Woźniak caught up to a member of the group, the 13-year-old Przemysław Czaja and repeatedly hit his head and neck using his baton.
News about the incident spread quickly around the city and next day, on Sunday, January 11, a group of supporters of the two Słupsk's sports clubs – Czarni and Gryf, gathered in the morning on Szczecińska Street, to erect a cross there.
At about 4 p.m. the prosecutor issued a statement stating that the victim stumbled while running away, and hit his head against a trolley bus traction post, which caused the death.
For the next three days Słupsk was marred by violent fights, and as local police department was unable to tame the rioters, help was called from neighboring cities.
In September 2005 the Circuit Court in Gdańsk decided that the family of the victim would get compensation in the amount of 300 000 PLN (around $100 000), paid by the Słupsk Police Department.
