The designation of the Slovenian Slavko Vinčić as the referee for the 2026 World Cup final between Spain and Argentina has brought back to the forefront an off-field incident that marked his career six years ago.
In May 2020, the referee was temporarily detained during a police raid in Bosnia and Herzegovina against an alleged organization involved in prostitution, drug trafficking, and illegal possession of weapons. However, after giving a statement, he was released and never charged with any crime.
The operation, known as "Kristal", generated enormous international repercussions and led to numerous headlines that, in some cases, confused the referee's presence at the scene with criminal involvement that never occurred.
A large-scale police operation against an alleged criminal network
The events occurred on May 28, 2020, on a property located in the vicinity of Bijeljina, in the entity of Republika Srpska, within Bosnia and Herzegovina.
The police carried out a broad operation against an alleged organization linked to prostitution, drug trafficking, and illegal possession of weapons. During the intervention, approximately 35 people were detained, including 26 men and nine women.
In the searches, authorities reported finding cocaine, firearms, bulletproof vests, mobile phones, laptops, and cash, items that became part of the investigation opened against several of the main suspects.
Why was Slavko Vinčić there?
The presence of the Slovenian referee on the property surprised both sports media and authorities.
As Vinčić later explained to Slovenian media, he had traveled to Bosnia to attend a business meeting and, after concluding that meeting, accepted an invitation from several people to attend a meal at a private property.
The referee stated that he did not know who most of the attendees were and claimed that he never imagined he could be in a place that was being investigated by the police.
In his statements, he even described what happened as "the biggest mistake of my life", insisting that his presence on the property was the result of an unfortunate coincidence.
He testified as a witness and was released
One of the aspects that generated the most confusion during those days was the referee's legal situation.
It is true that Vinčić was detained by the Police during the operation and transferred to make a statement. However, information subsequently published by Bosnian and Slovenian media agrees that he was interrogated as a witness and not as a member of the alleged organization under investigation.
After testifying, the referee was released and returned to Slovenia.
To date, there is no record of him being charged, prosecuted, or formally accused of any of the crimes that Bosnian authorities were investigating.
The investigation focused on other suspects
The police operation was primarily directed against several individuals suspected of belonging to a network dedicated to the exploitation of prostitution and other criminal activities.
Among the names that gained significant media notoriety was that of the Serbian influencer Tijana Maksimović, publicly known as "Tijana Ajfon", whose arrest concentrated a large part of the news coverage in the Balkans.
Subsequent judicial proceedings focused on the main individuals investigated for the organization, while Vinčić's name disappeared from the proceedings as no evidence was found to attribute his participation in the investigated events.
From controversy to refereeing major European finals
Far from affecting his refereeing career, the 2020 episode did not prevent Vinčić from continuing to receive the trust of UEFA and FIFA.
Two years later, he was appointed to referee the 2022 Europa League final between Eintracht Frankfurt and Rangers. In 2024, he refereed the Champions League final between Real Madrid and Borussia Dortmund at Wembley Stadium, considered one of the most prestigious matches on the international calendar.
He also participated as a referee in the Qatar 2022 World Cup and has been one of the referees chosen for the 2026 World Cup.
The appointment for the final between Spain and Argentina represents the greatest recognition of his entire professional career and confirms that, for international football organizations, the Bosnian episode did not condition his sporting career.
What really happened: established facts and what is not proven
The case of Slavko Vinčić is an example of how news of enormous impact can become simplified over time.
The established facts are that the referee was at the property where the police operation took place, that he was detained to make a statement, and that he was subsequently released without charges.
On the contrary, there is no record that he was accused, prosecuted, or convicted, nor that the judicial authorities attributed his participation in the alleged criminal network that motivated operation "Kristal".
Therefore, the most accurate way to describe that episode is to state that Vinčić was temporarily detained during a large-scale police operation, questioned as a witness, and released without any criminal action being taken against him.
