SANTO DOMINGO, Dominican Republic -- Authorities in the Dominican Republic have arrested former MLB pitcher Octavio Dotel and and cited ex-infielder Luis Castillo for their alleged links to a drug-trafficking and money-laundering ring, officials said Tuesday.

Dominican Attorney General Jean Alain Rodriguez said police are also actively pursuing the alleged leader of the ring, Cesar Emilio Peralta, also known as "Cesar the Abuser.'' Castillo -- not the current Cincinnati Reds' pitcher -- has not yet been arrested.

"Eighteen other people are linked to this network, including athletes and baseball players Octavio Dotel and Luis Castillo,'' Rodriguez said in a news conference, calling it "the most important drug-trafficking structure in the region.''

He said Peralta created a complicated system of companies to hide the origins of his assets, using members of his family and social circles, "including two sports figures in the Dominican Republic.''

Rodriguez said the U.S. government and police agencies participated in the investigation.

Dominican officials say a 1,050-kilogram shipment of drugs heading from South America to Puerto Rico was one of several seizures attributed to this ring.

Alan Wilmot, a member of Castillo's legal team, denied any connection of Castillo to the alleged wrongdoing. "Mr. Castillo maintains his innocence," Wilmot said.

Castillo was a three-time All-Star, won three Gold Gloves and was a member of the 2003 Florida Marlins team that won the World Series.

There was no immediate comment from Dotel, who set a record at the time for playing on more MLB teams than any other player. The teams were: the Detroit Tigers, St. Louis Cardinals, Toronto Blue Jays, Colorado Rockies, Los Angeles Dodgers, Pittsburgh Pirates, Chicago White Sox, Atlanta Braves, Kansas City Royals, New York Yankees, Oakland Athletics, Houston Astros and New York Mets.
