Fears are growing for a British tourist who has been missing in Thailand for more than four weeks.
Daniel Davies, 26, from Llanelli, Wales, had been staying at the Hangover Hostel in Bangkok before he was last seen on the island of Koh Phi Phi.
His desperate family say they have not heard anything from Daniel since March 13, which is 'highly out of character'.
They have filed a missing person's report with Dyfed-Powys Police, but officers in Southeast Asia have yet to locate him.
Daniel's aunt Nicola Doran said: 'My nephew Daniel Davies has gone missing in Bangkok, Thailand. He's been reported and is now a missing person.
'No one has had any contact in weeks.'
Friend Lucia Froom added: 'Daniel's phone is switched off and no one has heard from him in weeks, which isn't like him at all.
'If anyone knows anyone in Thailand or is planning a trip there soon, can people please keep an eye out for him.'
Daniel's disappearance is of particular concern amid a spate of deaths among Western tourists in the popular holiday destination.

Police in the UK said that Daniel is described as being around 6ft3 tall, of slim build, with blonde hair and a beard.
He also has a distinctive tattoo sleeve on one arm.
Missing persons charity Echoes of the Lost has also joined the appeal alongside SARS Cymru.
They said: 'Daniel, if you happen to see this post, please get in contact with your family. They are worried.
'If you wish to message us to pass information along, please feel free to do so.'
The British Foreign Office is reportedly aware of the case.
Thousands of British holidaymakers flock to Thailand and itsparadisiacal tropical islands each year in search of a picturesque, yet affordable, getaway full of rich culture, diverse cuisine and stunning views.
But the holiday hotspot, which relies heavily on itsdedicated tourist economy, has seendozens of Western tourists suffer unusual fatalities over the past decade - including at least two Brits this year alone.
Local authorities have explained the deaths as unfortunate accidents or suicides, though many cases appear suspicious to family members, or are left insufficiently investigated.
British tourist Nick Weir was tragically killed in a fight near a karaoke bar in Bangkok just last month after an apparent misunderstanding with staff, the bouncers have suggested.
The privately educated Briton - who managed a company in Salisbury and went to The International School of Brussels - was turned away from the 91karaoke bar in the early hours of Monday, March 24, before being pursued by two members of security on a motorcycle.
The bike stopped abruptly in front of Mr Weir before one of the bouncers, named locally as Mr Phurinat, 32, asked him: 'Is there anything I can help you with?'
Mr Weir at that point 'acted displeased', local media reports, and jumped on the motorcycle, as seen in CCTV footage near the club. The other bouncer, named only asMr Boonchu, then pushed Mr Weir away, igniting a confrontation.
Trying to clarify the situation, Mr Boonchu then held out his phone 'to translate', Matichon reports.
Mr Weir then reportedly tried to grab the phone but missed, before running into the road and trying to get on the motorcycle.
The three were seen fighting after one of the bouncers pulled Mr Weir off the motorcycle. The privately-educated tourist 'became still' after the held him in a restraining position on the ground, Matichon reports.
They called for help after Mr Weir was knocked unconscious, police said, but paramedics were unable to save him with CPR.
Nick Weir, 28, was travelling in Thailand when he stopped at the bar in Bangkok last month. He died in suspicious circumstances after being turned away from the bar

It was not clear what caused Mr Weir to act erratically when trying to get into the bar, or when trying to get on the motorcycle.
Lieutenant Colonel Apichai Hwanjit, Deputy Superintendent of the Bang Po station, said that Mr Weir had been turned away from the bar by staff.
But police said CCTV showed he did not appear to be drunk when he arrived at the bar because he was 'running in a straight line'.
However, they did say he was 'shouting and causing a commotion'.
'Currently, we are waiting for the forensic results to determine whether the deceased was intoxicated or under the influence of any substances.
'It is crucial for the case to ensure clarity. We are waiting for the blood test results to check for drugs or alcohol.
'From the CCTV footage, he did not appear to be in a typical state of drunkenness.
'He was running, shouting and causing a commotion, but he wasn't completely out of control. He ran in a straight line, not stumbling like someone who is drunk.
Mr Weir had already ran nearly a kilometre, police said, before reaching the karaoke bar.He was then seen running away from the bar before being stopped by staff.

Apichai acknowledged claims circulating in Thai media, that the men had tried to restrain him as they 'wrestled', causing Mr Weir to fall.
According to local media, Mr Phurinat 'climbed up and sat on' Mr Weir 'from the waist down, leaning forward' after he fell.
'Mr Boonchu locked his arms and pressed his head down on his torso, causing the torso to lie sideways until the foreigner became still'.
'We are unsure if there was any pressure applied during the fall that caused the death, so we are waiting for the forensic results,' Apichai said.
'The security guard nearby' called the police when tensions cooled.
Mr Phurinat and Mr Boonchu stayed at the scene and did not flee, police said.
One of Nick's friends, who was not named, said the behaviour was unusual.
They told ViralPress: 'I didn't know. That was not in [his] character at all.
'He was so polite, the nicest guy. I can't believe it. I can't process this. I knew he was in Thailand. I messaged him yesterday but haven't heard back from him.'
Mr Weir was identified as a privately-educated manager of a company in Salisbury, who went to the International School of Brussels before studying at Leeds University.
Local police said that the British Embassy had been informed of his death.
An FCDO spokesman told MailOnline: 'We are providing support to the family of a British man who died in Bangkok and are in contact with the local authorities.'
Mr Weir's death came just weeks after a 21-year-old holidaymaker was found dead on the popular Koh Tao island, which has earned the grim moniker 'Death Island' due to a concerning number of strange deaths in recent years.
Robby Kinlan, from Quilty in Co. Clare, was found dead in his resort bedroom on Koh Tao on January 9 this year. His family said that he was found with his phone in his hand and his earphones still in, lying on his bed.
Mr Kinlan was unresponsive when his friend knocked on the door at around 11am.
The door was locked and staff had to climb in, finding Robby tragically already dead.
Robby was found dead last Thursday on Koh Tao, which some refer to as 'death island' due to the number of unexplained or suspicious tourist deaths there
Officers said Robby Kinlan was staying at a resort fewer than two miles from the Sairee Beach where Hannah Witheridge and David Miller were bludgeoned to death in September 2014 - the incident which gave rise to the grim moniker 'Death Island'
'The room had not been broken into or searched, and there were no signs of any assault. He died alone in the room,' Lt Colonel Theeraphat Sanjai said.
'His friend confirmed that he didn't know if he had any pre-existing medical conditions,' he added, noting there were no alcoholic drinks in the room when police entered.
They said thatsaid that initial postmortem results found he had died as a result of acute pulmonary cardiac failure.
Mr Kinlan had just completed an advanced diving course on the island and was 'living his dream', friends said.
