Fans shot dead near Brazil stadium
Two fans were killed in a shooting on Sunday when they were on their way to a game at 2014 World Cup stadium Castelao.
The match, between Ceara and Fortaleza, was a test event for the Confederations Cup this summer.
The Ceara supporters were shot in the head after a confrontation with Fortaleza fans about five kilometres from the stadium, with witnesses telling police the victims were on their way to the stadium when rival fans on a motorcycle opened fire.
"We lament what happened. But there is work being done by the police and the army in many areas of security, so we are not concerned with that for the Confederations Cup," World Cup organising committee member Tiago Paes said.
Authorities later detained a man on a motorcycle near the crime scene who allegedly carried a gun, but details about the suspect's identity have not yet been released.
Furthermore, more than 180 people were arrested for vandalism and disorderly conduct before Sunday's match.
The Castelao is one of the six stadiums hosting games for the Confederations Cup and one of 12 venues for next year's World Cup.
