A derelict house in Raphoe was set alight in a suspected arson attack last weekend.

A number of fire engines were called to the scene and brought the incident under control.
No injuries were sustained as a result of the fire at the standalone property.
However, investigating Gardaí have confirmed that they believe the fire was started maliciously.
