North Wales Fire Service and Rhyl Coastguard were called to Horton’s Nose in Rhyl on Sunday afternoon after fire began to spread along the sand dunes.
Fire broke out on Horton’s Nose just before 5pm with flames grown quickly. Point FM’s Craig K who was walking his dog along the public footpath at the time called the emergency services after seeing the fire break out in front of him.
Horton’s Nose became struck by fire back in 2010 after apparent arson, the area which is home to many species of plants and animals, including the common lizard, skylarks and burnet moths, and cormorants, sandwich terns and oystercatchers.
North Wales Police took a male into custody and the investigation is ongoing.
