A teenager who murdered a student during a row over throwing conkers in north London has had his sentence increased by the Court of Appeal.

Ochaine Williams, 16, who can now be named, was in court to hear three judges raise his minimum term from 10-and-a-half years to 12 years.

Steven Grisales, 21, was stabbed when he challenged youths throwing conkers in their husks at him.

He died the day after the attack in College Close, Edmonton, in 2011.

Williams, of Victoria Road, Edmonton, north London, was 15 at the time of the killing.

He denied murder, blaming another youth, but was found guilty at the Old Bailey in May.

Judge Richard Marks ordered him to be detained with a minimum term of 10-and-a-half years.

Submissions then made on behalf of Attorney General Dominic Grieve argued the original minimum term was "unduly lenient" and failed adequately to reflect the gravity of the offence and "public concern over offences of this nature".

Increasing the sentence on Tuesday, Lady Justice Hallett said: "This was yet another example of mindless violence on the streets of London.

"Mr Grisales, an innocent young man, has died simply because he dared to stand up to bullies."

The court heard Williams had made an application for leave to appeal against his conviction.

An order suspending publication of his name pending an appeal was lifted by the three appeal judges following a media application.
