A 14-year-old schoolboy has been arrested in connection with the death of a 17-year-old guest who was stabbed outside a 16th birthday party in Kenton.

The youth is being held on suspicion of possession of an offensive weapon following the death of Che Labastide-Wellington.

Che, who lived in Harrow, was stabbed in the chest in Belvedere Way, on Sunday morning at around 12.30am.

A 16-year-old boy was also knifed too.

He is in hospital in a stable condition.

Shortly before Che was stabbed a group of youths had tried to gatecrash the party which resulted in a clash.

Che, who was an invited guest and had not been involved in the clash, was stabbed during a second altercation in an alleyway outside the party.

He died an hour later at the scene.

The detective who is leading the murder hunt is appealing for witnesses to either clashes to come forward.

Detective Chief Inspector Chris Jones said: “Che had been invited to attend a 16th birthday party at a house in Belvedere Way. This appears to have been a well-run event with appropriate adults in attendance. There were no reports of any trouble inside the venue but clearly there has been a violent attack outside.

“At this stage we are continuing work to establish what the motive for this attack was.

“There were a number of people present outside the venue when this incident took place and I would appeal to anyone who witnessed the attack on Che, or the events leading up to this, to contact police.”

The 14-year-old is currently in police custody.

Two boys age 15 and 16 who were arrested on suspicion of murder have both been bailed to a date in mid-December.

Anyone with information is asked to call the incident room on 020 8345 3734 or Crimestoppers anonymously on 0800 555 111.
