A 14-year-old boy has been arrested on suspicion of attempted murder after a teacher was stabbed in the stomach in a classroom.
The teenager was detained in Bradford after police issued an appeal for information about the pupil’s whereabouts.
Video has emerged of the moment the boy was arrested in the city’s Centenary Square.
Police say 50-year-old teacher Vincent Uzomah, from Leeds, was stabbed once during a science class just before 9am at Bradford’s Dixons Kings Academy.
Detective Superintendent Simon Atkinson, of West Yorkshire Police, described the attack as an “isolated incident”, adding that it was witnessed by a number of pupils.
He said: “[Mr Uzomah’s] injuries are not believed to be life-threatening and his condition is currently described as stable. His family are with him at his bedside.
“There were a number of pupils who witnessed this incident, which took place in a classroom, and they are currently liaising with our specially trained officers who are obviously supporting them at this difficult time.
“I would like to reassure residents and staff that all necessary resources are being deployed to investigate this ongoing and clearly serious incident.”
Neil Miley, principal at Dixons Kings Academy, said the school’s thoughts are with the teacher and his family.
“We’re working closely with the police and our main priority at this moment is the safety and wellbeing of our students and staff community,” he said.
“All students are safe and calm and have responded with tremendous maturity during a very difficult time for our school.”
Mr Miley added that counsellors were at the school to help pupils who need support.
Dixons Kings Academy was formerly the Kings Science Academy and joined the Dixons academy trust earlier this year.
Kings Science Academy, which was visited by Prime Minister David Cameron in 2012, was one of the first 24 free schools to open in 2011.
The school was rated as requiring improvement by Ofsted following an inspection last December.
