A WALKER died on a North Yorkshire summit despite the 'best efforts' of rescuers.

Cave Rescue Organisation (CRO) was alerted by Cumbria Police and North Yorkshire Police on Saturday (June 8) to reports of a man who was, according to the team, 'unconscious' and 'not breathing'.

"Once it was established this was a single incident and the location was close to the summit of Whernside which borders both counties the team was able to respond," said a spokesperson for Cave Rescue Organisation.

The team also made a request for Yorkshire Air Ambulance to attend through the police.

Two medical professionals who were walking on Whernside had already begun CPR and they also had a defibrillator with them.

"Sadly despite their best efforts and those of the helimed crew, the casualty could not be resuscitated," said CRO.

"The team then worked with the helimed crew to evacuate the casualty to the road head for transfer to the police and ambulance crew."

"The team’s thoughts are with the deceased’s family and friends."
