SINGAPORE - A female teacher in Singapore who had sex with a 15-year-old student was jailed for 10 months Monday, a court spokesman said.

The woman's identity had been withheld to protect the victim, said the spokesman, who confirmed that District Judge Sarjit Singh handed down the sentence, but gave no further details.

Now unemployed, the 32-year-old woman earlier pleaded guilty to having sex with a minor under the age of 16, The Straits Times website reported.

The friendship between the teacher and boy began when he was a 14-year-old Grade Six pupil and joined an overseas school trip which she led, the report said.

They later had sex, when he was 15, after the boy said he loved the woman who had declared him her godson, it said. By then, the boy had moved on to a secondary school.

They had sex five more times but when she tried to end the affair the boy threatened to kill her, leading her to contact police, The Straits Times said.

The newspaper added that Judge Singh said the case involved a serious breach of trust.

The woman could have been jailed for up to 10 years and fined as well.

She wept as she was led away to serve her sentence, 938Live radio reported.
