Gardaí say they have "serious concerns for the safety" of an Icelandic man who has been missing in Dublin for over two weeks.

Jon Jonsson was last seen in the Whitehall area of the city at around 11am on Saturday 9 February.

The 41-year-old left the Bonnington Hotel and walked on the Swords Road pass the entrance to Highfield Hospital.

He had been in Ireland with his fiancée for a poker tournament and for a holiday.

Today, gardaí renewed their appeal for the public’s assistance in trying to trace the father of four.

Jon is described as being 1.82m (6ft) tall, of medium build, with short brown hair.

When last seen he was wearing a black padded jacket.

A new image, taken from CCTV footage on the morning he went missing, has been released.

The Garda Air Support Unit and Dog Unit carried out a search in the area around where he was last seen, while his family and friends were joined by local people in a further search of the location yesterday.
