Det Ch Insp Andy Knowles, the lead officer on the case, tells the BBC: “Something that became prevalent during this trial was Khan’s misguided belief that carrying a knife would make him safer, or that it would grant him some sort of status."

“But, in reality," he adds, "that knife had devastating consequences, not just for Harvey and his family, but also for Khan himself."

Det Ch Insp Knowles has thanked the Willgoose family for the "courage they have shown throughout".

He says things "would almost certainly have been very different" had a knife not been involved in the confrontation between Harvey and Khan on 3 February.

“If you think someone you know and love is carrying a knife, or feeling under pressure to carry one, please make it clear to them that a knife is not what they think it is," he adds.

He encourages people to have "open and honest" conversations about carrying weapons.

Labour MP Louise Haigh, whose Sheffield Heeley constituency includes All Saints Catholic High School where Harvey was fatally stabbed, says his murder has "devastated his family, friends and our community".

Ms Haigh (pictured) says she hopes Mohammed Umar Khan's life sentence today for the 15-year-old's murder "brings some measure of justice".

However, it can never undo the unbearable loss Harvey’s loved ones have suffered," she says.

“What matters now is that Harvey’s death marks a moment of real change.

"A child safeguarding review is under way to examine the circumstances that led to his murder and to establish if it was remotely preventable.

"We cannot allow its findings to be ignored, as so many have been before.

"I will hold the government and all relevant organisations accountable to ensure this review delivers meaningful reform, not more words on paper.

"But, for today, my thoughts are only with Harvey's family and all those who loved him."

South Yorkshire's Deputy Mayor for Policing and Crime has described today's sentencing of Mohammed Umar Khan for the murder of Harvey Willgoose as "a difficult moment for our region".

In a statement, Kilvinder Vigurs says: "This tragedy is a stark reminder of the urgent need to tackle violence at its roots.

"This is a priority for us and is a particular focus as set out in the Mayor’s Police and Crime Plan. Knife crime is not just a policing issue, it’s a societal one."

She goes on to pay tribute to the "strength and dignity" of Harvey's parents, Caroline and Mark.

"Their courage reminds us why we must do more to protect our children from the threat of knife crime," she says.

Harvey’s mother, Caroline Willgoose, says she feels "like a big weight has been lifted off my shoulders" following Khan's sentencing this afternoon.

Speaking outside Sheffield Crown Court, she says she is glad the minimum term was raised above the legal minimum, which would have been 15 years.

Mrs Willgoose says Harvey and his grandfather, who died last week, had been "best friends" and had been building a summer house together.

"My dad has been having cancer treatment through the trial and he just couldn’t hold on anymore," she says.

“I do feel that he is with him."

Mrs Willgoose says she is glad Harvey's grandfather got to see the knife arches being put into some schools as a result of the family’s campaigning.

During the trial at Sheffield Crown Court, the jury was played CCTV from the day of Harvey's stabbing.

Part of the footage shows Mohammed Umar Khan, 15, pushing 15-year-old Harvey in a corridor at All Saints Catholic High School in Sheffield on 3 February.

Khan is later seen wielding the murder weapon in the school cafeteria after the fatal stabbing.

In a statement issued following the sentencing hearing, a spokesperson for All Saints Catholic High School in Sheffield has said Harvey Willgoose (pictured) is "dearly missed every day by the whole school community".

The statement reads: "Our thoughts are first and foremost with Harvey's family, loved ones and friends.

"We cannot begin to imagine the depth of their loss and our deepest sympathies go out to them today and every day.

"This tragedy has also deeply affected our community and we continue to do what we can to support all those impacted.

"Harvey was a popular, energetic and fun-loving pupil who is dearly missed every day by the whole school community."

The school says it is "engaging fully" with a number of ongoing investigations "aimed at answering key questions about Harvey's tragic death".

"We will continue to work closely with these partners and cooperate fully with these investigations," the statement adds.

This is the moment Mrs Justice Ellenbogen handed Mohammed Umar Khan a life sentence for the murder of 15-year-old Harvey Willgoose.

The sentencing took place in Court 1 of Sheffield Crown Court just moments ago:

Harvey, also 15, was stabbed by Khan at All Saints Catholic High School in Sheffield on 3 February this year.

Mrs Justice Ellenbogen told Khan the life sentence with a minimum term of 16 years would be minus the time he had already spent on remand.

He showed no emotion as his sentence was passed in Court 1 at Sheffield Crown Court.

"For the murder of Harvey Willgoose, I pass the only sentence which the law allows me to pass," the judge says.

