• Swiss Federal Office of Justice approves extradition request • Uruguayan among seven officials arrested in dawn raid in May

The extradition of the former Fifa vice-president Eugenio Figueredo to the United States to face corruption charges has been approved by Swiss authorities.

The Uruguayan, a former president of the South American confederation Conmebol, was one of the seven officials from football’s world governing body arrested at the request of US authorities in dramatic dawn raids in Zurich on 27 May in the buildup to this year’s Fifa congress.

Figueredo is accused of receiving bribes worth millions of dollars from a Uruguayan sports marketing company in connection with the sale of marketing rights to the Copa América tournaments in 2015, 2016, 2019 and 2023. He is also alleged to have acquired US citizenship fraudulently by submitting forged medical reports in 2005 and 2006.

A statement from the Swiss federal office of justice, which approved the extradition, confirmed Figueredo had 30 days to appeal against the ruling to the Swiss federal criminal court.

Another of those arrested in Zurich on 27 May – Jeffrey Webb, a former president of the Concacaf confederation representing North American, Central American and Caribbean countries – has already been extradited to the US.

The US and Swiss attorneys general staged a news conference on Monday to provide updates on their separate inquiries into allegations of corruption at Fifa.

Michael Lauber, the Swiss justice head, confirmed his country’s authorities are investigating a World Cup television rights contract signed off by Fifa president Sepp Blatter that was sold to former Fifa official Jack Warner for a fraction of their true value.

Lauber said that Fifa had sent prosecutors its explanation for the contract sold to the Warner-controlled Caribbean Football Union (CFU) for $600,000 – Warner’s company later sold them on for an £11m profit.

Meanwhile, the US attorney general, Loretta Lynch, announced fresh arrests and charges are likely as a result of the separate FBI investigations into the scandal. Lynch, speaking at the same news conference as Lauber, said new charges and arrests against “individuals and entities” were expected.

Lauber also revealed that assets including flats in the Swiss Alps and western Switzerland had been seized by his investigators, on suspicion of being used for money-laundering purposes, and that 121 different bank accounts have been brought to the attention of the investigating task force.

In May, the US Justice Department of Justice announced indictments against 18 people on football-related corruption charges – four have pleaded guilty to charges.

Lynch said on Monday: “Separate and apart from the pending indictment our investigation has expanded since May. The scope of our investigation is not limited and is following the evidence where it leads. We do anticipate pursuing additional charges against individuals and entities.”

Asked if Blatter was under investigation or if it might interfere with his travel plans – the Fifa president did not travel to the women’s World Cup in Canada in June following the arrests in May – Lynch added: “I’m not going to comment on individuals and I am not able to give you information about Mr Blatter’s travel plans.”
