A teenager has been sentenced to seven years in jail after being found guilty of being part of a violent gang attack in New Malden which left a victim in a coma.

William Hutson, 16, who lives in Mitcham Road, Croydon, groaned as the judge delivered the sentence at the Old Bailey this morning.

In January he was found guilty of causing grievous bodily harm with intent and theft in Blagdon Park last April.

He was found not guilty of attempted murder.
