Demonstrators calling for a military coup occupied Brazil's lower house of Congress on Wednesday, during a day of protests that saw public servants in Rio de Janeiro clash with police during an anti-austerity protest.
By early evening, the protesters in Congress, numbering about 60 in total, had been disbanded and arrested by federal police, roughly three hours after they took over the chamber.
The group busted a glass door to gain access to the lower house and clashed violently with legislative guards. Many of the protesters called for a military coup to overturn Brazil's center-right government.
The protesters blasted what they said was endemic government corruption and at one point paused to sing the national anthem of the South American nation, which was ruled by a military dictatorship from 1964 to 1985.
For the past two years an investigation into a long-running and massive political kickback scheme at state-run oil company Petrobras has transfixed Brazil.
Top executives of construction firms have been jailed, over 60 politicians are under investigation, and former President Luiz Inacio Lula da Silva is facing two separate corruption trials related to the case.
