Swiss police arrested several current and former FIFA officials early on Thursday as part of a corruption investigation into the world football governing body.
Zurich police said they made the arrests on the order of Swiss authorities but gave no further detail about the arrests.
"They are being held in custody pending their extradition [to the US]," the Swiss Federaal office of Justice (FOJ) said in a statement confirming the arrests of two FIFA officials.
"According to the US arrest requests, they are suspected of accepting bribes of millions of dollars," the statement said.
US Federal Bureau of Investigation (FBI) and Swiss prosecutors have been leading parallel corruption investigations into FIFA that led to arrests of 14 people including current and former FIFA vice presidents.
“FIFA became aware of the actions taken today by the US Department of Justice. FIFA will continue to cooperate fully with the US investigation as permitted by Swiss law, as well as with the investigation being led by the Swiss Office of the Attorney General,” FIFA said in a statement on Thursday.
The investigation alleges high ranking FIFA officials took bribes for the hosting allocation of 2018 and 2022 World Cups.
FIFA President Sepp Blatter, UEFA President Michel Platini and FIFA Secretary General Jerome Valcke were suspended from football for 90 days by FIFA ethics committee in October, although they have not been criminally charged.
Blatter have said he resigned his post days after he was elected for a new term and elections to elect a new president will be held in February 2016.
Speaking to TRTWorld in exclusive interviews, FIFA Presidential Candidate Jerome Champagne and Spokesperson of Sepp Blatter Klaus Stoehlker both said Blatter is not corrupt.
