A spokesperson from Police Scotland said the incident is being treated as “wilful fireraising”.
At least three fire engines, two police vehicles and several unmarked emergency service cars attended the incident.
A spokesperson from the Scottish Fire and Rescue Service said the fire was extinguished by 20:23 and the firefighters left an hour later after making the area safe.
