A 62-year-old primary school teacher who put his hand under his pupils' skirts was yesterday jailed for 21 months.

Three students, aged 10 and 11, had approached the teacher at his desk to ask about their homework.

He lifted their skirts and stroked the girls, the District Court heard. The man had breached the trust not only of his pupils, but of parents and his colleagues, Judge Wong Hing-chung said.
