A football fan has reportedly died in a riot at a league football match in Brazil.
Pictures and video footage of rioting have circulated widely online showing violence on the stands at the game between Atletico PR and Vasco da Gama.
At least three fans were airlifted to hospital after the match was halted and a helicopter landed on the pitch.
The horrifying scenes broke out just 10 minutes into play - and just days after the draw for the 2014 World Cup.
Vasco club director Antonio Peralta, said: "We have one fan in a coma, and a supporter of the other side is dead. Or so I’ve heard.
"This is not a circus, it is recreation, a sporting event that has to bring joy and not death. At Vasco we do not accept that."
Atletico defender Luiz Alberto was visibly shaken by the scenes, seen weeping as he told television crews: "They were trying to escape the Atletico fans. We saw a young lad laying down, getting kicked, being hit by blocks of wood.
"He is a human being. This needs to stop. We asked them to stop, and they did not listen to us."
