Missing Arthur Jones: Tourists who signed visitor book sought
Police from north Wales helping in the search for a missing Denbigh pensioner in Crete want to track down two Welsh tourists who visited the Greek island.
Arthur Jones, 73, from Denbighshire, has not been seen since 19 June, two days after he arrived in Crete.
The officers found Mr Jones's name in a visitors' book from the day before he disappeared, written just before two Welsh tourists signed it.
They hope Mr Jones might have spoken to them of his plans for a walking tour.
The guest book was at a World War Two cemetery in Souda Bay, close to the city of Chania where he was staying.
Any other tourists who signed the book are also asked to come forward.
North Wales Police are also asking any holidaymakers who visited the cemetery on 18 June to contact police.
Superintendent Steve Williams said: "The visitor's book shows that there were a number of British people there on the same day.
"Is your name on this visitors list or do you know anyone who has signed their name in the book? Our hope is that someone remembers seeing or even speaking to him.
"I would also ask that if anyone took photographs there to check whether Arthur is in the background as it may identify the clothing Arthur was wearing."
Earlier on Monday, local MP Chris Ruane said relatives had been told of a possible sighting in the Souda Bay area on 25 June, a day after he was due home.
They were going to the area on Monday to hand out missing person leaflets.

It is fantastic news for the family that there is a positive sighting of Mr Jones, but it is unconfirmed.
The problem overall is they have no exact location to pinpoint Mr Jones to.
The family have been very critical of the efforts put into the search (by local police) but it is very difficult to know how far they have gone and how far the family want them to go.
Officers from North Wales Police were meeting with officers from the Commonwealth Office last night and this morning they will meet with local police.
Every possible effort as far as possible from outside is being offered.
Equipment which he would have used on walks was found in his room in Chania after he disappeared, despite the fact he had sent his family a postcard saying he had planned a walking trip.
Mr Ruane said: "[There was] a reported sighting of Arthur in the Souda Bay area of Crete on 25 June, so that's a day after he was due to come back.
"The family are heading down there today to deliver leaflets in the area to jog people's memories, the people that live in Crete.
"But they have also asked me to release this because they want people who were are out in Crete - Arthur went out on the 17 June so anybody that was in the Souda Bay area or Chania between 17 June and today, if they do think they have seen Arthur then check it out on the BBC website and have a look at his picture, see if that jogs their memory and come forward with that information."
A mountain search and rescue expert from north Wales and two North Wales Police officers are flying to Crete to join the search.
