Police were called to the Braichlie Road area of the Aberdeenshire village at around 11am on Monday after what they described as an “unexploded device” was found in a property.
The Explosive Ordnance Disposal (EOD) squad was also sent to the incident, which led to the evacuation of the four flats in the building.
The object turned out to be a deactivated Second World War device that posed no threat to public safety, officers said.
Inspector Megan Heathershaw, of Police Scotland, said: “Following a review, we can confirm that the item was a deactivated device from WW2 which has no explosive capability. It has been safely removed from the site. Once again I would stress that there was no threat to the public at any stage.
“Thank-you also to those members of the public who were affected while inquiries were carried out this afternoon. Your patience has been much appreciated.”
