A car has reportedly rammed the gate of the Brazilian president’s palace in the capital Brasilia as pressure grows on Michel Temer to resign.
Security forces fired shots to stop the driver who was later detained, Brazil’s Globo news site reports.
Mr Temer was not in the Alvorada Palace at the time, reports say.
Brazilian media have shown footage of a gate lying on the ground along with what appear to be a number of spent bullet cartridges.
Earlier, a Supreme Court judge sent a charge of corruption against President Temer to Congress – the next move in a process which could see him removed from office and face trial.
Mr Temer has been indicted for arranging to receive millions of dollars in bribes from a meat-processing company.
He has denied any wrongdoing.
The lower house of Congress is expected to vote in the coming weeks on whether to allow him to be tried.
Mr Temer, one-third of his cabinet, four past presidents, and dozens of politicians are either on trial, facing charges or under investigation in a giant three-year corruption inquiry linked to the state oil company.
