More than 1,600 concerned Epsom residents have joined a Facebook page dedicated to finding a man who has been missing for nearly two weeks.

James Middleton, known as Jim, was last seen at midday on Sunday, July 2, when he went out on his mobility scooter heading towards the Stew Ponds and Christ Church Road area.

He would usually go for a ride over Ashtead and Epsom Commons for two or three hours.

But the 70-year-old dementia and Parkinson’s sufferer has not yet returned home or been found, despite police helicopters being scrambled and officers and hundreds of volunteers scouring the area.

Jim is white, 5ft 6ins, of large build, with brown eyes and brown greying hair.

He was wearing a black or very dark grey, body warmer, a grey tee shirt, dark grey shorts, blue trainers and short white socks. When he left home he was wearing sunglasses.

Jim’s brother, David Middleton, recently made a heart-felt plea for help from the public from the group, Find James Middleton.

He said: “We are so grateful to everyone who is helping with this search, the whole community has been outstanding – I’ve never experienced people coming together like this before.

“Our thoughts are that somehow he has become separated from his mobility scooter, which may have been found and the finder thinking it was abandoned, has taken it.

“We have spoken with Surrey Police who are leading the search for Jim and they have assured us that a full amnesty will be given to anyone who has the scooter, that contacts them either directly or via Crimestoppers if they are not happy to speak to the police directly.

“We really need to know where the scooter was first found.”

Anyone with any information about Jim should contact Surrey Police on 01483 571212
