Police are investigating a suspicious fire which saw a transit van engulfed in flames during a late night incident in the East Neuk.
Emergency services raced to the scene on Motray Crescent in Guardbridge at around 11.45pm on Monday.
A Ford transit van was discovered well-alight and fire crews used two jet hose reels and breathing apparatus extinguish the blaze.
A joint probe by Police Scotland and the Scottish Fire and Rescue service was subsequently launched.
Investigators have now confirmed they are following a positive line of enquiry in tracing the person responsible.
No one was injured during the late night incident but several residents were woken up by the unfolding drama.
Loud cracks and bangs could be heard while fire raged and smoke could be seen at the roundabout close to the Eden Mill brewery on Main Road – which is located in the site of the old Guardbridge paper mill.
