Counter-terrorism police are leading the investigation into the stabbing of two boys at a north London school, as a 13-year-old suspect is questioned by police on suspicion of attempted murder.
The boy, 13, was held by police after a manhunt was launched for a teenage suspect after the stabbings at Kingsbury High School, Brent on Tuesday.
Police were called to at 12.40pm to the stabbings at the secondary school and the two victims, aged 12 and 13, rushed to hospital where they are understood to be in a “stable” condition.
Speaking at the school, Detective Chief Superintendent Luke Williams said: "The suspect, who we believe to be 13, left the scene following the stabbing.
"After urgent inquiries, our officers arrested him and also recovered a weapon which we believe to have been used in the stabbing.
"The suspect was arrested on suspicion of attempted murder and remains in custody for questioning by our officers."
He said police were "keeping an open mind as to any motivation behind the attack".
"However, due to the surrounding circumstances, the investigation is now being led by officers from counter terrorism policing London, who are working closely with our local officers in response to this incident," Mr Williams continued.
"The investigation has not currently been declared a terrorist incident, and the investigation team will now be working at pace to gather any evidence and to establish the full circumstances of what's happened as quickly as possible."

The headteacher of the school said the incident was “a deeply traumatic event for the whole school community”, in a letter to parents and carers.
Alex Thomas said: “I fully appreciate that this will be very upsetting news to hear and, as you can imagine, this has been a deeply traumatic event for the whole school community.
“The situation is under control, but a live investigation is taking place. We are working closely with the authorities and I will provide further updates as soon as I am able to share confirmed information. Please keep the students and their families in your thoughts.”
Mr Thomas said the Lower School would be closed on Wednesday and students should stay at home, but the Upper School would be open for students in Years 10-13.
On Tuesday evening, pupils were still being spoken to by police officers in one of the school's halls, more than three hours after the usual school day finished - and some were seen leaving in tears.
The father of one pupil said children were obviously “traumatised by what happened in front of them”.
Simon Theodorou, whose daughter attends the school, told the Standard: “I believe the suspect was said to be going after people that he knew” at the “good school”.
Mr Theodorou, who runs a martial arts school, said: “Sadly, one of my pupils here, he did know him, I’m told.”

He told the Metro his daughter told him the attacker had “climbed into the school because they have good security over there. He had to go over a wall.
“Apparently, he pepper-sprayed a classroom. One of the pupils saw what was happening and pulled a fire alarm. He chased him and stabbed them in the neck. I’m not too sure what happened to the other boy.”
He added: “I just ran a seminar on knife mitigation and how to survive a knife injury, it is all too timely.
“To be honest, all youngsters are carrying weapons; they don’t realise what happens when you pull a knife and the repercussions. I’m shaken as well; it could have been my child.”
Mr Theodorou described the boy who apparently pulled the fire alarm as “a hero”. “He did something, he didn’t just let it happen. More children could have been hurt.”
