The fire started on Friday evening between 6 pm and 7 pm when the front door was set alight and police are keen to speak to a man who was seen a few times during the day hanging around in a field opposite the property at Westhill and who was carrying what looked like a skull on a stick.
The man is described as being 5’9, of medium build with dark coloured collar length hair and he was wearing dark coloured clothing.
No one was hurt in the fire which was put out by firefighters but it did cause minor damage to the property.
Anyone with information is asked to call the Police on 612612 or Crimestoppers anonymously on 0800 555111.
