Lincolnshire Police are continuing to search for missing man Robert Taylor, 51, who was last seen setting off from his home in Sleaford at 11.30am on Monday February 1.
The force originally issued an appeal on February 4 for any information about him or any sightings of him to be reported.
A police spokesman said: “Robert’s family are very concerned because he has not made any contact since he left and for him to go missing is very out of character.
“Robert did not have his wallet or medication with him, which is adding to his family’s worries. It is thought that he was wearing a green polo shirt with grey/brown cargo trousers but it is not known which coat he may have taken.”
Anyone who has seen him or knows of his whereabouts should call 101.
