An investigation into a suspected arson attack on a derelict building in Donegal town on Halloween Night is continuing.
The incident occurred at Milltown, on Tuesday October 31st at around 8.45pm.
Gardaí were alerted to a fire at a derelict factory in the area.
The fire service attended the scene and extinguished the fire, but there was extensive damage caused to the interior of the building in the blaze.
It is believed that the fire may have started between 8pm and 8.45pm and that it may have been started maliciously.
Gardai are appealing to anybody who was in that area between those times and who had a dash cam to make the footage available to Gardai.
Anybody who may have any relevant information should contact Gardaí in Ballyshannon.
