After Coritiba scored a last-minute winner against Cruzeiro, fans invaded the field, leading to a riot involving over a hundred people in Brazil.
Coritiba had been behind 1-0 until Robson Fernandes struck a spectacular equalizer in the 91st minute.
Hundreds of fans from the home team stormed the field to celebrate with the players after their victory.
The joy, however, did not last long, as Cruzeiro fans followed suit and stormed the field.
During the match, fans from both teams got into a massive brawl in the middle of the field.
The fight swiftly got out of hand, and the security team was helpless to stop it.
The brawl went on for a while until the police were able to break it up.
There were several people who suffered injuries, including two police officers.
Brazil's soccer governing body, the CBF, has launched an investigation into the violence and issued a strong condemnation.
Coritiba and Cruzeiro have both issued statements condemning the violence and apologizing to their respective fan bases.
Coritiba released a statement in which they criticized the pitch invasion.
'The Coritiba Football Club comes out to vehemently repudiate the field invasion initiated by the fans of Cruzeiro, right after Coritiba's goal, which gave rise to widespread turmoil.
'Situations like this are unacceptable and only harm clubs and Brazilian football.
'The club is working to identify the invaders and those responsible for the incident.'
The incident is a reminder of the serious problem of football hooliganism and violence in Brazil.
The CBF has taken steps to reduce violence in recent years, but more needs to be done to address the problem.
