A 13-year old boy on an alcohol-fuelled spree caused hundreds-of-pounds-worth of damage to cars parked in a city street.

The teenager "thought it would be a laugh" to throw stones at car windows -- one woman found a rock inside her car after the incident.

"There was some forensic evidence, DNA was taken from blood found at the scene," prosecutor Angela Sassoli told Ely Youth Court on Thursday.

"When the teenager was spoken to by police he admitted damaging four vehicles that day."

The schoolboy, who cannot be named due to legal reasons, admitted damaging a Toyota Corolla parked in New Barns Avenue in Ely on December 14, and asked for a total of seven similar offences to be taken into consideration.

When interviewed by police, the boy told police he had been drinking alcohol before he caused damage to four cars on December 14.

"He said that looking back, he felt sick because of his actions," added Mrs Sassoli. "The police think someone else was involved, but he will not name them."

At a later date, the youngster told police about four more cars that he damaged between December 20 and 31.

"He does knock around with older boys and as a result finds himself in trouble," said solicitor Jacqui Baldwin. "He suffers from low esteem, and when older boys tell him to do something he does it, because that increases his self esteem. Other boys use him to do their dirty work."

Ms Baldwin said the boy may not have thrown stones at all the damaged cars, but had "taken the rap" for everything.

After the boy apologised for his behaviour, he was ordered to pay �262 worth of compensation. The court gave him a two month electronic tagging order, keeping him at home between 7pm and 7am. An action plan imposed on the youngster will include 24 hours of work and an appointment with a psychologist.
