Police have fired tear gas at indigenous protesters during an anti-World Cup demonstration in Brazil’s capital, Brasilia.
Over 1,000 people attempted to march on the Mane Garrincha National Stadium on Tuesday.
Demonstrators were rallying against Brazil hosting the World Cup and the vast amount of money spent on the tournament instead of improving the country’s public services.
A group of indigenous people, protesting against legislation before the Brazilian Congress threatening to change reservation boundaries, also joined the protest.
Some were armed with bows and arrows and fired at the police.
One officer was shot in the leg and required surgery to remove the arrow.
A police spokesman said officers had tried to contain the march using tear gas.
Mounted police also attempted to control the large protest, which shutdown one of the main roads in Brasilia.
The protest was broadcast live on TV and showed some of the protesters picking up the gas canisters and hurling them back at the police.
Later, activists claimed at least two indigenous people had been injured in the clashes, but there was no information on their condition.
The protest eventually resulted in a ceremony to open an exhibition of the World Cup trophy being cancelled.
Earlier, another group of indigenous people climbed onto the roof of Congress to demand a change in the way boundaries around indigenous land are drawn up.
"Scaling the Congress building was an act of bravery, it shows we're warriors who defend our rights," indigenous leader Tamalui Kuikuru told AFP.
The Mane Garrincha National Stadium is set to host a number of games in the 2014 World Cup.
Tuesday’s clashes in Brasilia followed a peaceful march on Sao Paulo last week.
Brazil has witnessed regular demonstrations in the lead up to 2014 World Cup, which begins on June 12.
