Jay Slater's mum sent horror Snapchat message saying 'kiss your son goodbye' amid kidnapping fears

During his final call to his friend Lucy at 8am local time on Monday, the 19-year-old said his phone had only one per cent battery, he was thirsty and he did not know where he was.

His last location shows the Rural de Teno Park - an area popular among hikers. He has not been seen since.

Slater’s mother, Debbie Duncan, flew out to Tenerife, after being told by police that it was the “best thing to do”.

About 10 minutes after the plane touched down, Duncan received a horrific Snapchat message which read: “Kiss goodbye to your boy, you’re never going to see him again, he owes me a lot of money.”

Her eldest son Zac managed to screenshot the message before it disappeared, and she quickly alerted the police.

She believes that Slater - who was due to fly home on a flight tomorrow morning - is being held against his will and has a feeling that “something bad” has happened.

Duncan, who has been staying on the south of the island, where her son had been holidaying, told The Sun: “I haven’t slept since all this began and I’ve no plans to go up to the search site right now.

“I just want to be here for if he does turn up but I’ve got a bad feeling. I’m being warned there’s a lot of bad people in Tenerife.

“I just think he’s being held against his will. He’s not a stupid lad. He wouldn’t have gone walking down bloody mountains.”

Duncan has also revealed that she has received prank calls from trolls who have set up fake GoFundMe pages in her son’s name.

The family of the apprentice bricklayer have since begged kind strangers not to donate to the bogus pages.

She said: “Some of the phone calls I've been getting have been horrible. I just don't know why people would want to do things like this.”

A Facebook group set up by his family posted: “This is the only official ‘missing Jay Slater’ Facebook group. Jay's mother DOES NOT want a GoFundMe set up so DO NOT donate to one!!”

Various members replied to say there are “about seven” fake fundraisers circulating that some people have donated “£100+” to.

It is understood that all the bogus pages have been taken down as of this morning.

The teenager was last spotted wearing a white t-shirt, shorts, and trainers, as well as carrying a black bag.

In a statement, a spokesperson for the Foreign, Commonwealth & Development Office said: “We are supporting the family of a British man who has been reported missing in Spain and are in contact with the local authorities.”
