A Royal Navy bomb disposal team were called in tonight after a walker spotted a submarine smoke marker – complete with warnings how to disarm it – on a Western Isles beach.
The device, with instructional writing on it, was found at Hushinish on Harris at 1.42pm.
Coastguards from Tarbert cordoned off the area where it was discovered.
A spokesman for Stornoway Coastguard said an Explosive Ordnance Disposal unit from HM Naval Base Clyde at Faslane was on its way and due to make the device safe tomorrow. He appealed for the public to stay away from it.
The markers are routinely used in military exercises held around the islands.
