Investigations are continuing into a spate of criminal damage incidents in the Oldtown area of Letterkenny.
At around 8:05pm on Thursday night last, a brick was thrown through the window of a house at James Larkin Court.
A few hours later, at 1.15am on Friday morning, a number of other windows at the same property were smashed by rocks.
Gardaí say they are particularly interested in any sightings or dash cam footage of a dark blue BMW with Northern Irish registration plates seen in the area at the time.
They are appealing to anyone with information to contact them in Letterkenny.
