A 13-year-old boy suspected of stabbing two boys at a secondary school is a former pupil, police have confirmed.
Police believe the teenager, a British national, went into a first floor classroom at Kingsbury High School, in Brent, north-west London, before spraying a substance towards a pupil.
He was arrested after being seen at a mosque, officers added.
Chief Superintendent Helen Flanagan told reporters: “Having entered the school, he proceeded out to a first floor classroom.
“He entered the classroom, and we believe he sprayed a substance towards a pupil as he entered the door.
“The suspect has then attacked another pupil, a 13-year-old in that classroom, stabbing him, and then the suspect has left, running down the hallway of the school.
“As he is leaving, he then attacked another victim, a 12-year-old, stabbing him before running off and away from the school.”
Counter-terror police have been leading the investigation into Tuesday’s attack at Kingsbury High School in Brent. However, the attack has not been declared a terrorist incident, police said.
Two boys, aged 12 and 13, were taken to hospital in a serious condition after the incident.
Police and ambulance crews were called at around 12.40pm and police said the suspect, who had a weapon, was detained just after 6pm following a search.
In a letter to parents, the school’s head teacher said it was a “deeply traumatic event for the whole school community”. Home Secretary Shabana Mahmood described the attack as “shocking”.
