Police from North Wales who are appealing for help in the search of missing Denbigh man Arthur Jones, say they're looking for any tourists who might have been on holiday in Crete around the time he disappeared.
In particular they're asking those who visited the Souda Bay Cemetary on June 18th to come forward.
A visitor's book shows that the missing man, who's 73, visited the World War 2 Cemetery on this date.
The book shows a number of other British and Welsh visitors, who may have seen Mr Jones.
Superintendent Steve Williams said:
"We know that Arthur has attended there on June 18th, probably around the early morning time. 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 he was wearing."
Arthur Jones has failed to make contact with his family and friends since June 18th.
