A Pokémon hunter was taken to hospital after falling in Chesterfield woodland.
The woman, in her mid 20s, was in Linacre Woods when she fell, suffering injuries to her ankle, back, neck and elbow.
Members of Edale and Buxton mountain rescue teams were called out to help East Midlands Ambulance Service treat and move the patient.
She was suffering from hypothermia when she was located.
Ed Proudfoot, of Edale Mountain Rescue Team, said: "As an aside from the incident, we’d like to remind and encourage people enjoying the
outdoors to be mindful of the terrain and weather conditions they might encounter, especially this time of year.
"Proper footwear, waterproofs clothing and equipment can make the outdoor experience much more enjoyable, not to mention safer."
