Police divers are set to join the hunt for a man missing after a canoeing tragedy that claimed the lives of his two young sons and a five-year-old girl.
A fourth day of searching has found no sign of Ewen Beaton, 32, who is presumed drowned after a boat overturned in Loch Gairloch near Ullapool in the Scottish Highlands on Sunday afternoon.
His sons, Jamie, two, and five-year-old Ewen, died later that night after being rescued by helicopter from the water and airlifted to hospital.
A third child, Grace Mackay, from Muir of Ord, near Inverness, died in the Royal Hospital for Sick Children in Glasgow on Monday afternoon.
Her 35-year-old father, Garry, and eight-year-old sister, Callie, had managed to swim to the shore and raise the alarm.
Police officers and a Coastguard crew continued their shoreline hunt for Mr Beaton, from Beauly.
A member of the Coastguard and the RNLI also carried out searches by boat.
Northern Constabulary said members of the Grampian Police underwater search unit are expected to join the operation on Thursday.
The force has said it will continue searching for Mr Beaton for the "foreseeable future".
His family said in a statement that they were "utterly devastated" following the accident, while relatives of primary one pupil Grace have paid tribute to their "beautiful angel".
