Ten Poland and Croatia football fans have been fined for violence and public order offences in the Euro 2012 host city of Poznan, while one Irish fan was fined for drink-driving, a court official said.
The fines relate to trouble at the Croatia-Republic of Ireland Group C match on Sunday, which the Croats won 3-1.
Two Croats who invaded the pitch were each fined 2,000 zloty (463 euros) and were banned from the Municipal Stadium in Poznan for three years, said court spokeswoman Agnieszka Weichert-Urban.
One of the pair ran on to the pitch and kissed Croatia coach Slaven Bilic while celebrating.
Two other Croat supporters were fined for involvement in a fight in the old city of Poznan and the fifth was told to pay 1,000 zloty for breaking a car window.
Five Poles who were involved in the same fight were fined between 800 and 2,400 zloty. One of them also received a six-month suspended prison sentence.
One Irish fan arrested for being over the legal alcohol limit for driving was fined 800 zloty.
Some 30,000 Irish and 10,000 Croat fans were at the match.
