Police have been called into Glen Eden Intermediate School after a student's mother allegedly assaulted a 13-year-old boy.
Principal Maree Stavert said the woman came on to the school grounds at lunchtime on Monday and physically assaulted the boy, who was not her son, in the playground.
She said social media reports that the boy was taken to hospital were not correct and the boy was back at school today.
"He was a bit sore but he was not badly hurt," she said.
"It's not what you expect to happen. But it's just something have to work through with. I haven't seen anything like it."
