A teenager has died following a stabbing at a school in Sheffield earlier today, police confirmed in a major update this afternoon. South Yorkshire Police raced to the scene of a lockdown at All Saints Catholic High School earlier this afternoon following reports a teenage pupil was stabbed at the campus on Granville Road. The service initially reported that 15-year-old boy was injured in the incident, but confirmed in a tragic update this afternoon that the died "a short time later".

Police responding to the incident have arrested one 15-year-old on suspicion of murder, Assistant Chief Constable Lindsey Butterfield told reporters during a conference today after suffering "serious injuries". She said: "It is with great sadness that I share with you today, a teenager has died following the stabbing at a Sheffield school earlier today, our thoughts are with the family of the boy, his friends and the whole school community.".

"At 12.17pm, emergency services were called to All Saints Catholic High School on Granville Road. The victim, a 15-year-old boy, suffered serious injuries and despite the best efforts of the ambulance service, he sadly died a short time later. A 15-year-old boy has been arrested on suspicion of murder and remains in our custody at this time. "We know that what has happened will cause significant distress and concern. I would like to reassure you that our officers will remain on scene and in the local area to offer reassurance to parents, staff and local residents as our investigation continues. Although we are in the early stages of our inquiries, we are working at pace to build a full picture of how this tragedy has unfolded.".

"We urge you to be mindful that there are loved ones at the centre of this and they are grieving the profound loss of a teenage boy in the most devastating of circumstances. We would therefore ask you to avoid speculation and the sharing of online content which could be distressing to them and detrimental to our investigation. "We urge anyone with any information that they believe can assist us to get in touch." The incident prompted a response from Prime Minister Sir Keir Starmer, who said the "whole country" would want to reach out to the teen's family, and said an investigation will take place.

He said: "The terrible stabbing in Sheffield, is one where I think the whole country would want to reach out to the family, to the friends, to the school, the entire community in their grief and mourn with them. Obviously there'll be an investigation, but I think at this point I'll simply speak on the country's behalf to the individuals affected and to the family in particular for everybody impacted by this awful situation. A young boy has gone to school and hasn't returned home so my first thoughts as Prime Minister and as a father are with the family.".

The latest victim of Britain's knife crime epidemic "went to school like thousands of others and will never come home", the area's mayor said today. Oliver Coppard, the mayor for South Yorkshire who has Police and Crime Commissioner responsibilities, said: “This morning a teenage boy went to school like thousands of others across South Yorkshire but won’t come home.". "A young man who was a member of our community, with his whole life ahead of him. My love, my thoughts and my prayers are with his family and friends and the whole community of All Saints Catholic High School. The vast majority of our young people don’t carry knives, but one incidence of knife crime is one too many, because when we do see knife crime happen all too often the consequences are utterly devastating, as they have been today.

"I have spoken to the Chief Constable and offered her my full support as she carries out her investigation and continues to do everything she can to prioritise tackling knife crime across South Yorkshire.” A local youth, 18, who has friends at the school claimed the incident came after the two pupils had sent each other menacing messages. The teen said: “I’ve heard it happened after they were sending threatening text messages. The boy got stabbed three times and was carried in a stretcher. I live locally, there was an incident a few days ago but I’ve not heard of anything else here. The latest incident came after after the school was reportedly placed into lockdown on January 29 over "threats of violence" between a "small number of students.".

Sheffield Heeley MP Louise Haigh has said “serious question will have to be answered” after the fatal stabbing. Posting on Facebook, she said: "Horrific news that the young pupil from All Saints High School has died. All my thoughts are with his family and friends, and the entire community at All Saints.". "A teenager is in custody and South Yorkshire Police have assured parents that there is no ongoing risk at the school. A criminal investigation will now obviously take place, but serious questions will have to be answered about how this could have happened and I will be working with the school, the police and the council to make sure they are.".
