Police have said the disappearance of Buxton man Tim Frohwein, a top police officer, is “totally out-of-character.”
Mr Frohwein, 48, Chief Inspector in Chesterfield with responsibility for Chesterfield and the Amber Valley, was last seen in Buxton at around 2pm on Sunday.
Assistant Chief Constable Dee Collins said: “This is totally out-of-character for Tim and I’m extremely concerned about him.
“We have carried out extensive searches, with the assistance of the local mountain rescue teams, who as they always do, have given us their full support.
“I would be very grateful if anyone who has seen Tim since he went missing contacted us. And I’d also like to appeal to Tim himself to get in touch. His family are very worried about him.”
Mr Frohwein was wearing a three quarter length dark coat, pale blue shirt and brown jeans. He may be carrying a walking pole.
He has short dark hair and wears glasses.
Police are becoming increasingly concerned for his well being because he is recovering from recent knee surgery.
Anyone who sees a man matching this description, or who has information as to his whereabouts, should call police on 101.
