Police say a 21-year-old Irish soccer fan has gone missing while in Poland for the European Championship.

James Nolan of Blessington, County Wicklow, went missing early Sunday in the northern city of Bydgoszcz after watching games in fan zones and visiting local bars with a group of Irish friends.

Police spokeswoman Monika Chlebicz said Tuesday that friends realized that Nolan did not return to their hotel, and he is not answering calls. Police are searching the city and have posted photos of Nolan on their website.
