Tourists in Thailand may soon have to wear identification wristbands, the country's tourism minister has claimed, amid ongoing concerns over tourist safety.
It follows the murder of British tourists Hannah Witheridge and David Miller earlier this month.
Kobkarn Wattanavrangkul said she had approached hotels with the idea of using wristbands to help identify tourists lost or in trouble.
"When tourists check-in to a hotel they will be given a wristband with a serial number that matches their ID and shows the contact details of the resort they are staying in so that if they're out partying late and, for example, get drunk or lost, they can be easily assisted," Kobkarn told Reuters.
She said "electronic tagging" may be the next step, while plans to use a "buddy system" - pairing tourists with a local minder - was also being discussed.
Police in Thailand are offering a reward of more than £13,000 in their bid to catch the killers of two British tourists.
The bodies of David Miller, 24, and Hannah Witheridge, 23, were discovered on a beach on the tiny island of Koh Tao on September 15.
A bloodstained garden hoe, believed to be the murder weapon, was found nearby.
A group of Thai footballers are the latest people to be questioned by police amid fears that the hunt for the killers has stalled.
A spokesman for the Royal Thai Police confirmed that DNA samples were taken from "more than eight" footballers - who reportedly threw a late-night party at the nightclub where the victims spent their final hours - and officers were awaiting the results.
Police in Thailand say they have "fresh evidence" that two British backpackers may have been murdered out of "sexual jealousy".
David Miller, 24, and Hannah Witheridge, 23, were found dead on the island of Koh Tao last Monday.
Police Colonel Kissana Phathanacharoen said: "We have discovered fresh evidence which could lead to a new suspect who may have had a relationship or one night stand with Hannah or one of her friends or David the night before they were killed."
"We have asked the Metropolitan Police to go back and make enquiries of Hannah's friends on this matter"
He added that police could not confirm reports that David and Hannah had had a fight with a Thai man in a bar the evening they died.
The father of the British man murdered in Thailand believes his son had stepped in to help his fellow victim when they were both brutally killed on an island.
Ian Miller said it was in his 24-year-old son David's character to help, and claimed that was probably the circumstance when he and Hannah Witheridge were murdered in Koh Tao a week ago.
He told the Daily Mail: "It has become clearer and clearer that it is quite likely David was stepping in to help a girl who was in trouble.
"That would be absolutely in his character."
The family Hannah Witheridge said they have brought the body of the British holidaymaker who was brutally murdered together with a fellow tourist in Thailand back to the UK
Hannah 23, was found with severe head wounds next to David Miller, 24, on a beach on the island of Koh Tao on Monday.
We can confirm that we have now returned to the UK with our beautiful Hannah.
As a family we feel enormous relief to have Hannah back at home where she belongs.
We continue to work closely with officers to assist in the investigation and bring those responsible to justice.
Our family is broken and require time to grieve in private - as do Hannah's many friends. With the support of our fantastic family liaison officers we will make further statements as required and when we feel able.
As such, we would be very grateful for time and privacy to try and come to terms with our devastating news.
Her family said today that they had travelled to Bangkok on Tuesday to bring their "beloved Hannah" home and find out more about the investigation.
Police in Thailand said they still have not "come up with the exact number of the suspects" following the brutal murders of two British tourists, but confirmed they are looking for more than one.
Six days after the bodies of Hannah Witheridge, 23, and David Miller, 24, were found with severe head wounds on a beach on the island of Koh Tao.
A spokesman for Royal Thai Police would not confirm that DNA from Miss Witheridge's body reportedly matched that of two Asian men.
Thailand's military ruler has apologised for suggesting tourists would be unsafe wearing bikinis on the country's beaches just days after two British backpackers were found murdered.
Prayuth Chan-O-Cha was reported to say pretty women made themselves more vulnerable to attacks by wearing a bikini after Hannah Witheridge and David Miller were found murdered on the island of Koh Tao.
The comments triggered a backlash online with many taking to Twitter to voice their disgust.
Shame on you Prayuth, pretty sure girls in bikinis aren't targeted just because they aren't considered 'pretty'.
General Paryuth has since apologised, saying he had not meant to criticise anyone and said the country was safe for tourists.
He said: "I apologise that I have spoken too harshly ... I didn't mean to criticise or look down on anyone. Today I can guarantee that Thailand is still safe ... I wanted to warn (the tourists) to be careful."
Police hunting the killers of two British backpackers have carried out a number of raids on the Thai island where the pair were found murdered.
Hannah Witheridge and David Miller were discovered on a beach on Koh Tao on Monday.
Four more men are believed to have been questioned in connection with the deaths following the raids.
DNA tests have found no matches to link the two British backpackers to earlier suspects detained by Thai police.
The distraught family of murdered British backpacker Hannah Witheridge have arrived in Thailand
Relatives of the 23-year-old hugged each other as they arrived at the headquarters of the Royal Thai Police in Bangkok.
Officers have so far failed to match her DNA with any of their suspects.
Her body was found alongside fellow Briton David Miller, 24,on the island of Koh Tao on Monday. Post mortem tests have showed the pair died from head injuries.
Tests carried out on eleven Burmese migrants questioned over the murders of British backpackers David Miller and Hannah Witheridge have shown no DNA matches, Thai Police have said.
The group were arrested after bloodstains were found on some of their clothing.
