A 50-year-old man has died after collapsing in Yetlington, Northumberland.
The incident happened on Tuesday, October 6, and the victim was part of a shooting group.
The Northumberland National Park Mountain Rescue Team and North of Tyne Mountain Rescue Team were requested by the North East Ambulance Service to attend the scene.
The Great North Air Ambulance was unable to fly due to the prevailing weather conditions.
A spokesman for the Northumberland National Park Mountain Rescue Team said that hill fog and low cloud made it very difficult for any air asset to fly.
Team members, including a team doctor, were mobilised quickly, but despite the best efforts of all on scene, the man died.
The incident involved 14 team members for two hours. It is the third incident that the volunteers have responded to in less than two weeks, including a dramatic rescue of a hiker on Saturday, and the 44th incident in 2015, making it one of the busiest years in the teams’ history.
