Derbyshire police say they are becoming increasingly concerned for a Chesterfield man who has gone missing from hospital.
Roy Thompson, 60, was last seen at 9.20am on Thursday and his family has issued a desperate appeal for information.
He went missing from Chesterfield Royal Hospital and was described by his nephew, John Jackson, as a very confused man who needs help.
John said: “He has been a very clever and very healthy man all his life but in December last year his mental health deteriorated quite dramatically.”
He had been in Africa since April but was flown back to the UK for health reasons.
He has given his life to working with the United Nations and helping developing countries and has two daughters and a son in Africa and another daughter in Manchester.
John added: “He was last seen walking to Calow and it is very rural there and the state he is in is really worrying.
“I feel sick thinking he is missing – we need him home so he can get the help he needs.
“He’s not going to be violent if you meet him but he is going to be very confused and anxious so please be patient and kind with him.”
On Monday, October 12, Roy went so see his local GP who then said he needed to be admitted to hospital.
He was last seen wearing grey tracksuit bottoms, a green polo shirt and crocs.
He is 6ft 3in tall and of medium build with short grey hair. He speaks with a slight South African accent.
Anyone with any information should call police on 101, quoting reference number 301.
