Mountain rescuers went to the aid of a walker who was suffering from chest pains.
The man was walking near the River Eden yesterday, at Armathwaite in Cumbria, when he got into difficulties.
Penrith Mountain Rescue Team was alerted at 3.35pm yesterday.
A spokesperson said: “Members of the team were able to insulate the casualty and stretcher him to a team Land Rover, which was then able to drive to the nearest road to the awaiting ambulance.
“The air ambulance was also in attendance. 15 members of the team were involved for two hours.”
The Penrith team has also been helping police in searching for a missing angler on the banks of the River Eden near Carlisle.
Nine members took part in a 3½-hour search today, following an 8½-hour hunt for the missing man by 10 of the team on Thursday.
