Bus with Biris Norte members was stopped by the police on the way to Rotterdam. Dutch police arrested all of the ultras because they carried weapons with them.
Fans stayed the whole night in police station. Only when the match between Feyenoord and Sevilla from Europa League finished, after payment of 50 euros to a fine, every fan was able to access the bus waiting outside.
