Police are warning folk to expect a loud bang when unexploded World War II bombs are detonated today.
Earlier this week, a walker in Glen Doll, Angus discovered what has been confirmed as unexpended old mortar shells.
A police statement said: “While posing no immediate danger to the public, they still need to be disposed of, so later today experts from the Army’s Explosive Ordinance Disposal squad will be carrying out a controlled explosion to dispose of them safely.
“Relevant exclusions will be in place and there will be no risk to the public, however it’s fair to say that there will be a rather loud bang at the time, which will probably be heard some distance away. We can assure you that this will be nothing to be concerned or worried about.
“Also, we would like to thank the person who found these items for bringing them to our attention.
“If anyone ever discovers anything which could possibly be a discarded or disused explosive, then we advise you not to touch it, but to mark and note the location as best possible, and notify the police.
“If anyone has any queries about exclusion areas and altered walking routes for today, please contact the Glen Doll visitor centre for details.”
