"His clothing is fairly distinctive and would appeal to anyone who may have seen him to get in touch."

David is known to walk around Norwich city centre, Magdalen Street, Anglia Square, Silver Road and Chapelfield Gardens.

Inspector Terri Cooper-Barnes said: "We are increasingly concerned for David and are continuing searches as we try to locate him.

"We have been working closely with his family to keep them up to date with any developments. If anyone has any information or a sighting of David, please get in touch."

Anyone with information or who knows of his whereabouts can contact Norfolk Constabulary on 101 quoting incident number 180 of January 1.
