Gardai are asking motorists to view dashcam footage following a suspected arson attack in broad daylight in Falcarragh.
The blaze happened yesterday afternoon at around 3pm in the Derryreel area.
Extensive damage was caused to an unoccupied bungalow but nobody was hurt in the incident.
Gardai say early indications are that the fire was started maliciously and have appealed for anybody who was in the area at the time or may have dashcam footage to come forward.
It is the second suspected arson attack on a home in the county in recent days.
However, Gardai do not think the attacks are connected.
Another fire gutted a family home in Kilmacrennan earlier this week.
A young family were due to move into their dream home before Christmas before it was torched on Sunday last.
