A search is under way for a walker missing on Lochnagar.
Police Scotland said the 52-year-old male hiker was reported missing at 7.30pm last night after failing to return from a walk on the mountain near Braemar, Aberdeenshire.
Braemar Mountain Rescue said a rescue helicopter had been hampered by blizzards and cloud.
Team members carried out a search on foot overnight alongside Aberdeen Mountain Rescue.
They reconvened at 7am on Saturday to continue the search at first light.
