Part of an Angus beach was sealed off on Saturday over a suspected bomb alert.
Police and Coastguard were called to a section of foreshore near Carnoustie after a member of the public discovered what they believed to be ordnance exposed by the low tide.
A cordon was put around the site.
Police Scotland confirmed the alarm centred around the possibility of the items being wartime material and the Explosive Ordnance Disposal (EOD) unit was informed.
They did not travel to Angus but it was confirmed the suspect items were rocks.
Emergency services left the area shortly after 4.30pm.
Kyle Constantine was walking his dog at Kinnaber, north of the Angus town last Saturday when the teenager came across the rock-covered mine.
It was destroyed in a controlled explosion by the EOD team.
