The family of a 73-year-old man who went missing on Crete two days after arriving for a walking holiday have appealed for information.
Son Jeff appealed for help in finding his father on Good Morning Britain, and said he hopes someone who had returned from a holiday in Crete would recognise pictures of his dad.
Arthur is a competent and experienced hill walker who had been to Crete before, but went missing two days into his trip.
The father of four arrived on the island of Crete on June 17 and planned lots of walking trips.
A social media campaign under the hashtag #FindArthur has helped garner support, but relatives are desperate for news about the former soldier.
He sent postcards to his family and visited a local World War Two cemetery, where he signed the visitors book on Wednesday June 19.
Arthur was last seen by a cleaner working at his hotel, the Pardalakis Apartments in Gerani, on the Thursday morning.
He has not been seen since and all his walking kit was found in his hotel room after relatives became worried about his whereabouts.
Although the hotel reported him missing, his family were only alerted when he failed to return home the following Tuesday.
Anyone with information should contact their local police force on 03003300101 quoting the North Wales Police reference number R103354.
