Police say they are growing increasingly concerned about a man from Wellingborough who went missing earlier this week.
Keith Errol Campbell, 59, of Midland Road, has not returned home since going out on Monday morning (June 11).
He was last seen in The Drapery, Northampton, at 7pm on Monday and has not been seen since.
Officers are concerned about Mr Campbell as he requires daily medication and it is believed he does not have any with him.
A Northamptonshire Police spokesman said: “It is believed Mr Campbell does not know anyone in Northampton and so officers are appealing for the public’s help in finding him to make sure he is safe and well.
“Mr Campbell is black, of stocky build, with short, greying hair and was wearing blue jeans and trainers when he went missing.
“Officers would like to speak to anyone who may have seen Mr Campbell since Monday, or may know of his whereabouts.”
Anyone with information can contact police on 101.
