2 Argentine fans being investigated for allegedly yelling racist slurs during World Cup match

Two Argentine soccer fans are being investigated by Rio de Janeiro police for allegedly shouting racist slurs at Brazilians who were rooting for Bosnia-Herzegovina in its World Cup match against Argentina.

A police statement confirms the incident happened Sunday inside Maracana stadium but declines to disclose the identities of the two Argentines. It says they were released after being questioned.

The newspaper O Estado de S.Paulo says the incident involved two people who shouted "little monkeys" at a group of Brazilians who were cheering for Bosnia after its second-half goal.

Brazilian organizers are using the World Cup to draw attention to the country's racial diversity and President Dilma Rousseff has called on foreign visitors to help promote a tournament free of racism and prejudice.
