Killer, 15, to be detained for 16 years

A 15-year-old boy who stabbed fellow pupil Harvey Willgoose to death during a school lunch break has been detained for at least 16 years.

- 

Mohammed Umar Khan, who can now be named following a judge’s ruling, took a hunting knife to school and knifed the teenager in the heart in front of horrified children on February 3.

Khan's trial heard how other pupils fled “in fear and panic”, some locking themselves in a school cupboard, after the fatal attack at the All Saints Catholic High School in Sheffield.

He was found guilty of murder in August, with Harvey's sister, Sophie Willgoose, describing the killing as “not just a crime against my brother, it was a crime against all of us who loved him”
