Parish representatives have called graffiti on a St Martin’s bus stop “sheer vandalism”.
A spokesperson for St Martin’s Constables said they were “dismayed” that the Old Mill bus stop had been spray painted, adding that many parishioners had “expressed their disgust”.
“We are reporting the matter to Guernsey Police and have appealed for any relevant CCTV footage that might be available,” they added.
The Constables are putting up a £500 reward for information directly leading to a successful prosecution.
