A 17-year-old has been found guilty of murdering a schoolboy last year.

Khayri Mclean, 15, was stabbed while making his way home from North Huddersfield Trust School in the West Yorkshire town on 21 September last year, Leeds Crown Court was told.

The 17-year-old, who was 16 at the time, was accused of being one of two teenagers who attacked Khayri after lying in wait for him wearing balaclavas and carrying knives.

Khayri left the school on Woodhouse Hall Road with his friends, where he was met by the defendant and his 15-year-old co-accused, who “charged” towards him aggressively.

The 15-year-old, who has already pleaded guilty to murder, stabbed Khayri in the chest with what proved to be a fatal blow as it went through his ribs and penetrated one of his lungs and heart.

Khayri fell to the floor and was “defenceless on his back” when the defendant, who denied murder, went after him, knife in hand, and stabbed him in his lower leg.

The older boy is on trial because prosecutors say that, although he did not inflict the fatal blow, he acted with his co-accused and they “encouraged and supported each other to carry out the attack”.

The 17-year-old, who cannot be named for legal reasons, claimed he was running with a knife in his hand when he swung at Khayri’s leg because he thought the 15-year-old was trying to “kick me to the floor”.

He told the court he did not realise he had stabbed Khayri in the leg until later.
