Police say a 21-year-old man died after a confrontation between rival football fan groups in Brazil on Sunday.
Authorities say the man was run over by a car after he and other Palmeiras fans went onto a major highway to try to ambush two buses carrying Santos supporters to a Brazilian league game in Sao Paulo.
Four fans remained hospitalized, including one with a gunshot wound. Their condition wasn't immediately available.
Police said Palmeiras fans tried to block the buses and used rocks and pieces of wood in the attack against the Santos supporters. Authorities believe one of them shot at the Palmeiras fans.
Four people have been detained.
Police had to partially block the highway that links the coastal city of Santos to Sao Paulo for nearly two hours.
