Palmeiras fan Gilberto Torres Pereira died in intensive care after being struck on the head with an iron bar by a Corinthians supporter Saturday, police said Thursday, reports Xinhua.
Police said they had requested the arrest of a city councilor, Raimundo Faustino, accused of being involved in the clashes.
Globo news portal quatoed Faustino as saying he was forced to defend himself from attackers but denied using a bar.
The incident occurred near a train station in Sao Paulo when rival fans crossed paths before Palmeiras’ 1-2 defeat to Sao Paulo in Brazil’s Serie A championship.
This is the latest in a series of violent episodes to hit Brazilian football.
In February, three fans were shot outside the Arena das Dunas stadium in the northeastern city of Natal – the second football-related shooting at the venue in less than six months.
And in December dozens were injured after a riot during the Brazilian top-flight match between Atletico Paranaense and Vasco da Gama in the southern city of Joinville
