Police are appealing for help in tracing a man who has been missing from Wyboston since Monday (4 January).
Stephen Perloff, 46, was last seen at the Milton Park Hospital and officers are growing increasingly concerned for him.
He has links with both Cambridgeshire and Essex, in particular with Southend.
Detective Inspector Andy Southam, investigating, said: “We are worried for Stephen because of his unplanned disappearance and he also may require treatment for his health issues.
“I’d urge Stephen himself, or anyone who believes they may have seen him, to contact us immediately so that we can ensure he is safe and well.”
Stephen is described as 5’10”, slim, clean shaven, with black hair, and speaks with a South African accent.
He was last seen wearing a black coat, black trousers and black trainers.
Anyone with information is asked to contact Bedfordshire Police on 101 quoting reference number 368 of 4 January.