"You will remain in secure custody until the parole board decides you may be considered for release," she tells Mohammed Umar Khan.

The minimum term is 16 years, inclusive of the period he has already spent in custody.

"There is no guarantee you will be released at the end of that time," Mrs Justice Ellenbogen says.

Khan nods as she tells him this.

Mohammed Umar Khan has been handed a life sentence with a 16-year minimum term for the murder of Harvey Willgoose, minus the time he has spent on remand.

Mrs Justice Ellenbogen says the starting point for a minimum term, given Khan's age, is 17 years in custody.

This will then be adjusted to take account of the aggravating and mitigating factors in the case.

She says there was not a "great deal of planning or premeditation" in his killing of Harvey Willgoose.

"I am sure that by the science lesson, should the need as you saw it arise, you would use your knife on Harvey. The knife you had brought was, in your words, scary."

She notes the presence of pupils and teachers and the fact it took place on school premises as aggravating factors.

"The fact you stabbed Harvey twice in his chest indicates the high degree of bodily harm you intended to cause him," she says.

"Whilst your premeditation was not long-standing, it cannot be said it was lacking altogether."

Mrs Justice Ellenbogen tells Khan how the sentence for murder is fixed by law.

"I must sentence you to detention during His Majesty's Pleasure," she tells him.

"That means a life sentence in a secure place, imposed on a person who commits the offence of murder."

Khan appears to nod slightly.

She says there will be a minimum term and tells him: "You will remain on licence for the rest of your life."

She describes the sentencing guidelines she has followed while deciding a minimum term.

The judge tells Khan: "You said you had been carrying a knife for protection, and had been followed over the weekend, and were scared of being jumped outside school."

He had photos of knives from April 2024, and from at least September 2024, had searched online for terms like "zombie killer knife", she says.

"Throughout the trial you sought to minimise the extent of your interest [in weapons], and sought to explain how images of them had come to be on your phone which were, put simply, not believable", Mrs Justice Ellenbogen says.

The judge describes the "severe" force used by Khan to stab Harvey.

She notes it had cut through "the full thickness" of one of his ribs.

"Harvey ran towards you and you were seen to have advanced again, dancing on your feet and waving the knife," she tells Khan.

About 49 seconds later, Harvey collapsed. Khan then moved into the dining room.

"In an act of considerable bravery, Mr [Morgan] Davis put out his hand and took the knife from you," the judge tells Khan.

"While waiting for the arrival of the police you said, 'I'm not right in the head, my mum doesn't look after me right', and said you had stabbed him once or twice."

The judge tells Khan: "At 12:10, the lunch break began, you made your way to the dining area.

"In the dining area, you spoke to another boy who later described the conversation he had had with you at that time.

"He said you had been mad at [Harvey] and you suddenly talked about a knife. His evidence is that he told you to give him the knife 'before you did something stupid'.

"I cannot be sure that you had seen and made a beeline for Harvey," Mrs Justice Ellenbogen tells Khan.

There was some interaction between the boys that morning at school, which the judge says she is "satisfied was good natured".

The pair had been shadow-boxing and lightly pushed each other around, she explains.

Later, in a busy corridor, they had a similar interaction.

But a short while later, in a science lesson, the boys had squared up genuinely, the judge says.

"It seems words were exchanged between you and a teacher physically intervened," Mrs Justice Ellenbogen adds.

On Harvey's way to see a teacher, Claire Staniforth, another teacher, overheard him saying "something was going to happen".

The judge is detailing the facts of the case.

She tells Khan how he and Harvey Willgoose had become involved in an argument the weekend before the Monday of the fatal stabbing.

Each of the boys had been standing up for their own friends.

Harvey and Khan had initially been friends, the judge says.

On the morning of Harvey's death, the pair had spoken over messages about whether there was "beef" between them.

Mrs Justice Ellenbogen says Khan has caused "unbearable pain and grief" through his "senseless" killing of Harvey Willgoose.

"Harvey's family is haunted by the CCTV footage of the events of that day and is exhausted by the trauma," she tells him.

"It is clear Harvey was a popular pupil who students and teachers held in affection. Their lives, too, have been blighted by your actions."

Khan looks at the judge with a neutral expression, and occasionally glances around the room.

The judge, Mrs Justice Ellenbogen has returned and addresses Mohammed Umar Khan.

"On 3 February 2025, in the courtyard at the school where you were both pupils, you fatally stabbed Harvey Willgoose in his heart," she tells him.

She will sentence Khan for the offences of murder and possessing a blade on school premises.
