A broken wall is supplying vandals with ammunition to pelt a Worthing school with bricks, according to its headteacher.

Three large windows were smashed at Durrington Middle School during the latest attack.

Changing rooms at the school in Salvington Road were also set alight but the small blaze burnt itself out.

The vandal attacks, discovered on Saturday and Sunday morning, will cost more than £1,000 to repair.

Head Bob Pavard said he was "horrified and disappointed" by the damage.

He said the bricks used were from a broken wall near the school and two windows had been smashed during a similar incident a week before.

Mr Pavard said: "We found 42 bits of bricks in the school grounds. There were only three windows broken but there could have been a lot more.

"On Sunday we found somebody had broken into our changing rooms and started a fire in a paper dispenser.

"The windows will cost £300 to £400 and the changing rooms will have to be redecorated because of the smoke."

Classes were disrupted yesterday while workmen replaced the windows.

Mr Pavard said vandals hurled the bricks from a footpath next to the school.

He said: "We have had regular problems with windows being broken. We cannot close the footpath because it is a right of way and it would get contentious.

"There's a problem in Durrington, with similar sorts of damage being caused on a regular basis. It's extremely disappointing.

"All the energy and resources, including money of course, which ought to be spent on better facilities for pupils is being spent on replacing things."

PC Lee Cook said police would have talks with Worthing Borough Council today to try to get the wall repaired.

He said: "We want to get the area cleaned up to make Durrington a safer and cleaner place to live."
