– Statement from the family of Graham Roskell
"Our dad, Graham Roskell, is missing. This is an urgent plea for your help to find him. He went missing from Harrogate District Hospital around 8 o'clock on the morning of Saturday 3rd November 2012, where he was receiving medical treatment for an infection which has spread to his brain, causing confusion, disorientation and anxiety.
“This is treatable, but only if he receives this medication immediately. Without it, his condition will deteriorate rapidly - particularly given the cold and wet weather.
“He is a loving husband, dad and grandad, who is the centre of our universe. We need him back now. We are urging people to check their outbuildings, garages, sheds, cars, anywhere he may have taken shelter.
"We also need help to hand out flyers and posters or just ask around and spread the word. Due to his condition he may have gone further a field than the Harrogate, or even Yorkshire area, and got himself lost."
"We want this to be a happy news story, where the communities pull together to find our Dad. The police are doing everything they can but we need the public’s help too."
Mr Roskell is described as white, 5ft 11in tall, with a medium build. He has greyish white straight hair. He was wearing glasses when he was last seen but his family say he does not need them all the time.
When he was reported missing Mr Roskell was wearing black leather lace up shoes, olive green trousers and a cream and green horizontally striped rugby style top.
He was also wearing a black wrist watch, and was carrying a navy blue fleece knee-length dressing gown that was rolled up.
Officers have been searching the Harrogate area, concentrating on open land and wooded areas around his home in Kirk Hammerton.

"This is a very worrying and difficult situation for Mr Roskell’s family.
"They are being very brave given the circumstances and are helping the search for him themselves.
"Specially trained officers have been searching Harrogate and the surrounding areas for Mr Roskell since he was reported missing and those searches are continuing.
"I would urge the public to help the effort to find Mr Roskell by reporting any sightings of him as soon as possible and checking any outbuildings where he may have taken shelter."
Mr Roskell’s family have also set up a Facebook page to help raise awareness of his disappearance and encourage people to help in the search for him.
