Gardai are investigating an overnight break in at the Super Valu shopping centre in Dungloe.
A van belonging to the company was also stolen but it has been located on the outskirts of the town.
Access was gained through the roof of the premises while CCTV was also removed.
Gardai say that the break in bears striking similarities to other recent break ins in Killygordon, Letterkenny, and Laghey.
The scene is currently preserved for a technical examination and Gardai are also maintaining a presence where the van was recovered.
It is not know yet what was stolen from the premises.
Gardai are appealing to anyone with information to come forward.
