A search operation is underway on Lough Mask, Co Mayo for a five-year-old boy who is believed to have fallen out of a dinghy.
Gardaí and the Coast Guard began the search on Monday after the alarm was raised at 6.30pm, when the inflatable boat was spotted in the water.
The missing child is reported to be from the local area and believed to have fallen from a dinghy which may drifted from the shoreline.
The Coast Guard helicopter, based in Shannon, Co Clare, conducted an aerial survey of the lake on Monday evening, while search teams worked to locate the boy.
