A lifeboat launched in the north-east after an “unidentified object” was spotted in the water.
The Montrose Inshore Lifeboat was called out by the Coastguard at just after 4.30pm today after an unexplained object was spotted in Montrose Basin.
The crew investigated the object and stood down shortly after.
It is understood the object was a type of distance marker.
A Coastguard spokesman said: “Montrose Lifeboat was launched at 4.35pm after being notified of an unidentified object at Montrose Basin.
“The object found was non search-and-rescue related and so the lifeboat was stood down.”
The crew returned to base at around 5.35pm.
