An Argentine fan in Brazil for the World Cup was shot in the leg during a bar fight, security officials said on Wednesday.

The Argentine fan shot in the leg escaped serious injury and he was treated at an emergency room during Wednesday’s pre-dawn hours, according to a public security spokesman.

Six other Argentine fans were arrested for trying to steal tickets to their national team’s match against Nigeria on Wednesday in Porto Alegre.

Tens of thousands of Argentines came to Brazil this month, prompting increased security measures focused on Argentina’s notorious hooligans. Brazil has already stopped more than 30 Argentines from entering the country due to their involvement with the violent “barras bravas” fan clubs in their national league.

Both Argentina and Brazil finished at the top of their respective groups in the first round of the tournament, so their only possible face off would be in the World Cup final on July 13 at the storied Maracana Stadium in Rio de Janeiro.
