Three teachers - including the headteacher - have been suspended from a Derbyshire secondary school while an investigation is carried out.
Parents said this week they were considering removing their children from Newbold Community School after headteacher Jackie Overton and two other members of staff were removed from the classroom.
One concerned mum who did not want to be named, said: “We haven’t been given enough information. All we know is the head has gone.
“I’m shocked, you don’t expect it and I’m considering taking my son out of the school.”
Another parent added: “We’ve had a letter to say the head is absent. It would be good to find out why.”
The school on Highfield Lane has over 1,000 pupils and over 100 sixth formers.
A spokeswoman for Derbyshire County Council said an investigation was being carried out and it was the role of the school’s governing body to keep parents informed.
She added the headteacher had been suspended and two other teachers had been suspended for unrelated issues.
“None of the suspensions are in connection with safety of children at Newbold School,” she said.
Deputy headteacher at Tupton Hall School, Martin Ebbage, has been appointed as acting head.
A council spokeswoman added: “These actions and the fact an acting headteacher has been appointed already are to ensure the continuing smooth running of the school.”
She could not confirm why the teachers had been suspended.
A spokesman for Newbold School said: “It has been a difficult time for the school but – as parents would expect – we are operating as usual.
“The safety, wellbeing and education of our children are our priorities.
“A new acting headteacher, Martin Ebbage joins us on Monday, December 3.”
