The Northern Echo: The last known image of Jeffrey before his disappearance.

He is described as white, 5ft 10ins tall and he is mostly bald. He walks with a distinctive "laboured" walk, caused by an existing back problem.

Police are becoming increasingly concerned for Jeffrey’s welfare as he has now been missing for a week. It is believed that he may have headed towards nearby green belt areas around the River Tees, off Bowesfield Crescent and Thornaby Road.

A spokesperson for Cleveland police said: "Officers are continuing to search for him and are asking anyone who may have sighted him, or who knows where he is to call 101 quoting reference 196739."
