Bomb disposal experts were called to Shetland after an item of suspected ordnance was found.
A group of personnel from the Clyde-based Northern Diving Group investigated the item that was found in the out-buildings of a local property.
They discovered that it was a World War Two hand grenade.
The Royal Navy confirmed they had attended the incident on Monday and made the grenade safe by carrying out a controlled explosion.
A spokeswoman said: “We can confirm that Royal Navy bomb disposal experts from the Clyde-based Northern Diving Group travelled to Shetland yesterday to investigate an item of suspected ordnance found in the out-buildings of a local property.”
