Medellin witnessed massive violence on Wednesday night after frantic fans of the rival teams were engaged in hostility, destroying stadium infrastructure and clashing with each other, including the police officers.

Medellin Mayor Federico Gutierrez said there would be consequences for those who attended Wednesday’s Copa Colombia final to “generate violence” after 59 people were injured, including seven police officers, in clashes between rival fans.

Violence broke out after Atlético Nacional defeated Medellín rival Deportivo Independiente Medellín 1-0 in the second leg of the Copa Colombia final at Estadio Atanasio Girardot.

William Castano told news channel Teleantioquia that officers had seized weapons, flares, and fireworks from fans during checks at the stadium.

“It was necessary to apply the graduated use of force, to help prevent the occupation of the pitch by the fans, to control outbreaks of public order disturbances, and to guarantee the safety of citizens attending the event,” Castano added.

Mayor Gutierrez said on social media that the majority of fans at the stadium were there to watch football, but a group of “misfits” was intent on violence.

“Anyone who went to the stadium to attack, destroy, or incite fear will be held accountable under the law. We will not allow a few to damage what belongs to everyone,” he wrote.

“For years, we’ve been a beacon of peaceful football in our country and throughout Latin America. What a disappointment.”
