Kingsbury High School to Close After Double Stabbing Leaves Two Pupils Injured

Kingsbury High School in north west London will close part of its campus on Wednesday following a serious stabbing incident that left two pupils injured and sent shockwaves through the local community. The decision was confirmed by school leaders after emergency services were called to the site on Tuesday afternoon.

Police were alerted shortly after 12.40pm when two boys aged 12 and 13 were found with stab injuries inside the school grounds. Both were taken to hospital for treatment and remain under medical care. A 13 year old boy has been arrested on suspicion of attempted murder and a weapon believed to have been used in the attack has been recovered by officers.

In a letter sent to parents and carers, the headteacher of Kingsbury High School described the incident as deeply traumatic for students and staff. He said the school’s thoughts were with the injured pupils and their families and thanked emergency services for their rapid response as well as staff for supporting students calmly during the unfolding situation.

The headteacher confirmed that the Lower School will be closed on Wednesday, with pupils asked to remain at home, while the Upper School will remain open for students in Years 10 to 13. He acknowledged the distress the news would cause and said the school was working closely with authorities while a live investigation continues. Further updates will be shared once confirmed information becomes available.

Police said significant resources have been deployed around the area to reassure students, parents, and local residents. Detective Chief Superintendent Luke Williams, who leads policing in north west London, said officers understand the concern such an incident will cause. He added that their priority is supporting the injured boys and ensuring a thorough investigation is carried out.

Williams praised the actions of paramedics and hospital staff who are treating the injured pupils and said further updates would be provided when appropriate. Officers have maintained a visible presence around the school and nearby streets as part of efforts to maintain safety and gather information.

The incident has also prompted a response from local leaders. A spokesperson for Brent Council said it was horrifying that someone so young could gain access to a weapon capable of causing such harm. The council said it is working alongside the school, police, and community partners to support those affected and to address wider concerns around youth violence.

Parents gathered near the school gates as police activity continued into the afternoon, while pupils were kept under supervision as investigations began. School leaders said students in the Lower School were kept in the playground at the request of police and behaved patiently and respectfully during the disruption.

The incident adds to renewed concern across London about knife crime involving young people, with community leaders urging calm while authorities investigate the circumstances surrounding the attack and how the weapon came onto school premises.
