The president of Chile's national soccer association, Sergio Jadue, will be in the United States until May 2016 to serve as an FBI informant in the U.S. Justice Department's investigation into corruption at FIFA, according to multiple media reports. 

Local police last week served Sergio Jadue, 36, a subpoena as part of what national soccer association ANFP said was an investigation into how it allocates salaries, only hours after Jadue announced that he was taking a 30-day leave for medical reasons.

"The trip is confirmed. He traveled to Miami last night," an ANFP spokesman told Reuters  on Wednesday, without providing details about why Jadue was in the U.S.

"It's not a vacation," Spanish-language daily  El Mercurio quoted  one unidentified official as saying. "He is due back May 10 next year. Jadue is traveling as a protected informant of U.S. Justice."

The ANFP spokesman told Reuters that Jadue, contrary to local reports of his resignation, "continues to be the ANFP's president."

The spokesman added that ANFP would make an official statement later Wednesday.

The U.S. Justice Department has indicted 14 soccer officials and businessmen on charges of bribery, racketeering and money laundering.

Among them are two former presidents of the South American soccer confederation (CONMEBOL) who are fighting extradition to the U.S. as FIFA, the sport's world governing body, continues to reel from the corruption scandal.
