Vandals have damaged the skateboard park in Noble's Park, Douglas.
Between 4pm on Tuesday and 8am yesterday, somebody dug holes in the grass banks and destroyed a park bench which had only recently been put inside a shelter.
Officers say the damage may have been caused by people trying to make jumps for bicycles, and are asking anybody who saw what happened to come forward.
