Three boys who jumped on cars and smashed off wing mirrors after a drunken party in Chessington have been handed youth rehabilitation orders.

A gang went on a rampage through Moor Lane, Frimley Road, Clayton Road, and other nearby streets on April 11 last year.

More than 20 cars were damaged, with a total cost of about £4,000, the court heard.

One witness watched as his bike, worth about £500, was jumped on by youths who left its wheels buckled.

The boys, all aged 17, from Chessington, Epsom and Thames Ditton, who cannot be named for legal reasons, appeared at Kingston Crown Court on Thursday.

Two had pleaded guilty to violent disorder and the third to conspiracy to commit criminal damage.

The boy’s barrister, Benjamin Holt, said his conduct on April 11 last year was “a huge mistake".

The court heard how one of the boys had struggled since the suicide of a close relative.

Mr Holt said: “This young man has not had an easy upbringing. It was the first time he had ever been arrested.

"He has grown up considerably since. He is genuinely ashamed of what he did on that night.”

Now-deputy mayor Councillor Alan Dean was among those affected.

Sentencing the boys, Judge Fergus Mitchell said they had “acted in the most appalling way”.

He said: “Lots of people have got difficulties in their lives. They do not necessarily result in this sort of antisocial behaviour.

“I wonder if you thought for a moment or reflected for a second on the damage you were doing to the lives of other people.

“This sort of mob violence is unacceptable.”

The boys were given two-year youth rehabilitation orders plus two years’ supervision, and ordered to pay £150 costs each.

They will also each carry out 180 hours of unpaid work.

In a previous trial concerning the same events, James Bradley, 18, of Gilders Road, Chessington, and two boys now aged 17 were found not guilty.
