The Guardian’s Josh Halliday has this summary of today’s developments, including details of those arrested.
Jeffrey Webb, president of the Confederation of North, Central America and Caribbean Association Football (Concacaf) and a major figure in Fifa politics, was among those detained. His predecessor, Jack Warner, was also arrested, according to the New York Times. The others held by Swiss police are: Eugenio Figueredo, a Uruguayan Association football executive and former footballer; Eduardo Li, president of the Costa Rican football federation; Julio Rocha, a Fifa development officer; Rafael Esquivel, president of the Venezuelan Football Federation; José Maria Marin, president of the Brazilian Football Confederation, and Nicolás Leoz, the former South American football president. Another suspect was named as Costas Takkas. Up to 15 officials are understood to be under investigation worldwide, so the arrests on Wednesday morning may be just the start.
