An estimate 100 Irish soccer fans were left without accommodation in Poznan, Poland last night after they were refused entry to the campsite they had booked and paid for.
The company which organised their accommodation, Hotelioni, said that it was making alternative arrangements for the fans.
In a statement, Hotelioni blamed the closure of the site on a media campaign against it and what it described as "hostile treatment from the authorities".
Amongst those affected were four fans from Co Donegal and two from Co Meath, who had to sleep on a concrete floor in a building at an industrial estate last night.
Before leaving Ireland, the fans had made their payments of €2,400 to the campsite operator using booking.com.
Booking.com said it was working with Hotelioni to refund customers left without accommodation.
Meanwhile the mayor of Poznan, Ryszard Gorobelny, has confirmed that three Irish people have been arrested after trouble broke out in the old square in the early hours of this morning.
In total 14 arrests were made - 10 Polish, three Irish and one Croat - for what the mayor described as minor incidents.
He added that generally the behaviour of fans has been excellent; on the first day 47,000 attended the fan zone with no arrests.
