An extensive search operation has resumed on the north western section of Lough Mask this morning after a five-year-old boy was reported missing yesterday.
Gardaí and the Coast Guard service are involved in the search for the boy.
The child is from the local area and is understood to have fallen from a dinghy which may have drifted from the shoreline at Treen, Tourmackeady.
The alarm was raised at 6.30pm yesterday evening when the small craft was spotted in the water.
Midwest News understands that the child is the youngest of five siblings and entered the water after he had been playing with his siblings on a dinghy.
The Corrib Mask Search and Rescue team is involved in the operation, with locals also offering assistance.
The Sligo and Shannon-based Coast Guard Helicopters conducted aerial surveys of the lake last night, with search teams also working to locate the boy, on water and from the shore.
The search continued into the night and resumed at 6am this morning.
Divers from the Grainne Uaile Sub Aqua Club Search and Recovery team also searched the water last night.
Search dives resumed at 7am.
