Vandals have struck again at Happy Mount Park, Morecambe, this time causing £1,000 of damage.
Trampolines were ruined after five sets of canvas were vandalised overnight on Wednesday, September 4 into Thursday.
It follows incidents in July and August where the cafe door was attacked in an apparent break-in attempt and fence panels were damaged.
Morecambe police officer PC Jo Clement said: “There have been three mindless acts of vandalism over the summer months and we are appealing for people to come forward with information.
“Incidents like this do strike at the heart of the community as the facilities in the park are enjoyed by many people.
“We need to find the people responsible and bring them to justice.
“If anyone does know who is behind these incidents then I would urge them to call us on 101.”
