The Clapham-based Cave Rescue Organisation were called out to nearby caves after a visitor collapsed with chest pains.

The man, 65, was just over half-way along the show cave when he collapsed at 11.32am yesterday at  White Scar Cave, Ingleton.

After monitoring and treatment by paramedics from Yorkshire Ambulance Service and North West Air Ambulance, he was packaged by CRO members, then carried by stretcher to the road ambulance outside.

As CRO members stood down, the paramedics were checking him again, to determine which ambulance would take him to hospital.
