(CNN) A former FIFA official being held in Switzerland as part of a corruption scandal has been extradited to the United States, officials said Thursday.

No court appearance has been scheduled, the source said.

Earlier, the Swiss Federal Office of Justice said a FIFA official had been extradited, but it didn't name the official. The official was handed over to U.S. police escorts in Zurich.

Webb, 50, was banned by FIFA, which has headquarters in Switzerland, from "football-related activities," after he was indicted in May in the United States. He had been on the governing group's executive committee since May 2012.

CONCACAF dismissed Webb, who is from the Cayman Islands, from his post as president of the organization after the FIFA scandal broke.

Earlier this month, U.S. officials requested the extradition of seven high-ranking FIFA officials arrested in Switzerland in May. They are suspected of taking bribes worth over $100 million in connection with soccer tournaments.

A Swiss probe into corruption allegations surrounding the next two World Cups has grown to include 81 acts of suspicious financial activity now under investigation, Andre Marty, a spokesman for the office of the attorney general, told CNN via email in early July.

He confirmed that all reports were in relation to the ongoing investigation into the allocation of the 2018 -- scheduled to be held in Russia -- and 2022 -- in Qatar -- editions of the World Cup, FIFA's flagship tournament.

Calls this month by CNN to the Qatar 2022 Supreme Committee for Delivery and Legacy, the organizing committee for the 2022 tournament, went unanswered, and at the time of writing the Football Union of Russia had not responded to CNN requests for a statement.

Both Russia and Qatar, however, have publicly denied any wrongdoing with regards to the bidding processes of the two tournaments.

Expanded investigation

The investigation was originally focused on 53 cases, Michael Lauber, the Swiss attorney general, said in June.

Lauber also said , in announcing the initial cases, that he was unconcerned if the investigation produced "collateral damage" in terms of the two countries' right to host their respective tournaments.

Should instances of corruption be proven, the bidding process for the next two World Cups could be reopened, senior FIFA official Domenico Scala has previously said.

Hide Caption 7 of 11 Photos: Sepp Blatter: A controversial leader Rotten eggs? – In December 2010 Blatter insisted that FIFA was "not corrupt ... there are no rotten eggs" despite two of his executive committee members -- Amos Adamu, pictured, and Reynald Temarii -- being suspended for accepting bribes in the lead-up to the vote for awarding hosting rights for the 2018 and 2022 World Cups.

Hide Caption 10 of 11 Photos: Sepp Blatter: A controversial leader We need to talk about Kevin – In January 2013, AC Milan midfielder Kevin-Prince Boateng led his team off the pitch after being subjected to racist chanting.

"I don't think you can run away, because eventually you can run away if you lose a match," he said in an interview with a newspaper in the UAE. "This issue is a very touchy subject, but I repeat there is zero tolerance of racism in the stadium; we have to go against that." Others, like AC Milan president Silvio Berlusconi, have disagreed with him. "I am of the opposite view (to Blatter)," said Berlusconi. "I thanked and congratulated my players for their decision to leave the field." Hide Caption 11 of 11

The Swiss investigation is proceeding alongside a probe launched by the U.S. Justice Department. The scale of the two operations was brought to light when several high-profile officials were arrested in May as part of an early-morning raid at a luxury hotel in Zurich ahead of FIFA's world congress.

FIFA president Sepp Blatter, who was re-elected to a new five-year term just days after his executive ranks were decimated by the arrests, later announced he would be stepping down once a successor could be found, though he has not been arrested or indicted.

"Culture of corruption"

Richard Weber, head of the IRS criminal investigation division, told reporters following the arrests that the defendants "fostered a culture of corruption and greed."

"This really is the World Cup of fraud, and today we are issuing FIFA a red card," he said.

FIFA officials are accused of taking bribes totaling more than $150 million and in return providing "lucrative media and marketing rights" to soccer tournaments as kickbacks over the past 24 years.

The news of the widened investigation comes only days after former FIFA executive-turned-whistleblower Chuck Blazer was banned from all football-related activities for life by FIFA's ethics committee.

He had previously pleaded guilty to a string of charges brought by U.S. prosecutors, including racketeering, wire fraud, money laundering and income tax evasion in 2013.
