Hong Kong - A Hong Kong teacher has been charged with having sex with a primary school pupil and keeping pictures of the encounters on his computer, a court report said Friday.

Primary school teacher Chung Wing-kwok faces one count of possessing child pornography and one of having unlawful sexual intercourse with a girl under 16.

The 32-year-old is also accused of indecently assaulting a second girl, aged 11, during extra-curricular activities at the school, said the report in the South China Morning Post.

The prosecution claims the offences, which allegedly occurred between December 2007 and this month, came to light when the second victim reported an incident when Chung kissed her to the school.

During a subsequent search of his home, police found images of sexual encounters with the other girl, now 15, which included sexual intercourse, oral sex and photographs of the girl naked.

He appeared in court Thursday, was remanded in custody and the case was adjourned until a later date. (dpa)
