Castletown commissioners are urging the public to report anything suspicious after a spate of arson attacks in the town.
The board says its cleaning staff have found evidence somebody has tried to start fires in public toilets around the town.
Earlier this week, the local authority closed one block near the town hall out of hours following an attempted arson attack.
Now, it's urging people to report anything unusual to the local policing team on 822222 or by emailing clerk@castletown.gov.im
