An expelled student punched a secondary school teacher in Puchong when he was asked why he was hanging around the school, Sin Chew Daily reported.
The 32-year-old teacher needed four stitches to injuries she suffered above her eyes.
The report stated that the teacher had questioned the 16-year-old boy when he and two other teenagers were seen loitering around the compound of the school in Putra Perdana at around 9.50am on Wednesday.
Sepang OCPD Supt Mohd Yusoff Awang said the teenagers were not able to answer when the teacher asked them what they were doing in the school. She was going to alert the disciplinary teacher when the boy punched her.
The boy and his friends have been picked up by the police for further investigations.
