Teen, 16, stabbed to death at house party after gatecrashers arrived when it was advertised on Instagram
Paramedics performed open-heart surgery on Che Labastide-Wellington after he was attacked in Harrow on November 8
A TEENAGER who knifed a schoolboy to death at a 16-year-old girl's birthday party that was advertised on Instagram faces years behind bars.
Che Labastide-Wellington, 17, was stabbed through the heart as he tried to escape a 'small army' of youths who turned up out the gathering in Harrow in northwest London.
Paramedics performed open-heart surgery on the youngster at the side of the road, but he was pronounced dead at the scene less than an hour later.
A second victim, then aged 16, was also knifed on November 8 last year but survived.
The birthday girl's mother banned booze, drugs, cigarettes from the party in Belvedere Way and insisted everyone on the tightly-controlled guest list was searched before they came in.
But her daughter had posted a flyer on Instagram advertising the bash and trouble flared up when the scores of gatecrashers tried to get in.
Walker Sesay, 19, was among seven men summoned to the party to deal with gatecrashers, but stabbed Che in the chest as violence erupted, the Old Bailey heard.
Sesay and six co-defendants were acquitted of murder by a jury but Sesay along was found guilty of manslaughter.
Calvin Tudor, 22, Marlon Tudor, 23 and Rimmel Williams, 18 were convicted of wounding with intent to cause grievous bodily harm against the 16-year-old, while Omar Afrah, 22 and Ola Onafowokan, 23, were found guilty of conspiracy to commit violent disorder.
Ibrahim Mansaray, 18 and a 17-year-old who cannot be named for legal reasons, walked free after they were acquitted of all of the charges they faced.
Judge Stephen Kramer QC, adjourned sentence until December 6 and told the guilty men: "Be under no illusion in each of your cases, there is a 99.9 per cent certainty there will be a custodial sentence."

During the trial, prosecutor Crispin Aylett QC said: "Last November, a mother agreed that her daughter could hold a party to celebrate her 16th birthday.
"She could not have taken more care, there was to be no alcohol, drugs or cigarettes.
"Everyone who came to the party had know the girl personally, everyone who came through the door had to agree to be searched by the mother and her friends and relatives of hers who had offered to help.
"All the same it ended in disaster.
"Che Labastide-Wellington, a 17-year-old boy, was stabbed to death, his friend, aged 16, was stabbed several times and ended up having a blood transfusion."
The court heard how at the last moment, the daughter had told her mother she was going to post a 'flyer' for her party on Instagram.
Mr Aylett said: "The mother had been unhappy about this but her daughter had assured her it would be alright, anyone who wanted to come to the party would have to send a message to found out the address.
"Nonetheless, the fact that the party was on Instagram did mean that other people found out about it.
"The prosecution allege that the defendants' group split into two in order to surround those who were outside the party,
"It would seem that Che must have stabbed as he ran towards the defendants' group, he was stabbed full-on in the chest.
"Although he was able to break through the group and run into an alleyway with his friend, he soon collapsed, face down on the ground."
"Everyone who came to the party had know the girl personally, everyone who came through the door had to agree to be searched by the mother and her friends and relatives of hers who had offered to help.

"All the same it ended in disaster."
Jurors heard that his 16-year-old friend desperately banged on the door of a house in the street as he fled the group.
Although the owners let him in, a number of his attackers forced their way through the door.
He suffered numerous stab wounds to the arm and legs as he curled up to protect his chest.
The group fled when someone yelled 'Police!'
The defendants were tracked down in the weeks after the attack through a combination of CCTV evidence and mobile phone data, the court heard.
Mr Aylett added: "It is now apparent that each of the seven defendants is said to gave gone to the street of the party now accepts having done so.
"However each of them has denied either having been armed himself or having known that anyone else was armed.
"Each of them has denied having been responsible for the fatal injury to Che Labastide-Wellington or the injuries to the 16-year-old."
