The family of Icelandic tourist Jon Jonsson say they're not giving up their search.

Jon, who was in Dublin before his disappearance, has now been missing for over a month.

The 41-year-old was last seen after leaving the Bonnington Dublin hotel in North Dublin at 11:05am on Saturday the 9th of February.

CCTV recorded him at the exit of Highfield Hospital heading northbound on Swords Road on foot towards Collins Avenue.

His family says an extensive search has been carried out in the Whitehall area where Jon was last seen.

However, it's now believed to be "highly unlikely" he's in that area.

Jon left the hotel without his passport or any other government-issued identification.

According to his family, it's unlikely that he left Ireland.

However, they're not ruling out the possibility as he could have travelled to Northern Ireland or Britain.

Countrywide campaign

The family's now encouraging people across Ireland to take part in their 'Have you seen my brother campaign'.

They're asking people to display their missing person posters wherever possible.

David Karl Wiium, Jon’s brother, explained: “We are not giving up.

"We are so incredibly grateful for the support and help we have received from the people of Ireland and hope this countrywide campaign will assist in helping us bring Jon home”

Jon's described as being six foot tall with brown hair and grey-blue eyes.

When last seen he was wearing black jeans, a black padded jacket, a black T-shirt with a printed white message and picture on the front, and black sneakers with a white base.

Anyone who sees or has seen Jon can contact Ballymun Garda Station on 01-666-4400.

The family's also set up a hotline on 089-443-1263 for anyone who thinks they might have spotted Jon.
