Arthur Jones family give David Cameron letter over Crete help
Campaigners searching for a Denbigh pensioner who disappeared on the Greek island of Crete have delivered a letter to the prime minister calling for help.
Arthur Jones, 73, disappeared two days after arriving on holiday last month.
David Cameron previously said he would do "everything he can" and the letter from Mr Jones' family and friends says they are "still waiting".
A UK government spokesperson said they were already giving the family consular assistance.
Keen walker Mr Jones, who was staying in Chania, has not been seen since 19 June and did not board his plane home on 24 June.
Official searches have focused on the area between his hotel and a nearby war cemetery where he signed the visitor's book.
In the last week, six men from Denbigh, including firefighters and ex-soldiers, have flown out to Crete to the south of the island.
Now local supporters have started a campaign which has been circulating on social media saying "#CameronPromised", and is also printed on a large banner hanging in Denbigh town centre.
It follows Mr Cameron's offer to help earlier this month after the case was raised in the House of Commons by Mr Jones's MP, Chris Ruane.
Family friend Mari Calagui said; "We expect him to follow through with the promise he made a few weeks back at Prime Minister's Question Time in parliament - that he would promise any help possible to the consulate and the family."
She added: "They [the family] are hoping for a professional search team from the UK with search dogs and the paraphernalia that they have to go out there and enhance the search basically, with their expertise."
Some of the friends involved in the latest search for Mr Jones are continuing this week but Ms Calagui says that extra help is needed.
"Everybody's hoping that Arthur will be found alive and well and come home safely," she added.
"But paramount in all of this is that he is found."
A UK government spokesperson said: "We are providing consular assistance to the family of Mr Jones. UK police are assisting the Greek authorities with the investigation."
A Foreign Office spokesman said they were also providing assistance.
