Police hold grave concerns for an elderly man missing since Sunday in the Hunter Valley.
Bob Baihn was last seen late on Sunday afternoon, when he went to search for a missing pony on a property on Flaggs Road at Gungal.
His wife and a neighbour then started searching for the 72-year-old after he failed to return home.
Upper Hunter police searched the area yesterday. They were assisted by the dog squad, police air wing and SES volunteers.
The search resumed again this morning.
Mr Baihn has a medical condition that requires regular medication.
