STAFF have slammed vandals who again wreaked havoc at their nursery.

Children at Rowley Lane Pre-school in Lepton have in the past had their playground covered in smashed bottles and even drug paraphernalia.

On Sunday the manager came to the site to discover window boxes had been ripped from the pupils’ Wendy house and wooden planks also removed and smashed in through the door.

In the past yobs have also been filmed on CCTV targeting their vegetable garden.

Police were given footage of the incident and warned that as the site was private property those responsible would be treated as trespassers.

School chairman Vanessa Mallinson said: “Unfortunately this seems to be an ongoing thing.

“On Sunday the manager was taking in some compost in for a planting session with the children. When she’s gone into the site with her husband she’s realised what’s happened.

“All the window boxes have been stood on to get on the roof, so they’ve been ripped off and the there’s other damage to it the Wendy house itself.

“It feels like one thing after another so it’s pretty tragic.

“They’ve split pieces of the wood and the planks have been pulled off and put through the door – it’s just mindless vandalism.

“As we are a charity we require a lot of fundraising and this makes that even harder.

“We have alerted the police and they are looking into it.”

The school places a particular emphasis on nature and the environment.

In April last year a spate of attacks led Headteacher Lynne Rutter to accuse the culprits of “spoiling the school premises”, particularly flower beds.

They were also concerned by the level of drug abuse taking place during the wrecking sprees, with empty cannabis bags and cigarette papers littering the scene.

Letters were issued to parents to ask inform them about the situation and ask for their help in catching those responsible.

Assemblies were also held to emphasis the message of caring for the environment and other people.

A spokesman for West Yorkshire Police confirmed that the matter was being investigated.

They asked for anyone with information to ring 0845 6060606 or Crimestoppers in confidence on 0800 555111.
