Cambridgeshire Police are growing increasingly concerned for the welfare of 66-year-old Peter Atkins.
Members of staff at Kneesworth Hospital, Bassingbourn, reported Peter missing at about 4.15pm yesterday (1 August).
He is considered vulnerable and officers are appealing for the public’s help in finding him.
He is described as a white man of a stocky build, with short grey hair wearing black trainers, blue jeans and a white or black t-shirt.
DI Dave Savill said: “Concerns were reported to us when Peter failed to return back to the hospital at 3.45pm yesterday.
“He was seen withdrawing cash at Royston Tesco at 2.10pm and is believed to have then travelled by bus into Royston town centre.”
We would urge members of the public to be vigilant and if they think they see him, not to approach him but to call 999.
Anyone with information should call police on 101, quoting incident 303 of 1 August.
