Violence back with bang in Brazil

The Brasileirao season-ending game between Atletico Paranaense and Vasco Da Gama was broadcast across much of the country, with the former hoping to make the Copa Libertadores and the latter desperate to avoid relegation.
However, the match ended up being seen around the world as massive crowd trouble and violence resulted in three serious injuries, with a helicopter having to land on the field to remove one of two unconscious fans to hospital.
