A violent confrontation erupted in Kościerzyna, Poland, involving a significant number of pseudo-fans from the Lechia Gdańsk football club. The clash occurred at an MMA club located on Traugutta Street, which is centrally positioned in Kościerzyna. Eyewitnesses reported that dozens of Lechia Gdańsk supporters barged into the venue where the players of Kaszubia Kościerzyna were training, escalating tensions in the area and drawing a police response.

The incident prompted immediate action from local law enforcement, with Pomorska Police announcing via social media that 13 individuals were initially detained. However, as the situation progressed, this number increased to 30 as police expanded their operations, implementing blockading measures to prevent further escalation of violence. This highlights the ongoing issues of football-related violence, particularly involving pseudo-fan groups, which pose significant challenges for authorities.

In a statement that accompanied the police updates, Minister Marcin Kierwiński commended the police's swift response and emphasized a policy of zero tolerance towards such aggressive behavior exhibited by fan groups. The detained individuals are being held in police detention facilities, as investigations continue into the circumstances surrounding the violent altercation and the identities of all involved.
