The parents of a 21-year-old Irish soccer fan, who has been missing in Poland since Saturday night, have made an emotional appeal for help in finding him.

James Nolan from Blessington in Co Wicklow, disappeared on a night out in Bydgoszcz, a town 130km north east of Poznan.

Polish police along with Irish consulate staff, are involved in the search.

Mr Nolan, an engineering student, set off for Poland in a camper van with a group of friends 11 days ago.

After attending the first match in Poznan, they travelled to Gdansk for last week's Spain game.

They then began returning to Poznan for tonight's fixture, but stopped in a town called Bydgoszcz on Saturday night.

At some stage that night, for no known reason, James became separated from his friends, and has not been seen since.

Back home in Blessington, his family and friends have gathered at the home of parents Essie and Jimmy, anxiously awaiting news.

His parents say that they last spoke to him on Saturday and he said he would call for Father's day yesterday, but did not.

His father Jimmy has asked anyone who knows anything about his whereabouts, to contact them or the gardaí. He said he and Mr Nolan's mother Essie are hoping he will turn up safe and well, but are growing very concerned.

Mr Nolan's uncle, Pat, said it was very out of character for his nephew to disappear like this.

He said his nephew is a sensible fellow, who had texted or phoned home from Poland almost every day since setting off on 7 June.

He also said they knew Mr Nolan's phone was not working on Saturday, but he had been in touch Saturday evening before he disappeared.

He added that Mr Nolan withdrew money from his bank account on Saturday evening, but has not taken any more money out since.

Anyone with information can contact the Irish consulate in Poznan on 0048 880529105, gardaí or the Department of Foreign Affairs here on 1890 426700.

A department spokesperson said that over the course of Euro 2012, a number of Irish fans have been reported missing, but have turned up after a day or so.
