The family of missing Icelandic poker player Jon Jonsson have renewed their appeal for the missing 41-year-old.

Jonsson was visiting Dublin for a poker tournament with his partner, when he went missing from the Bonnington Hotel where he was staying on the northside of the city.

One month after his disappearance, the family are renewing the appeal for the missing man with the ‘Have You Seen My Brother’ campaign.

The family are said to be confident that Jonsson is alive in Ireland, but may no longer be in Dublin.

They have issued a poster with the missing man’s image and relevant information, alongside the number for Ballymun Garda Station.

A popular online gambling site, PokerScout.com, have also issued a note of caution to players to be aware following Jonsson’s appearance, just one and a half days into a visit to Dublin for a poker tournament at the Bonnington Hotel.

A statement from the site said: “While theft or robbery may not have been the cause of Jonsson’s disappearance, the case is a good reminder for poker players.

“Poker players necessarily carry generous amounts of cash, which can make them an inviting target for criminals.”

Jonsson was last seen in Whitehall on February 9 at 11:05am on CCTV footage at McGettigan’s bar, exiting onto the Swords Road and heading north past Highfield Hospital.

Anyone with information is asked to contact Ballymun Garda Station at 01 6664400, the Garda Confidential Telephone Line at 1800 666 111, or any garda station.
