SAO PAULO (AP) -- Authorities say three fans were injured in a shooting after a soccer game at a World Cup stadium.
The fans' injuries were not life-threatening.
Police officer Francisco Araujo Silva told the sports daily Lance that the shots were fired by two men riding a motorcycle as local America supporters left the Arena das Dunas in the northeastern city of Natal on Saturday.
It wasn't the first incident involving fans in Natal this year. Before the stadium's inauguration in January, police arrested two men who shot at a group of rival fans just a few miles away.
Fan violence has been common in Brazil as it finalizes its World Cup preparations.
Just a week ago, Corinthians fans invaded the team's training center and threatened players.
