Several blue markings have been found spray painted over various parts of Pembroke Natura 2000, Nature Trust Malta confirmed.
Preliminary investigations indicate that the markings are not washable.
Last month, a Frenchman was taken to court for spray painting red arrows at Majjistral Park. It was found that French marathon organisers were responsible for such arrows, which were also found in Munxar, Gozo.
