A 21-year-old man is being held on suspicion of killing Che Labastide-Wellington who was stabbed to death in Belvedere Way, on Sunday morning at around 12.30am.

Che, who lived in Harrow, was knifed in the chest in an alleyway next to the event alongside a 16-year-old boy who survived his injuries.

He is currently in hospital in a stable condition.

Yesterday a 14-year-old was arrested on suspicion of possessing an offensive weapon. He has been bailed to return to a police station in January.

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

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.”

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

A crowd fundraising page has been set up in Che’s memory on the gofund me website.
