MIAMI -- Three South Florida men were among more than two dozen arrested Wednesday in an international sweep targeting the Italian mafia, according to the FBI.

The FBI and Italian national police officers arrested 41-year old Roberto Settineri at his Miami Beach home on an indictment that includes money laundering and obstruction of justice.

Enrique Ros and Daniel Drumenhause, two accused helpers, were named in the indictment. Drumenhauser was arrested; Ros is still at large.

"Destroying documents important to a grand jury investigation and agreeing to launder money they knew came from proceeds of a mail and wire fraud case," said Jeffrey Sloman, United States Attorney for Florida's Southern District, describing the extent of the allegations.

Sloman held a news conference at his Miami office in conjunction with Italian authorities, who revealed details of the coordinated sweep in Palermo, Italy. It was there that 20 alleged members of the Cosa Nostra were taken into custody.

Settineri is accused of being the United States conduit for the Santa Maria di Gesu crime family in Palermo, laundering money and obstructing a federal investigation. He was also among those charged in Palermo for crimes that included extortion, drug trafficking and attempted murder.

"All mafia crimes -- that's why it was so dangerous," said Raffaele Grassi, who spoke at the news conference on behalf of the Italian National Police. "The mafia in Sicily could live through the work Sentinerri was doing."

"In a separate indictments, Miami resident Antonio Tricamo was arrested and charged with laundering money for the family's counterfeit cigarettes business. In New York, FBI agents arrested a father and two sons alleged to be associated with the Gambino crime family. All are said to be associates of Settineri, who is in federal custody in Broward County.

Though he faces charges in the United States and in Italy, he will first be tried in the U.S.
