A rescue team went to the aid of a walker who suffered chest pains at South Pennines beauty spot.
Calder Valley Search and Rescue Team was called out to Brontë Falls, near Haworth on Saturday after a request from ambulance staff.
Team members were planning a search for a missing elderly man from Todmorden in West Yorkshire when they received the call for urgent help with the walker.
Tim Ingram of the rescue team said: “As there was an immediate risk to life, 18 CVSRT members responded to this incident.
“On arrival, CVSRT members with equipment were deployed to the patient’s location. Working with the [Yorkshire Ambulance Service] paramedics, team members treated the patient and reassured the family, who were close by.
“Once the patient was comfortable, he was placed on our stretcher and carried approximately 500m uphill to where the ambulance was waiting.
“While loading the patient into the ambulance, we received the good news that the missing Todmorden male had been found safe and well in the search zone, so team members stood down and headed home.”
Later in the evening, Calder Valley team volunteers were alerted to another missing pensioner from Halifax. At 1am, 13 members were deployed to help West Yorkshire Police with the search for 75-year-old Granville Muir, who went missing from his home in the King Cross area of the town.
Mr Ingram said: “After searching and clearing areas of interest, the team stood down at 4.15am. Police enquiries are ongoing.”
“If anyone has seen or knows the whereabouts of Granville Muir who went missing yesterday at 1pm, please call 101 and quote Log 1491.”
The callout capped a busy 24 hour period for the Mytholmroyd-based team, which had also attended an emergency services open day at Halifax police station.
