PC Nigel Brailsford is appealing for information about damage that was caused to a beach chalet on North Promenade, Mablethorpe, on the night of Friday August 30.
The door to the chalet was forced and then a fire was set inside. Fortunately, the fire did not take hold but considerable damage was still caused to the chalet during the incident.
A 20-year-old local man has been arrested on suspicion of arson and subsequently bailed while enquiries continue.
PC Brailsford is keen to hear from anyone who was in the area that night and witnessed the damage being caused.
Anyone with information should contact PC Braislford by dialling 101.
