In Kościerzyn, located in the Pomeranian region of Poland, approximately 50 masked pseudofans from two conflicting football clubs stormed into a school gymnasium where martial arts training was taking place. The incident, which occurred on Monday evening around 8 PM, involved a group of men who were attacked during their training session by the intruders wearing balaclavas. Witnesses reported feeling fearful for their safety as the situation escalated dangerously.

Local authorities quickly responded to the scene as police were dispatched to control the violence. In total, 30 people were apprehended in connection with the brawl, while ten individuals suffered injuries needing medical assistance. The aggressive nature of the pseudofans raised significant concerns regarding safety at public events, especially within community spaces such as schools.

The attack underscores not only the ongoing tensions between rival football factions but also highlights the potential risks that innocent bystanders face during such altercations. The police investigation is expected to delve deeper into the affiliations of those involved and how to prevent similar incidents in the future, which raises the need for stricter regulations around sports-related violence.
