Jorge Delhon threw himself under a train in a Buenos Aires suburb on Tuesday, the newspapers Clarin and La Nacion reported on their websites.
A sports marketing executive, Alejandro Burzaco, testified Tuesday that Delhon and another man, Pablo Paladino, took in millions of dollars in bribes in exchange for rights to broadcast football games, according to the reports.
The reports said that at the time the two men worked for Football for All, a government program under former president Cristina Kirchner that held the rights to football broadcasts in Argentina.
Burzaco, the former chairman of Torneos y Competencias S.A., detailed in US federal court in New York how his company paid millions of dollars in bribes to South American Football Confederation (CONMEBOL) executives for more than a decade to secure television rights to major tournaments.
Burzaco, who pleaded guilty in November 2015 to racketeering, wire fraud and money laundering conspiracies, is one of 42 officials and marketing executives indicted in the FIFA scandal.
Three South Americans are on trial in New York — Jose Maria Marin, ex-head of Brazil’s Football Confederation; former FIFA vice president Juan Angel Napout and Manuel Braga, who led Peru’s soccer federation until 2014.
