Volunteer rescuers were again out on the Cairngorms mountains in the search for a walker missing for more than seven weeks.

Members of Braemar Mountain Rescue Team extended their search to the high corries of Cairn Toul, Ben Macdui and Garbh Choire on Sunday in the continuing hunt for Jim Robertson.

They were aided by the Inverness Coastguard rescue helicopter which airlifted team members to the search site.

A team spokesperson said there was still plenty of snow on the hills and added: “The long walk out was not required after R951 turned up and offered us a lift out, needless to say it was accepted.”

The 61-year-old experienced hillwalker has not been seen since 2 March, when he is believed to have stayed at the Bob Scott Bothy, close to Derry Lodge.

Extensive searches by the Braemar and Aberdeen teams, along with other volunteer mountain rescuers, has failed to find any trace of the Glasgow man.

Mr Robertson’s daughter Lynn set up a justgiving page to raise funds for Braemar MRT in her father’s memory, which to date has raised more than £11,500.

Anyone with information that may help in the search for the walker is asked to call police on 101.
