Thirty people have been arrested and five police vans were damaged during a second night of violence in Knurow, in southern Poland, following the death of a football fan hit by a rubber bullet fired by police.
Some 200 young men pelted the police station and officers with molotov cocktails and stones on Sunday night following the death the previous day of a 27-year-old man who was hit by a rubber bullet in clashes with the police during a Polish league football match at the local stadium.
An autopsy Monday is to reveal the cause of the man's death as prosecutors are investigating.
Fourteen policemen were hurt in clashes on Saturday.
