The Cambridgeshire Major Crime Unit has since taken the lead in the search.
DI Rich Stott said: "We are extremely concerned about David's whereabouts and what may have happened to him, given the length of time he has been missing and the unexpected nature of his disappearance.
"Any information, no matter how small, could prove crucial to finding him.
"As time goes on we have to consider all possibilities about what has happened to David and one of those lines of enquiry is that he may have come to harm."
Anyone with information is asked to contact the Major Crime Unit police on 101, via the Major Incident Public Portal or Crimestoppers on 0800 555 111.
