In Kościerzyna, in the Pomeranian Voivodeship, a significant disturbance unfolded when a large group of individuals, identified as pseudo-fans, forcibly entered a sports facility where athletes were training. The clash broke out as these individuals engaged in a brawl with the athletes present, creating a chaotic scene that local authorities struggled to manage. With dozens of people involved in the scuffle, the local police initially struggled to contain the situation until reinforcements from the Gdańsk Prevention Police arrived to help restore order.

Reports indicate that approximately thirty individuals have been arrested in connection with the incident, and authorities warn that this number could rise as investigations continue. Following the assault, the assailants dispersed rapidly, prompting a police manhunt for those involved. Eyewitness accounts from Radio Zet reveal that several individuals sustained injuries during the brawl, with one man reported to be in severe condition and requiring hospitalization in Gdańsk. However, the police have not provided a final count of the injured, as new cases continue to emerge.

The incident has drawn significant attention and condemnation from officials, including a minister who referred to the aggressors as "bandits." This event highlights ongoing issues surrounding violence associated with pseudo-fan groups in Poland, suggesting a need for stricter measures to prevent similar occurrences in the future. The implications of this violence are far-reaching, affecting community safety and the reputation of sports events across the country.
