Six soccer officials, including some high-ranking members of world governing-body FIFA, were arrested by Swiss police on May 27 and detained pending extradition to the United States .
The arrests were made shortly after dawn at a Zurich hotel where FIFA officials are staying ahead of this week's FIFA presidential election.
The Swiss Federal Office of Justice (FOJ) released a statement saying the six officials, who were not formally named, were suspected by US investigators of having received or paid bribes totaling millions of dollars.
The FOJ also confirmed that FIFA president Sepp Blatter was not among those arrested.
"The US Attorney's Office for the Eastern District of New York is investigating these individuals on suspicion of the acceptance of bribes and kickbacks between the early 1990s and the present day," the statement said.
"The bribery suspects -- representatives of sports media and sports promotion firms -- are alleged to have been involved in schemes to make payments to the soccer functionaries -- delegates of FIFA and other functionaries of FIFA sub-organizations -- totaling more than US$100 million."
The New York Times , citing anonymous law enforcement officials, said the US federal charges include racketeering, money laundering and wire fraud and span two decades of misconduct in soccer's world governing body.
More than 10 officials were expected to be indicted, but not all were in Zurich , the newspaper reported.
Most of the officials are in Switzerland for the FIFA Congress , where Blatter faces a challenge from Jordan 's Prince Ali Bin Al Hussein in a presidential election on May 29 when the Swiss administrator will attempt to secure a fifth term at the helm.
FIFA did not make any immediate comment on the arrests.
The New York Times said more than a dozen plain-clothed Swiss law enforcement officials arrived at Zurich 's Baur au Lac hotel early on May 26, took keys from the registration desk and headed up to the rooms.
One FIFA official was led by the authorities from his room to a side-door exit of the hotel, the Times said, adding that officials from the body's powerful executive committee were being targeted.

"We're struck by just how long this went on for and how it touched nearly every part of what FIFA did," the Times quoted an unnamed law enforcement official as saying.
"It just seemed to permeate every element of the federation and was just their way of doing business. It seems like this corruption was institutionalized."
The Times said much of the enquiry was focused on the CONCACAF region, which governs soccer in the North America , Central America and the Caribbean .
The confederation's former boss Jack Warner was regularly dogged by accusations of corruption before he resigned in 2011, putting an end to investigations of the Trinidadian.
Prosecutors expected to announce the case at a news conference at the Brooklyn US attorney's office, which is leading the investigation on May 26, the Wall Street Journal said in a separate report.
US Attorney General Loretta Lynch , Federal Bureau of Investigation Director James Comey and Internal Revenue Service criminal chief Richard Weber were expected to appear in Brooklyn to announce the case, the WSJ said.
The reports offer a fresh blow to the credibility of FIFA, which has suffered repeated accusations of wrongdoing over the bidding process for the 2018 and 2022 World Cups, which were awarded to Qatar and Russia respectively.

FIFA appointed an independent investigator to look into the allegations and though a summary of his report found some wrongdoing on the part of the Qatari and Russian bid committees, FIFA's ethics judge concluded it was not enough to question the entire process.
The investigator, former attorney Michael Garcia , subsequently resigned from his role in December after criticising the handling of his report.
Damian Collins , the British MP who founded the reform group New FIFA Now, said the news was hugely significant for FIFA and could have a massive impact on the governing body.
"The chickens are finally coming home to roost and this sounds like a hugely significant development for FIFA," he told Reuters by telephone.
"It proves that Sepp Blatter 's promises over the last few years to look into corruption at FIFA have not materialised and because he has totally failed to do this, it has been left to an outside law enforcement agency to do the job and take action."
