UPDATE: A British man who disappeared in Thailand almost a week ago has been found safe and well. The Foreign Office said Jordan Jacobs, from Lyneham, Wiltshire, was located by local authorities on the popular tourist island of Koh Phi Phi. A spokeswoman said: "Our embassy staff have spoken with him to check on his welfare and we will remain in contact with his family to provide any further assistance required."
The family of a British man, who disappeared in Thailand days before he was to return home, for Christmas have appealed for help to track him down, after he told them he was being held against his will and could "never see us again".
Jordan Jacobs, from Lyneham, Wiltshire, was last seen at a restaurant on the island of Ko Phi Phi Don on Saturday.
That morning he messaged his mother on Facebook saying he would never see them again and that he was sorry he couldn't have said goodbye.
The 21-year-old was urged to get in touch and a few hours later he phoned his mother telling her a Thai man would not let him leave the island.
In a Facebook post his sister Emily Jacobs said it is believed her brother accepted a free ride to Ko Phi Phi Don from a Thai man he met near a laundrette close to the Pak Up hostel, in the Krabi district of the mainland.
Later, he borrowed a phone from a Cypriot traveller and made contact with his family.
Ms Jacobs told the Mail Online: "Saturday morning my mum received a message via Facebook from my brother which basically said he can never see us again, that he is sorry he can't see us one last time, that he loved us etc.
"He was upset and said that the man wouldn't let him leave. That he was scared of him.
"This is not like my brother. Only last week he was talking about coming home for Christmas."
In a brief phone call on Monday, Ms Jacobs told the Mail her brother wouldn't tell her where he was, because he needed to "keep you all safe". He ended the call by saying that he had "said too much. I can't talk. I love you."
The missing Brit had been travelling in Australia and south-east Asia since November 2014 and was due to return home on Thursday to spend Christmas with his family. His flight was reportedly due to leave Bangkok on Wednesday.
A spokesman for the Foreign Office confirmed Jordan Jacobs had been reported missing in Thailand on December 12, and said his family were being provided with consular assistance.
In her Facebook post, Ms Jacobs said: "We are being contacted hourly by people from around the world offering to help or with information. From the bottom of my heart, Thank you for all of your generosity.
"Any information no matter how small you think it is could be could be huge. Any sightings or potential sightings. Any contact. Anything.
"We want to have him home safe."
Mr Jacobs is described as having dark hair, brown eyes and distinctive tattoos on his arms and chest.
