Boca players were angered by their defeat as a controversial VAR call that went against them when a goal from Marcelo Weigandt was disallowed in the second-leg of their round of 16 tie against Brazilian team Atletico Mineiro.
Videos have emerged online of the violent scenes where players from both side fought in the tunnel after the match ended 3-1.
Chaos began to unfold in the tunnels, where footage shows players throwing the metal fencing as officials tried to break up the fight.
“After a long negotiation, mediated by president Sérgio Coelho, and the Argentinian delegation went to the police station to report an incident for property damage and aggression. No one will be arrested.”
Indy100 has contacted Boca Juniors and CONMEBOL - South America’s football governing body for comment.
