The classroom is used to give free environmental education programmes for children of all ages and nature activities during summer for care home residents and older people with dementia.
Creggan Countrypark say: “We were devastated to find our wee outdoor classroom had been vandalised at the weekend.
“Volunteers, school children and funders worked hard to help us get this area transformed for community use.
“We use the space for our free environmental education programme for children of all ages and nature activities during summer for care home residents and older people with dementia.
“To those of you responsible we don’t know your reason or motivation for this despicable act of destruction but it won’t stop our services.
“The public path from Creggan to Glenowen is also a disgrace, we have reports of dogs having to be taken to vets for stitches due to injuries sustained from broken glass.
“We have reports of large groups of young people gathering at weekends.
“We appeal to those parents who have been seen leaving their son/daughter at the cropie to please consider their whereabouts and actions.
“We will be working with council and Triax – Neighbourhood Management Team to find a solution to the escalating antisocial behaviour on this pathway.”
He said: “It’s very sad once again to see a community facility being targeted by vandals.
“A few weeks ago we had the attack on the OLT building on Central Drive and now this.
“These vandals are hurting their own areas and hurting the organisations who are working night and day to provide facilities right in the heart of the community.
“I would urge anyone with information on those responsible to bring it forward straight away to prevent further attacks.”
Cllr Campbell added that he will reporting other weekend vandalism to the council.
“On the pathway between Westway and Glenowen another weekend of drinking and vandalism.
“I will be raising this at the community safety meeting on Tuesday and will speak with council about this.”
