Shocking hooligan violence during Argentina's finals season is sending shockwaves through the country's sports and political worlds, just days before the G20 leaders summit in Buenos Aires.
Rock-wielding hooligans from the River squad were released from preventative arrest on Sunday, as the CONMEBOL regional governing body suspended the Superclásico final against Boca.
"If the match is handed to Boca, it would be an absolute embarrassment and one of the biggest acts of treachery you could imagine", River Plate club president Rodolfo D'Onofrio told the Debo Decir television programme on Sunday.
His comments come after Boca president Daniel Angelici called for his club to take the cup by default.
He denied the area around River's Monumental stadium had been purposefully abandoned by police.
"We have initiated an internal investigation of the entire operation to see where there were problems and failures, which are very clear (and to analyse) where there were mistakes and to identify those responsible for what happened", he added.
"In the City, the responsibility for security is on our government with our security forces, with the support of federal forces", he clarified.
