A search operation is under way in Co Mayo for a fisherman who has been missing since yesterday. 

The fisherman, who is in his late 70s, went out on his boat on Lough Mask in the Cushlough area of Ballinrobe. 

The alarm was raised last night and the Coastguard, Community Rescue Boats Ireland (CRBI) and gardaí are involved in the search. 

The man's boat has since been recovered.
