There have been more cases of vandalism in the St Martins area of Guernsey. Police said property lights and traffic mirrors were deliberately damaged in Sausmarez Road in the early hours of Saturday.
The latest incidents follow a spate of suspected arson attacks and vandalism earlier in the week, including a fire at a derelict house.
Guernsey Police are investigating whether the same people are responsible for the attacks.
Andrew Major, the island's fire safety manager, has warned that someone could be seriously hurt if the situation is not brought under control.
