The “brutal” stabbing of a 16-year-old boy “took place near a school” and was witnessed by “many” young people, police have said.

Police were called to reports of a stabbing in Markhouse Road, Walthamstow, at 4.09pm on Friday (May 5).

Kelmscott School Headteacher, Sam Jones, has since confirmed that a 16-year-old boy who subsequently died at the scene was a student at the school.

Police said that the victim’s family are being supported by specially trained officers.

A post-mortem examination found that the teenager had died from a stab wound to the chest.

At this stage in the police investigation no arrests have been made.

Police have now urged members of the public to share any footage they may have of the incident with them.

Detective Chief Inspector Mark Rogers said: “My team is working hard to bring justice for the teenage victim and his family in this case and my heartfelt condolences are with them at this terrible time.

“This is a fast moving investigation and we are aware that this brutal attack took place near a school, and was witnessed by many bystanders and young people.

“My thoughts are with them as they come to terms with seeing such an act of violence unfold and I would ask anyone with footage or images to do the right thing and send them into my team of detectives.

“If you wish to submit images or footage anonymously, please share via Crimestoppers, or you can contact the Major Incident Room where one of my team will be able to take your call. You can also share the images via the Public Portal.

“We also know that there was heavy traffic on Markhouse Road at that time of day and we think there is a strong chance some people will have dash cam footage. Please review what you have and send anything that may assist the investigation without delay.

“A young boy has lost his life and evidence such as this can contribute to securing justice for his family and friends.”
