A teacher who headed his school's character and citizenship department had a sexual relationship with a 15-year-old student right up to two weeks before his wedding last year.
The teaching scholarship holder, now 33, robbed the girl of her innocence and used her as his sexual plaything, Deputy Public Prosecutor Kavita Uthrapathy told a court yesterday.
Then, he left the girl depressed and suicidal after marrying his fiancee in May last year.
The DPP said it was a worrying trend that five teachers had been convicted of having sex with their students last year. She is seeking a minimum six-year jail sentence for the man, who cannot be named to protect the girl.
Now jobless, he admitted to five out of 10 sex-related charges.
The court heard that the man was the girl's form teacher in 2011 and taught her English literature the following year.
After an overseas school trip in 2012, the girl began confiding in him about her family and struggles with her studies.
They exchanged messages on WhatsApp and Facebook, which became increasingly personal, before he began engaging her in conversation of a sexual nature.
She even sent him nude pictures at his request. The court heard that they had sex eight times, often unprotected.
The man led a double life, because he was also physically intimate with his fiancee all this time, the court heard.
The DPP said he would drive the girl to secluded locations, check into a budget hotel or take her to his parents' Kensington Park flat when they were away.
Once, he had sex with her after she lost a bet to him.The court heard that the girl began to diet and became self-conscious about her looks.
After the teacher was married, she sank into depression, scratching herself until she bled and having suicidal thoughts.
