Two teenage killers from High Wycombe who were jailed over a brutal stab attack on an 18-year-old could have their prison sentences extended.

The victim, Slough teen Wa-ays Dhaye, was ambushed, repeatedly stabbed and left for dead in a brutal attack yards away from his home on August 31 last year, with 19-year-old Khianni Gordon jailed for murder after a five-week trial.

His accomplices, High Wycombe pair Kaneel Huggins, also 19, and Anton Clarke, 18, were found guilty of manslaughter.

In April, Gordon was jailed for life, while Huggins was locked up for 10 years and Clarke for nine.

But lawyers for the Attorney General, Jeremy Wright QC, are now urging top judges to increase the sentences handed to Huggins and Clarke.

Appearing today at the Court of Appeal, in London, they argued the sentences were "unduly lenient" for such a serious crime.

The court was also asked to consider appeals by Gordon against his murder conviction and, if that fails, his 19-year minimum sentence.

Lady Justice Sharp, Mrs Justice Elisabeth Laing and Mr Justice Knowles reserved their decision on the case to a later date.

During the murder trial earlier this year, jurors heard the killing resulted from social media taunts – reportedly about the tragic death of Marlow boy Kyrece Francis who died while swimming in the River Thames - and a “minimal” altercation during Notting Hill Carnival earlier that day.

Armed with knives, the trio then hunted Wa-ays down away from his friends before stalking him through the streets and carrying out the attack close to his home.

Wa-ays suffered multiple stab wounds including one which severed his main artery.

All three defendants travelled back to High Wycombe and two days later Gordon and Huggins took the car and burnt it out in Marlow, destroying evidence.

The trio blamed the attack on the cousin of 13-year-old Kyrece, but the jury did not believe their story and instead found them guilty of the crime.

At the time of the sentencing, detective chief inspector Kevin Brown said: “A family has lost their loved one in an incredibly devastating and traumatic way.

"There is no punishment that will change what has happened, or bring Wa-ays back, and I do not expect the sentences to help ease their pain.

"I can only hope that the knowledge that the people who killed Wa-ays are behind bars will give his family some comfort.”
