year. They became acquainted around March as he taught her class, and the victim would ask him for study materials.

They subsequently exchanged contact details and the victim would confide in him on issues she faced as a newly arrived foreign student.

On April 6 that year, the accused invited the victim and her friend, a 20-year-old man, to his house for lunch. Prior to her friend’s arrival, the teacher hugged and kissed her on the face.

As she was leaving, the accused asked her to be his girlfriend, and she agreed as she thought it would be good to have a teacher to care for her.

During their relationship, they kissed in school when no one else was around. They also had sex on four occasions at his home over a period of two months.

Deputy Public Prosecutor Colin Ng told the court: “The accused told the victim that it was a ‘natural thing’ for couples to engage in sexual intercourse.

“He also told the victim not to tell anyone about their sexual activities as this would harm her reputation and it would be ‘terrible’ for her if her parents found out about it.”

They broke up in mid-June that year, after the victim informed him that she had plans to transfer to another school. It was also the end of the school term and the end of the teacher’s employment with the school.

The girl later confided in a friend about the break-up and revealed that she had engaged in sex acts with the accused.

Furious, her friend took her to school to confront the accused, who persuaded the victim not to report the matter to the police.
