Brazil’s attorney general has filed an indictment against 39 people for their alleged involvement in the storming of the Senate building on 8 January.
The riot saw thousands of supporters of former president Jair Bolsonaro attack government buildings following his election loss last year.
The indictment says the individuals – who are not named – used violence and threats to try to abolish democracy.
Mr Bolsonaro has voiced “regret” for the unrest, but denies he caused it.
Perceived threats to democratic order are a sensitive subject in a country where military rule ended in 1985.
