The National Centre against Organised Crime (NCOZ) confirmed to the Czech news agency ČTK that it is carrying out criminal proceedings. According to ČTK, FAČR is currently investigating the matter and will issue a statement once it has established all the details.
"Our department is carrying out criminal proceedings today. The submission of information is reserved for the High State Prosecutor's Office in Olomouc," said NCOZ spokesman Jaroslav Ibehej.
According to iSport.cz, Europol and Interpol are also involved, and the raid was preceded by a three-year investigation. The website reported that the police action also involved first league and youth matches.
"Since 6am, a giant crackdown has been underway, probably the biggest in the history of Czech football," it quoted from a text message sent out by FAČR chairman David Trunda to members of the executive committee.
"The overreach is especially in Moravia, 99 per cent, which concerns dozens of people."
"This is the result of the cooperation between FAČR and the police of the Czech Republic. The Ethics Committee will today start proceedings with more than 40 players, officials, referees and clubs, including clubs of the highest competition down to the fourth league plus the youth leagues," Trunda wrote, according to iSport.cz.
The FAČR boss was due to attend the induction of former national team player Přemysl Bičovský into the Hall of Fame at 9:00, but excused himself.
Olomouc chief prosecutor Radim Dragoun said several dozen people were detained and searches were carried out at their homes and other premises and land, according to the VSZ website.
The unpleasant affair for the entire Czech football movement comes just a day after the announcement of their Footballer of the Year and just three days before the start of the playoffs for participation in the 2026 World Cup.
