SAO PAULO (AP) -- Brazilian authorities say they have detained 19 people for their alleged involvement in fan violence that marked the final round of the Brazilian league this month.
Police in three states had arrest warrants for nearly 30 people in a joint operation being called ''Red Card,'' with detentions made throughout the day on Thursday.
Authorities used television images to identify the fans. Among those arrested was a former council member in the southern city of Curitiba and one of the four men hospitalized after the brawl.
Three men had been arrested the day of the Dec. 8 fight, which resulted in police firing rubber bullets during the Atletico Paranaense game against Vasco da Gama. One of the injured men was airlifted from the field to a hospital.
