Mohammed Umar Khan stabbed fellow 15-year-old at All Saints Catholic high school in Sheffield in February

The teenager convicted of the murder of Harvey Willgoose has been named and sentenced to life with a minimum of 16 years in prison.

Mohammed Umar Khan, also 15, was handed the sentence by the judge, Naomi Ellenbogen, on Wednesday after being found guilty in August of stabbing Harvey in a Sheffield secondary school.

Mohammed’s identity had not been reported previously due to his age but this order was lifted by Mrs Justice Ellenbogen following applications from a number of media organisations. She said his age alone did not justify maintaining his anonymity and that the “public will wish to know the identity of those who commit such serious offences”.

Addressing Mohammed, who attended court in a black hoodie, Ellenbogen rejected claims that he had acted in self-defence, saying that he had “blighted” the lives of anyone who knew Harvey, and had acted out of “the hurt and anger at what you considered to be his betrayal of your friendship”.
