BELO HORIZONTE, Brazil (AP) ― Brazilian police detained on Saturday two suspected members of Argentina’s infamous hooligan gangs ― known in Spanish as “Barras Bravas.”

The pair were among nearly 20 Argentines detained inside the Mineirao stadium where Argentina beat Iran 1-0.

All were turned loose by Brazil’s federal police, but the two tagged as being known hooligans were ordered to leave Brazil within 72 hours, and not return during the World Cup.

Meanwhile, policing of a central Belo Horizonte plaza was beefed up after dozens of Argentine and Brazilian fans got into a drunken street clash in the early morning hours Saturday. They launched beer bottles and insults at one another, but no injuries were reported, police said.
