This happened during  a boxing  card at Club Once Unidos in Mar del Plata, Buenos Aires, Argentina  on Friday night.

Some fans didn't really like the decision, so they rioted after a fight where Filipino Johnriel Casimero beat Argentine Luis Alberto Lazare by TKO to win the IBF light flyweight title.

The fans their objections by throwing chairs and other objects into the ring. Some of the people even went after Casimero.
