POLICE say they have received calls reporting "potential sightings" of missing York man Joseph Cafferkey, who was last heard from two weeks ago today.

The last confirmed location for the 72-year-old, of Dijon Avenue, Acomb, is when he used his home phone to call a neighbour, on the afternoon of September 30.

Despite extensive police searches, Joseph has not been found.

A spokesperson for North Yorkshire Police said his disappearance is "out of character," and officers are "extremely concerned for his welfare."

Following enquiries, police have developed a timeline of the days prior to Joseph going missing.
