Several FIFA officials, including vice-president Jeffrey Webb, have been arrested on suspicion of corruption in dawn raids at a Zurich hotel.
The members of world football’s governing body were held by Swiss police at the US Department of Justice’s request.
They are suspected of having received millions of US dollars in bribes.
Swiss authorities have also begun criminal proceedings into the awarding of the 2018 and 2022 World Cups.
FIFA President Sepp Blatter, seeking a fifth term in charge when he stands for re-election on Friday, is not one of those arrested.
Nine current and former FIFA officials were named on the indictment, which New York attorney General Loretta Lynch says “alleges corruption that is rampant, systemic, and deep-rooted both abroad and here in the United States”.
Jeffrey Webb: current FIFA vice-president
Jack Warner: former FIFA vice-president
Eduardo Li: Costa Rican federation president
Julio Rocha: current FIFA development officer
Costas Takkas: current attaché to the Concacaf president.
Eugenio Figueredo: current FIFA vice-president
Rafael Esquivel: current Conmebol executive committee member
José Maria Marin: current member of the FIFA organising committee for the Olympic football tournaments
Nicolás Leoz: former FIFA executive committee member and Conmebol president.
The twin corruption probe includes a separate criminal investigation into how the World Cups Russian 2018 and Qatar 2022 were allocated.
Authorities will question 10 executive committee members who took part in the votes in December 2010.
