Boy, 15, dies after being stabbed at a school in Sheffield

A 15-year-old boy has died after being stabbed at a school in Sheffield.

Police were called to All Saints Catholic High School on Granville Road at 12.17pm on Monday after reports of a stabbing.

South Yorkshire Police said the boy "suffered serious injuries and despite the best efforts of the ambulance service, he sadly died a short time later". The victim's family has been informed.

A 15-year-old boy has been detained on suspicion of murder and remains in custody.

Speaking outside the force's headquarters, Assistant Chief Constable Lindsey Butterfield 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."

ACC Butterfield said the force's officers are "working at pace to build a full picture of how this tragedy has unfolded".

"We know that what has happened will cause significant distress and concern," she said.

"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."

Prime Minister Sir Keir Starmer said his thoughts are with the family of the 15-year-old boy, adding the "whole country" will "mourn with them".

"Obviously there will be an investigation, but I think at this point I simply speak for the country, to the individuals affected, to the family in particular, but everybody impacted by this awful situation - a young boy has gone to school and hasn't returned home," he said.

'Second school lockdown in a week'

Police have taped off a section inside one of the school buildings as members of the public laid tributes with balloons, flowers and messages at the school gates.

It is the second time All Saints Catholic High School has gone into lockdown in a week, the PA news agency reported.

Headteacher Sean Pender sent a message to parents on 29 January, saying: "The reason for the lockdown was due to threatening behaviour between a small number of students where threats were made of physical violence."

A 2023 Ofsted report rated the school, which had 1,398 pupils at the time, as "good".

Inspectors found that most pupils behaved well and "a strong ethos of warmth and respect pervades this school".

'Avoid speculation' - police

Meanwhile, ACC Butterfield warned the public to avoid sharing distressing content related to the stabbing on social media.

She said: "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."

Granville Road was closed from the tram stop to Fitzwalter Road, and police asked the public to avoid the area while emergency services carried out their work.

Education secretary Bridget Phillipson said she was "devastated" to hear about the stabbing.

"My heart goes out to his family, friends and the entire school community at this distressing time," she said.

"We are in contact with the school and council to offer support. Investigations are now under way."

'Serious questions need answering'

Sheffield Heeley MP Louise Haigh has said "serious questions will have to be answered" after the "horrific news" of the fatal stabbing.

"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."

South Yorkshire's mayor, Oliver Coppard, 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.

"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."
