Interpol, the intergovernmental organization whose primary role is to assist law-enforcement agencies around the world, has issued “red notices” for six people tied to the FIFA corruption scandal. The move came less than one day after FIFA President Sepp Blatter stunned the sports world by announcing his impending retirement.

In essence, the red notices serve to alert Interpol’s 190 member nations that arrest warrants have been issued by the United States for two former FIFA executives and four South American businessmen accused of bribery. The notices are not arrest warrants themselves, as Interpol does not have the authority to arrest anyone and cannot compel a nation to arrest anone. The notices simply request that member countries arrest the individuals with the goal of extraditing them to the nation that charged them with crimes.

The red notices where issued at the request of the United States, which has indicted 18 people in connection with corruption within FIFA, world soccer’s governing body. All six have been indicted already by the United States. They are:

Jack Warner: Former FIFA vice president and president of CONCACAF, the governing body of soccer in North America, Central America and the Caribbean. Warner already has been arrested and released after posting bail in his native Trinidad. Authorities there have taken away his passport.

Nicolas Leoz: Paraguayan former member of FIFA’s executive committee and former president of South America’s governing soccer body. Leoz, 86, has been placed under house arrest in his home country.

Alejandro Burzaco: CEO of Torneos y Competencias, an Argentine marketing company. Accused of paying hundreds of millions of dollars in bribes. A judge in Argentina has ordered his arrest, and he’s considered a fugitive.

Hugo and Mariano Jinkis: Argentine father and son. Hugo Jinkis is owner and CEO of Full Play Group, a company in Argentina that holds the broadcasting rights to many soccer teams in South and Central America. Accused along with Burzaco of paying bribes to secure the broadcast rights to soccer tournaments.

Jose Margulies: Argentine-born broadcast executive who has spent most of his life in Brazil. He is suspected of negotiating the illegal payments for broadcasting rights. According to one report from South America, Margulies is on vacation in Europe and plans to attend Saturday’s Champions League final in Berlin.
