A man has been found guilty of killing a 17-year-old boy by stabbing him repeatedly in the head in a street fight outside a primary school.

Amani Lynch, 20, of Vanguard Close, Canning Town, was found guilty of manslaughter at the Old Bailey today (Friday, March 3) following the death of Champion Ganda in Forest Gate in May 2013.

He was also found guilty of wounding with intent to cause grievous bodily harm of Champion's best friend, who was aged 16 at the time.

Lynch will be sentenced on 24 March at the same court.

Devante Clifford, 21 of Lawrence Street, Canning Town, and Marvin Simos, 20 of Claremont Close, North Woolwich, were found not guilty on all counts.

The court heard that on the day of the murder, Lynch had taken a cab to Forest Gate.

As he arrived at the location shortly before 2pm, he spotted Champion, from Romford, and his friend in nearby Ratcliff Road. Immediately Lynch started walking towards them.

Initially the victims ran off and Lynch gave chase, however Champion and his friend turned back and a confrontation began that soon escalated out of control.

Various objects were used including belts, a hammer and a knife and Champion was stabbed 11 times in the head, chest, arms and legs.

He managed to stagger a few yards but collapsed due to the severity of his wounds. Paramedics arrived and carried out emergency surgery in the street but he died from his injuries at 2.45pm.

His friend was stabbed in the legs and chest and required surgery. He has since made a recovery from his injuries.

Lynch made off from the scene in the cab he had kept waiting in St Dunstan's Road.

Lynch, then aged 16, was dropped off in Sophia Road, Canning Town.

Later that afternoon he visited a fast food restaurant in Barking Road where he was overheard boasting about a stabbing and a "bloody" looking knife.

The jury heard there was a history between Lynch and Champion's friend. Both had attended the same college and had been seen fighting each other outside the premises in October 2012.

Lynch was arrested on 14 May 2013 at an associate's flat in Leytonstone. He was charged in December 2015.

Detective Chief Inspector Dave Whellams, from the Met's Homicide and Major Crime Command, said: "This was a brutal, senseless and totally unnecessary attack on a young man on the verge of adulthood, and the ferocity of that attack meant Champion had little chance of survival.

“It has devastated his family and it is only good fortune and the skills of NHS staff that prevented a second murder that day.

"This incident happened right outside a primary school in broad daylight and terrified those who witnessed it. It was the result of petty gang rivalry and ended with tragic consequences."
