A teenager who stabbed to death a rival for 'snitching' on him has been cleared of murder but convicted of manslaughter.

Kamal McLeary, 19, of Craven Park Road, Harlesden, plunged a knife into the leg of 20-year-old Anthony Parkes as the pair clashed in a takeaway shop on November 5 last year.

The Old Bailey heard the blade severed the major arteries in Mr Parkes' leg and he quickly bled to death in front of horrified staff and customers

McLeary had branded Mr Parkes a 'rat' for telling police he was involved in a gunpoint robbery that took place in a house in Berkshire.

In his police interview, Mr Parkes admitted being at the house but blamed McLeary and his associates.

The robbery trial in September 2009 ended in a hung jury and both McLeary and Parkes were granted bail until the retrial.

Both men traded insults with each other on a social networking website and the bad feeling culminated when McLeary spotting Mr Parkes entering the Caledonia Chicken Shop in Park Parade, Harlesden.

McLeary admitted responsibility for the death but insisted he only wanted to 'mark' Mr Parkes as a grass by stabbing him in the backside.

No one in the takeaway saw the attack but heard the victim shout 'Aarrghhh.'

Mr Parkes managed to ring 999 before collapsing.

McLeary fled to the nearby home of a 15 year-old friend and was given a change of clothing.

The youth, who can not be named for legal reasons, was accused of taking part in the attack on the basis of joint enterprise but was cleared of both murder and manslaughter by the jury.

He admitted assisting an offender before the trial and will be sentenced with McLeary on June 18.
