A vulnerable pensioner who was missing for five days was found asleep in a field - by his granddaughter.

Granville Muir, 75, went missing from his Halifax home on Saturday.

His desperate family launched an appeal, describing their worry for Granville, who has diabetes and memory loss.

But despair turned to joy when West Yorkshire Police announced last night that Granville had been found safe and well, but fragile.

And the story took a heartwarming turn when his granddaughter Drew announced on Instagram that it was she who found him asleep in a field off of Scarr Bottom Road, Halifax.

On the post on Wednesday night she said: “Found my grandad tonight with the help of a huge search party. Me and three of my amazing friends came across him when we decided to go completely off the beaten track for some strange reason!

“He was lying on the ground, peacefully asleep.

“He’d even taken his shoes and hat off. He’s just in hospital with his family around him now. How he’s survived for four nights and five days without food or drink is beyond me.

“I can’t even begin to thank everyone through all this. These five days have felt like a lifetime but with so many people offering their help and support it’s been much easier for me and mum to deal with.

“Remember to tell your family how much they mean to you as often as you can. SO MUCH LOVE XXXXX.”

West Yorkshire Police, mounted section, dog unit, helicopter, West Yorkshire Fire and Rescue Service, Calder Valley Search and Rescue Team volunteers and British Transport Police helped in the search for Granville.

Superintendent Owen West of Calderdale District Police, said:“We were growing very concerned for Granville so I am delighted to report a happy ending. On behalf of the Calderdale District and Adele Muir (Granville’s daughter) I would like to thank everyone who helped in the search. It truly was a team effort with everyone working together on behalf of a vulnerable missing man.

“The fact that we have been able to return Granville to his children and grandchildren is thanks to that effort and hard work, with people going above and beyond to help.

“I also want to pay tribute to the media who ran our appeals and everyone who shared our messages through social media channels - the response from people was nothing short of phenomenal and really helped when time was of critical importance. It just shows the power of social media in particular to help in police operations.”
