The leader of the Glencoe mountain rescue team has shed more light on the search which ultimately resulted in two men and two women being found dead in the Scottish Highlands.
John Grieve said:
The first call to police was from two other people who had been on the mountain, they found someone lying next to where they were climbing.
So, the assumption was that it was just one casualty, but it became clear that there were others missing when they heard from the man who is safe.
He added that they were located using a technique called "probing" - where a metal stick is pushed into the snow - which would indicate they were buried in more than a metre of snow.
