But Aaron Kok Chun Cheong, 23, will only start his sentence on Tuesday, Jan 4, 2011, as he wanted to spend the New Year with his family.
Kok, now a trainee at National Institute of Education (NIE), was in national service at the time of the offences in 2007 and 2008.
The court heard that he got to know the two girls through an Internet chatline in 2006.
He had sex with a 15-year-old student at a toilet for the handicapped in West Mall shopping centre on April 20, 2008, a day after his return from NS training in Taiwan.
Earlier in September 2007, he had invited the other girl, then 12, to his flat where he had sex with her in his bedroom.
The offences came to light when the younger girl was found to be pregnant and was warded in hospital in July 2008. The girl, who terminated the pregnancy, had told the police that she had engaged in sex with several male persons.
Kok was not the biological father of the foetus.
Three other charges were taken into consideration during his sentencing.
Defence counsel Amolat Singh said Kok – who had a good record in polytechnic and during his national service – would have to pay liquidated damages amounting to $50,000 to $60,000 to the NIE for breaching his training contract.
A TRAINEE teacher was sentenced to 15 months in jail yesterday for having sex with two underage girls he met online a few years ago.
One of the girls that Aaron Kok Chun Cheong, 23, had sex with in 2007 was only 12 at that time. He also had sex with a 15-year-old girl in 2008.
This case comes after that of Jonathan Wong, 23, who was on a teaching scholarship at the University of York in Britain.
Wong was convicted of possessing child pornographic videos on his computer and given a suspended six-month sentence. He was also stripped of his scholarship from the Ministry of Education (MOE).
Kok’s offences came to light when the 12-year-old girl was warded at the National University Hospital in July 2008 for stomach pain and vomiting.
She was found to be pregnant, and later told a police officer about her sexual encounters with several men.
Tests of the aborted foetus showed that Kok was not the biological father.
