Court Filing Details Escape Risks
In a paperwork permitting the custody, the judge said information from the facility tracking the former president's confinement suggested the one-time head of state's aim to disable the surveillance device to guarantee victory in his escape.

Flávio Bolsonaro wrote on social media on Friday: Do you plan to struggle for your homeland, or watch it all from your phone there on your sofa? I call on you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his well-being and for the restoration of democratic rule in our land."
Foreign Shelter Risks

Background on Conviction
The former president was determined responsible of heading a scheme aimed at retaining his authority after he was defeated in the 2022 election to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a scheme which encompassed plans to assassinate Lula and his VP candidate, his vice-presidential candidate, and to arrest and execute Justice Moraes - the High Court judge who has been managing his judicial proceedings.
The conspiracy was prevented because it failed to get the endorsement of the army and air force commanders. His successor was took office without issue on 1 January 2023.
But a seven days after, on January 8th, thousands of Bolsonaro supporters attacked and damaged official structures in the national capital, Brasília.
The police intervened and around 1,500 people were detained.
The justices found that the rioters had been incited by Bolsonaro whose scheme, they said, was for the Brazilian military to intervene, bring back stability and return him to office.
At the period, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The one-time head of state called the trial a political persecution and said it was designed to prevent him running in the 2026 national vote.
