Expands U.S. probe into football's world governing body

(CNN) Federal prosecutors in the United States on Thursday announced criminal charges against 16 FIFA officials, alleging they were part of a 24-year scheme to enrich themselves while overseeing the world governing body of soccer.

The 92-count indictment, which includes charges of racketeering, money laundering and wire fraud, expands a corruption case that began in May with charges against 14 officials associated with FIFA and related sports marketing companies.

The announcement came the same day Swiss police arrested two FIFA officials on suspicion of accepting "millions of dollars" in bribes, according to a statement from the Swiss Federal Office of Justice.

Alfredo Hawit, the president of CONCACAF, the governing body for North and Central America as well as the Caribbean, and Juan Angel Napout, president of CONMEBOL, which presides over South America, were the two latest arrests in what is proving a miserable year for the organization in charge of running one of the world's most popular sports.
