Supporters of the local Concordia Knurow team yesterday stormed onto the pitch during the first half against Ruch Radzionkow, with the home team trailing 4-1.
A 27-year-old man was struck by a rubber bullet on the neck when police fired at the attackers. More rioting broke out around the hospital, where the man was pronounced dead.
Tomasz Pitsch, deputy director of the Knurow hospital, said "We are shaken by the fighting we witnessed," which included stones and molotov cocktails. "You can see the marks on the hospital walls."
An autopsy of the victim is planned for tomorrow as prosecutors begin an investigation into the circumstances of his death. A separate probe was opened today into the rioting near the hospital.
