Gordon Wilson has been missing from his Leaden Roding home since Sunday, when he was last seen by neighbours at about 11am.

He was meat to have Sunday lunch with his daughter, but when she arrived Mr Wilson was not home.

Mr Wilson, who has vascular dementia, is thought to have left home on foot with a little cash and some medication.

Officers believe he boarded the Arriva 352 bus towards Great Leighs from Chelmsford Bus Station at just before 1pm on Sunday.

Mr Wilson, who is 5ft 11in-tall, enjoys long walks and has a bus pass that he may be using to travel. His health means he can become confused and have difficulty speaking.

Officers are also looking into whether Mr Wilson has travelled to Glasgow, where he lived for more than 70 years and served as headteacher at Shawlands Academy.

Mr Wilson is described as being of medium build with grey thinning hair. He wears glasses and was last seen wearing a sports jacket which is either checked or navy. He usually wears a shirt, tie and jumper.

Acting Chief Supt Ewen Wilson said: “It is worrying when anyone goes missing for this length of time but Mr Wilson’s age and health concerns make his disappearance even more concerning.

“My officers and I are continuing to make extensive enquiries to find Mr Wilson but I’m appealing for help from the public. We’re running appeals across our Facebook and Twitter channels so please share and re-tweet these and help us find this elderly gentleman.”

Anyone who thinks they may have seen Mr Wilson is asked to call Essex Police urgently on 101.
