The thoughtless thugs damaged a new hut for the nursery garden at Craighead School, threw garden chairs on the school roof, set fire to bins and smashed eggs on the windows.
The £430 hut had only been erected before the summer break, paid for by the hard fundraising work of the local community.
Depute Headteacher Katie Thompson who discovered the damage when staff returned to school last week, said: “We are heartbroken.
“The children, staff, parents and community partners pulled together and worked to hard to make the garden a fabulous environment for the children.
“The hut was actually put up by a group of parents. It really was an example of true community spirit and for this to happen is very disheartening.
“It’s not just the monetary value, the garden is such a positive addition to the nursery. The children loved it and they are all very upset.
“We now have to look forward and focus on finding ways to get the nursery back to the way it was.”
The nursery at Craighead presently caters for up to 40 children in the morning and 30 youngsters in the afternoon.
A police spokesperson at Kirkintilloch said their enquiries were continuing into the vandalism at the school and appealed to anyone who could help to call them on 101.
