The family of a British man who has disappeared in Thailand has appealed for help to track him down.
Jordan Jacobs, from Lyneham, Wiltshire, was last seen at a restaurant on the island of Ko Phi Phi Don on Saturday and his family is increasingly concerned for his welfare.
The 21 year old has made contact since then but his sister Emily Jacobs said he was "upset".
In a Facebook post, she 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 another 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 told her he had "said too much" and "can't talk".
A spokesman for the Foreign Office said: "We can confirm that a British national, Jordan Jacobs, was reported missing in Thailand on 12 December. We are providing consular assistance to the family."
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.
