A boy has been arrested after a teenage girl was stabbed at a school near Norwich.
Officers were called to Thorpe St Andrew School, Laundry Lane, Thorpe St Andrew, at 10.24am on Wednesday following reports a girl had been stabbed.
A 16-year-old boy has been arrested on suspicion of causing grievous bodily harm with intent, Norfolk Police said.
The boy has been taken to Wymondham police investigation centre for questioning, the force added.
The victim has been taken to hospital with minor injuries.
Emergency services including fire and ambulance crews were at the scene.
Armed police officers were also at the school, reported the Eastern Daily Press.
The school went "into lockdown" and children remained in their "classroom with their teacher".
Owen Jenkins, the chief executive of Broad Horizons Education Trust, which runs the school, said: "We have clear procedures in place and our staff acted swiftly, with the whole school going into lockdown with children staying in their classroom with their teacher.
"One of our students was injured and is now being treated in hospital for minor injuries.
"This has obviously been a distressing experience for our whole community and our focus now is on making sure all students feel supported as we begin to understand what happened."
Norwich North MP Alice Macdonald wrote on social media: "Reports from Thorpe St Andrew School are incredibly serious and deeply alarming.
"Immediately, we need to give the police time to ensure that everyone at the school is safe.
"My thoughts are with all of them and their families, especially the victim who has been taken to hospital."

The incident is not believed to be linked to a hate crime reported at the same school last week, police added.
It followed reports of allegations of antisemitic chanting during a football match involving a Jewish school.
