A multiagency operation responded to what turned out to be a false alarm off Coney Island yesterday.
The alarm was raised by a member of the public, who believed to have seen a swimmer in difficulty.
Sligo Bay RNLI volunteers responded to what has been described as a false alarm with good intent at around 11.15am yesterday to a swimmer thought to be in difficulty off Coney Island.
The volunteer crew assembled and the lifeboat was launched at 11.25am and proceeded to the last sighting of the swimmer.
A comprehensive search of the area and then an extensive search was carried out following the incoming tide.
Other volunteer lifeboat crew made their way to both Coney Island and Oyster Island to carry out a shore search.
The area around Deadman's Point was also searched and other swimmers were asked if knew of anyone who had gone swimming that had not returned.
No one was reported missing.
The lifeboat was also joined on the search by Rescue 118 helicopter for a period of time.
After a number of hours searching, the lifeboat crew were stood down by the Coast Guard in what was believed to have been a false alarm call out with good intent.
Speaking following the call out, Aisling Gillen, Sligo Bay RNLI Lifeboat Press Officer said: 'We would like to thank the person who made the call as we would always prefer to launch and search and find that all is well and be stood down than not launch at all.'
