A joint investigation by Police Scotland and the Scottish Fire and Rescue Service has revealed that the Northbay Pelagic factory fire was not suspicious.
Investigations into the cause of the devastating blaze have been taking place since the incident on Saturday, January 17.
Speaking to the Buchanie last week, a spokesperson for Police Scotland confirmed that there was nothing to suggest the fire was started deliberately.
A spokesperson for the Scottish Fire and Rescue Service also confirmed the result but refused to comment.
The Peterhead company lost its main office block as well as its packing and processing lines in the blaze, but as reported in the Buchanie last week, Northbay Pelagic have lodged plans to Aberdeenshire Council for replacement buildings at the existing location.
Demolition work is currently ongoing at the Kirk Square site and is expected to continue for several weeks.
It is hoped that construction can begin on the new buildings once the site is cleared.
