Police to probe fan violence in BrazilBrazil hopes to make the space in and around stadiums a safer place for supporters -
Brazil's public prosecutors have launched an investigation into a riot amongst supporters that killed one person and left another injured.
Marcio Barreto de Toledo, 34, died after being attacked by São Paulo fans wielding iron bars following Santos' 0-0 draw in the São Paulo state championship on Sunday.
Another man remained in hospital on Monday with injuries that were not life threatening, according to newspaper Estado de S.Paulo.
Prosecutor Roberto Senise Lisboa has asked military police for reports of the incident.
It is thought that the prosecutor might lay criminal charges against organised fan groups linked to the two clubs.
On Monday Santos condemned the violence.
"The club believes peace is an essential condition for the development of world football. We send our condolences to the families of the fans involved," the club said in a statement.
In December four fans were left hospitalised after violence erupted during a game between Atlético Paranaense and Vasco da Gama.
