A Nigerian teenager has been jailed on his 18th birthday for murdering a child in the street in UK.

Months before the ‘brutal and cowardly’ attack in which 15-year-old Kyron Webb was knifed in the heart and back, Michael Idehen rapped about ‘cheffing’ – a slang term for stabbing – in a YouTube video.

The youngster’s life was taken following an ‘inconsequential disagreement’, the court heard. Idehen claimed the spat started after he made ‘derogatory’ comments about a rap group on Snapchat – and that Kyron threatened to stab him.

He was jailed on Friday – his 18th birthday – having pleaded guilty to murder at an earlier hearing. Harrowing CCTV footage showed him plunging a knife into his rival’s heart in Moston, Manchester, in October last year.

He was jailed for 15 years.

Sentencing, Judge David Stockdale QC said:

“Kyron had done nothing to justify, excuse or explain the brutal and cowardly attack on him.

“He offered his attackers no violence nor any threat of violence at all.

“This case provides yet another example of the catastrophic consequences that follow when knives are carried and used as weapons on the street.

“The life of a happy and healthy 15-year-old was taken away, leaving his parents and his wider family devastated.

“When those who carry knives on the streets of Manchester come before the courts, they will receive little sympathy.”
