He was questioned as a witness and released shortly afterwards in May 2020.What Vincic said after his releaseHe later spoke to Slovenian outlet Vecer and maintained that he had no connection to those under investigation."I accepted an invitation to lunch, which turned out to be my biggest mistake. I regret it. I was sitting at a table with my company, all of a sudden the police came and what happened, happened.I have nothing to do with the group that was arrested and detained, nor do my business partners,” Vincic clarified.Aftermath of police raidThe case continued after his release. Maksimovic later admitted guilt to a charge of international enticement to prostitution, with prosecutors proposing a one-year prison sentence.During the raid, police reportedly detained 35 people—26 men and nine women—and recovered four packets of cocaine, 10 pistols, three protective vests, and more than 10,000 euros in cash that had been converted from multiple currencies.Vincic’s road to World Cup finalDespite that difficult chapter in his career, officiating the World Cup final represents one of the biggest assignments of Vincic's career.It is not, however, the first time he has been trusted with a high-profile fixture. The Slovenian referee previously officiated the 2024 UEFA Champions League final, where Real Madrid defeated Borussia Dortmund.The only Argentina match Vincic has overseen came during the 2022 World Cup, when Lionel Messi and his teammates suffered a shock defeat to Saudi Arabia in the group stage.Also read: Argentina President Javier Milei reveals superstition behind not attending World Cup final vs SpainAt this year's World Cup, Vincic has already handled three matches, overseeing Mexico's Round of 32 victory over Ecuador, Brazil's draw against Morocco, and Algeria's win over Jordan.
