The family of an Icelandic tourist, missing in Dublin since February 9, have made an emotional appeal for his safe return.
Jón Throstur Jonsson had been in the city with his fiancé to take part in a poker festival, but went missing only one day into his trip.
The 41 year-old was last seen at around 11 am in the Whitehall area of Dublin on February 9.
He is 1.84m (6ft) tall, with short brown hair and of medium build. He was last seen wearing a black padded jacket.
His distraught sister Thorunn took to social media to desperately appeal for information.
She said: “I have been asking myself how a person can just vanish in broad daylight.
"Jón has always been independent and left home early. He is a kind and gentle soul, extremely intelligent, reserved yet outgoing. Non-political. Non-religious.
"A family man and a father/step-father of four strong children of 11, 11, 16 and 17 years. Jon is the most reliable and trustworthy person I know and I am certain that if you asked anyone around him they would say the same thing. They would also tell you how odd this all is.
"It doesn't sound like him to just up and leave. And we don't believe that he did either. But we can't tell you what happened because we don't know. And we can't sit around and guess. It will drive us mad."
Thorunn described Jón as a kind man who paid for her college graduation dress because she couldn't afford one.
She added: "When I turned 30 he paid for my first tattoo. Our first-born children were born six months apart and his and his then wife's Nína's house was the second home to me and my son.
"Many times during these past 10 days I have felt like I should call him because I'm going through a hard time and need to speak to him.
"But two seconds into the thought I realise the error. I can't call Jón. I feel like I'm not here. Even as I write this I have this feeling of disconnect. I feel like this isn't happening. How can this be happening? Where is my brother? I need to find my brother!"
A GoFundMe appeal has also been launch to assist in the search.
Some of Jón's siblings arrived in Dublin this week to help with the search. They are asking for volunteers to help with a search of the area he was last seen.
