GENEVA (AFP) - Swiss authorities on Wednesday said a seventh top football official was arrested following a US request in a corruption probe that has sent Fifa into turmoil.

Football's top body, based in the Swiss city of Zurich, has been plagued by corruption allegations over decades but Wednesday's shock arrests were the biggest blow to its reputation so far.

"In the course of the morning, a further wanted soccer official has been arrested further to a request from the United States," the attorney-general's office said, naming a seventh man.

It said the seven officials being held were Eugenio Figueredo, Fifa vice president and executive committee member from Uruguay; Costa Rican Eduardo Li, who was supposed to join the Fifa executive committee; and Brazilian football federation chief Jose Maria Marin, a member of Fifa's organising committee for the Olympic football tournaments.

The others were Nicaraguan Julio Rocha, Costas Takkas, attache to the Concacaf president, and Cayman Islands' Jeffrey Webb, the Fifa vice president and executive committee member, and Rafael Esquivel, president of the Venezuelan Football Federation.

The arrests follow a US probe into a bribery and kickback scheme spanning two decades.

After the Zurich arrests, the US justice department announced conspiracy and corruption charges against nine Fifa officials and five business executives.
