Two large steel gates at the entrances to the protected Majjistral Park were destroyed last weekend in an act condemned as “cowardly” by the Resources Ministry and the Mellieħa local council.
The vandal act was discovered on Sunday. The council, which forms part of the board that manages the park, urged anyone with any information to go to the police.
Vandals removed chains and the gates to both entrances and broke a number of information boards.
The council pointed out that the park, which was of great environmental value, was there to be enjoyed by everyone.
The ministry said it would continue working to creating public spaces for families.
