A search is under way in Killarney Co Kerry for a 42-year-old man who has been missing since yesterday.
Matt Hodd, an ecologist and a local poet, was last seen in the Whitebridge/Millroad area of the Flesk River.
The Shannon-based Coast Guard helicopter has been involved in the search which is covering woodlands as well as waterways.
