A 15-year-old boy who murdered teenager Harvey Willgoose, 15, at All Saints Catholic High School has been named as Mohammed Umar Khan, a judge has ruled.
Young students ran away 'in fear and panic' following the fatal attack at the school in Sheffield on 3 February.
Khan - who was in year nine when he murdered Willgoose - was found guilty of murder in August and sentenced to life in prison with a minimum of 16 years judge Mrs Justice Ellenbogen today (22 October).
In court today, the judge agreed to lift an order banning his identification following applications from a number of media organisations.
"I am satisfied that the balance of the important competing interests in this case tips in favour of identifying Boy A," the judge said.
"I am satisfied it is in the interests of justice to do so.
"The fact that he is young isn't in the interests of restricting reporting."
The 15-year-old who murdered Harvey Willgoose has been named as Mohammed Umar Khan (South Yorkshire Police) CCTV footage displayed to the jury showed how Khan stabbed Harvey twice, cutting through one of his ribs and piercing his heart during his lunch break.
Jurors at Sheffield Crown Court heard how Khan told headteacher Sean Pender after the stabbing: “I’m not right in the head. My mum doesn’t look after me right.”
Morgan Davis, the assistant head, took the knife off the defendant and heard him say 'you know I can’t control it', which the teacher took to be a reference to his anger issues, given previous incidents of violent behaviour at school.
Harvey Willgoose was stabbed to death during his lunch break (Family handout) The jury was told how Harvey and Khan fell out following an incident in the school five days before the fatal stabbing, on January 29.
On that day, Khan tried to intervene in an altercation involving two other boys and had to be restrained by a teacher.
When he claimed one of these boys had a knife, a lockdown was declared and police were called, although no weapon was found.
The judge told Sheffield Crown Court today that Khan will be sentenced to a 'significant minimum term' of imprisonment, calling the murder 'a serious crime carried out by one pupil against another on school property'.
She reiterated that the 'public will wish to know the identity of those who commit such serious offences', and that his age was not enough of a reason for him to remain anonymous.
Just days after the fatal stabbing, Harvey's family said he would be 'forever known for being a caring, loving and funny young man'.
"We have lost a beloved son, brother, grandson, cousin, nephew and, most importantly, a best friend to all," they said.
The CEO of the academy trust said Harvey was an 'immensely popular young man with his fellow students and teachers alike'.
