Two teens who stabbed Khayri Mclean, 15, to death are jailed for life trends now

The mother of a 15-year-old boy murdered by two teenagers in a 'gang-related' knife attack outside his school told a court today: 'This violence has to stop.'

In a heart-rending statement read to Leeds Crown Court, Charlie McLean said she would never get over the senseless killing of her son Khayri by two 'cowards.'

She said: 'I would gladly give my life for him, to have him back, but that's impossible.

'I ask myself what has this achieved? What has my son died for? I have lost my child and other parents have lost their two children who did this.

'Nobody has won. This violence has to stop and carrying weapons has to stop.'

Ms McLean described how she rushed to the scene and watched helplessly as paramedics tried in vain to save her son's life.

'The fear he would have had when he realised he had been stabbed and was bleeding to death will stay with me forever,' she said.

Two cousins, aged 15 and 16 at the time, will be given a life sentence for murder later today.

In a carefully planned ambush in Huddersfield, West Yorkshire, last September, the teenagers went armed with large knives, dressed in black and wearing balaclavas.

They pounced on the teenager, with one shouting 'yo Khayri' as he walked home from school with friends.

The 15-year-old attacker, who admitted murder, was seen by witnesses to jump in the air before 'swinging his arm' and plunging a knife with a 12-inch blade into Khayri's chest.

The attacker, who admitted being part of a rival gang, was said to be under the influence of a drugs at the time. The fatal blow pierced his victim's heart and proved fatal.

Moments later the older attacker – now aged 17 – followed up by stabbing Khayri in the leg as he tried to also target his chest.
