Vandals carried a sofa to a playground and torched it underneath a set of swings.
The settee was burned on Monday and caused damage estimated at £2,500 to the swings and safety surface at Wombwell Park.
“The park is well used and over recent years has seen a number of improvements thanks to the work of parks officers, friends group, and other members of the community.
"We can’t understand why someone would try to undo all the hard work by recklessly damaging the place. There are unprecedented and well-publicised pressures on council budgets, and it simply isn’t possible to continually replace damaged and stolen equipment.”
Brian Whittaker of the Friends of Wombwell Park, said: “We have a lot of plans for the park and will continue to volunteer and fund raise to make sure it continues to be a great place for families to visit. Sadly, mindless acts like this do make you start to ask if it’s all worth the effort.”
Anyone with information should contact police by calling 101.
