Mr Haughton (55) is five feet seven inches tall and has short grey hair. He is thought to be wearing a red fleece and blue jeans.
His disappearance is out of character and his family remain very concerned for his welfare.
Officers are appealing to Mr Haughton, or anyone who has seen him, to contact them on 101.
