Ukrainian police say they have detained 52 people for fan violence ahead of Wednesday's Champions League game between Shakhtar Donetsk and Dutch club Feyenoord.
Police say they arrived at a bar in the city of Kharkiv where ''a conflict had occurred between Dutch and Ukrainian fans'' and took 52 people to a police station for questioning.
Police say windows were broken and the interior of the bar was damaged.
Ukraine is hosting this season's Champions League final but has a record of soccer-related violence. Hundreds of Ukrainian and Turkish fans clashed in Kiev around a game last year.
