The man, from Owlsmoor Road, was attacked at around 11.50pm last Friday after trying to stop a group of 15 to 20 youths from tearing down his garden wall.

The youths were pulling bricks from the wall when he asked them to move on. They became abusive and three of them attacked him, punching him in the face.

Bricks from the wall were thrown over the fence causing damage to his car, and the rear windscreen wiper was ripped off.

It is believed the youths were local and had been out in Crowthorne earlier in the evening before returning to Owlsmoor. The group was made up of boys and girls, though it was only the boys who caused the damage and attacked the man.

Sgt Jackie Phillips said: "They showed no respect for this man, his family or his property."

The attack comes just two weeks after a major new crackdown on youth crime was launched in Crowthorne and Sandhurst.

Operation Lancaster was set up after police were plagued by reports of petty crime from residents each weekend.

It is hoped the scheme, which is based on giving townsfolk direct access to an officer via a dedicated mobile phone number, will reduce youth disorder and give quicker response times.

Any resident who wants to report a youth-related crime between 7.30pm and midnight on Saturdays and Sundays, can phone and speak to a Crowthorne or Sandhurst officer directly.

The service cuts out the middleman — a common complaint from people reporting crimes in the area — and guarantees as fast a response time as possible.

Last Saturday, four cans of cider were confiscated from a 15-year-old boy in College Town although they were returned to his mother after he said she had bought them for him.

There was one call reporting noise and loud music coming from Bigshotte Park which turned out to be a private party from a house on the edge of the park.

Police are keen to hear from anyone who may have information as to the identity of the youths. Anyone who can help should contact PC Paul Musson on (01344) 823456 or Crimestoppers on (0800) 555 111.
