PEC Zwolle and KNVB Launch Crackdown Following IJsselderby Disorder

The fallout from the latest IJsselderby is intensifying as PEC Zwolle and the Royal Dutch Football Association (KNVB) move to identify supporters who disrupted the high-stakes clash against Proceed Ahead Eagles on April 5, 2026.

Following reports of prohibited face-covering clothing and the use of fireworks, PEC Zwolle has confirmed This proves conducting a comprehensive investigation into the behavior of its away fans. The club has already secured extensive image material and is now coordinating with a specialized KNVB task force to ensure those responsible face significant penalties.

Chaos and Delays in Deventer

The match, held in Deventer, was marred by disorder before a ball was even kicked. PEC Zwolle supporters arrived wearing clothing designed to conceal their identities, a direct violation of stadium safety regulations. The situation escalated when fireworks were detonated in the away section, forcing officials to clear the area entirely for security reasons.

The disruption caused a massive delay to the kickoff, with the match eventually starting 97 minutes late. Because of the security breach, the game was played without the presence of any PEC Zwolle away supporters. On the pitch, the tension did not favor the visitors, as Go Ahead Eagles secured a dominant 5-0 victory.

High-Quality Evidence and the KNVB Task Force

PEC Zwolle officials have provided an update on the investigation, stating that they have successfully retrieved and secured all relevant footage. This includes images from the supporters’ departure in Zwolle, their arrival in Deventer, and recordings from within the away section.

The club noted that a preliminary analysis shows the image quality is high, leading management to believe that the first group of misbehaving individuals will be identified shortly. To accelerate this process, the KNVB is deploying a specialized task force. Whereas this team does not provide additional camera hardware—as the responsibility for surveillance lies with the clubs—they provide the expert manpower necessary to analyze vast amounts of footage and identify individuals who may have been obscured by face coverings during the event.

For those unfamiliar with the process, the investigation relies on “cross-referencing” footage. Investigators gaze at images from the mandatory bus combinations and stadium entrances—where fans are less likely to be wearing masks—and match those identities to the individuals seen causing disorder inside the grounds.

Severe Penalties for Face Coverings and Fireworks

The KNVB has issued a stern warning regarding the consequences for fans caught violating these rules. The penalties are designed to be a strong deterrent against hooliganism in Dutch football.

• Possession of face-covering clothing: A national stadium ban of nine months and a fine.
• Wearing face-covering clothing: A national stadium ban of 18 months and a fine.
• Fireworks: Possession or detonation of fireworks carries additional penalties that are added to the bans mentioned above.

A national stadium ban is a severe sanction, effectively barring an individual from attending any professional football match within the Netherlands for the duration of the sentence.

The Intensity of the IJsselderby

The rivalry between PEC Zwolle and Go Ahead Eagles, known as the IJsselderby, is one of the most volatile in the Netherlands. Named after the IJssel river which flows through both Zwolle and Deventer, the derby is characterized by deep-seated animosity that evolved significantly during the 1980s and 90s.

While the clubs may not always occupy the same tier of the league, the matches are consistently high-risk. Security forces, including the Mobile Unit (ME), are routinely deployed in large numbers to prevent hooligan violence. The recent events in Deventer underscore the ongoing struggle to maintain order during what has been described by some observers as one of the grimmest derbies in the country.

Investigation Timeline and Next Steps

The investigation is currently in the identification phase. With the KNVB task force joining the effort this week, the club expects a rapid turnaround in naming and penalizing the offenders.

PEC Zwolle has made it clear that the safety of all spectators and the reputation of the club are paramount, and they will not tolerate actions that lead to match delays or the exclusion of their fans from the stadium.

The next official update on the identification process is expected as the KNVB task force completes its initial review of the secured footage.
