A video has been posted to social media of a teacher being punched outside the front gate of a school.
The alleged attack happened at Wilsonton State High in Toowoomba.
The girl who recorded the incident told 7 News the attacker was a former student of the school.
In the video the girl, looking visibly distressed, can be heard saying, “OK, I’m getting out of here.”
The teacher was taken to hospital and received stitches.
“It’s scary to send your kids to school and to think things like this can happen,” one witness said.
Queensland Police and the Education Department are investigating the incident.
