A lost party of cavers were brought to safety in an overnight rescue operation.
The alarm was raised that a group exploring the Ringing Rake Slough system near Matlock Bath had not returned to the surface just before 21:00 GMT on Tuesday.
Derbyshire Cave Rescue Organisation volunteers and Derbyshire Police were called to the scene. Teams went underground at 22:30 and were able to locate the group “after a good search”.
The lost cavers were warmed and then with some digging “in tight areas” were escorted back to the lower entrance near Matlock Mining Museum unharmed just before 05:00 on Wednesday.
