A primary school teacher has been suspended from teaching for slapping students and ordering them to kneel down as punishments. North Point Government Primary School principal Tang Oi-lin said parents of a Primary Three student complained that their son was slapped on the face on Tuesday. 'We then launched an investigation, talked with his classmates and other students and found that the case was serious,' Ms Tang said. More parents complained and, as well as slapping students, the teacher was found to be punishing them by asking them to go down on their knees, the principal added. Ms Tang did not say why the teacher punished the students in class. 'We have to control our emotions,' she said. 'It is very inappropriate for any teacher to punish students in these ways, whatever happened.' The teacher, in his 40s, has been teaching for more than 10 years and has worked at the North Point school for five years, teaching Chinese language and information technology. 'We have informed the Education Bureau over the incident and we are now investigating the case with them. Disciplinary action will be taken later, after the investigation,' Ms Tang said. The teacher, meanwhile, was asked not to teach but to work on the school's computer database and to help in the school's library. 'We have also informed all students about the case. We told them that a teacher did something wrong,' Ms Tang said. Secretary for Education Michael Suen Ming-yeung said: 'Everyone will feel upset by the incident. It should not happen.'
