A search has been launched for a missing hillwalker who may have become “disorientated” during a trek on the Isle of Rum.
Keen hiker Mary Molloy, 68, was last seen walking in the area between Trollabhal and Bealach an Fhuarain at around 2.30pm on Saturday.
She later got in touch with her family at around 6.30pm, but Police Scotland said it is unknown where she was at the time on the Inner Hebridean island.
The force believe Ms Molloy was attempting to make her way back to the Dibidil area and “may have become disorientated”.
Officers are becoming “increasingly concerned” for her welfare.
Inspector Graham Brown said: “Mary is a keen hillwalker but from what we’ve been told she may have become disorientated and failed to follow her planned route.
“We have specialist resources, including mountain rescue teams, helicopter and search dogs, in the area but we also need the public’s help with information.”
Ms Molloy is around 5ft 8in tall, of average build and with long grey hair.
When last seen she was wearing a turquoise waterproof jacket, red trousers, brown walking boots, a blue hat and red gloves. She was also carrying a grey rucksack.

Inspector Brown added: “I’d appeal to anyone who was on Rum on Saturday and thinks they may have seen someone matching her description to come forward.
“Also, anyone who may have known Mary’s intended route or areas she was keen to visit is urged to get in contact with us.”
