Jair Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of planning a military coup in the ninth month and sentenced more than over two decades in jail, but he remained under confinement pending court reviews.
Top Judicial Official the presiding justice said the decision to arrest the elderly politician was a preventative measure after fresh information emerged.
This included seeking to disable his ankle monitor and a invitation to a public vigil that could facilitate a possible escape.
Judicial Records Show Escape Concerns
In a paperwork permitting the custody, the judge said intelligence from the centre monitoring his home detention suggested the ex-president's aim to disable the surveillance device to ensure success in his escape.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his son.
His son, Flávio, who serves as a congressional representative, called for a assembly of his backers near Bolsonaro's home to take place on Saturday night.
The senator wrote on social media on Friday: Do you plan to struggle for your country, or watch it all from your smartphone there on your sofa? I urge you to battle with us."
He said the demonstration would be so followers could offer prayers for his health and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of the judge's determination was the potential of the former president's "relocation to diplomatic missions near the home, considering that the probes revealed a record of arranging to ask for protection through a embassy office", a declaration said.
The judicial paperwork emphasizes that the US embassy in the capital, Brasilia, is situated around 13km from his dwelling.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow populist conservative US President President Trump, causing him to enact a half-rate duty on goods coming from Brazil.
The former president is being detained in a national police facility in the capital and will have a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on the previous day that the former president's lawyers asked the High Court to authorize him to fulfill his full incarceration period under home confinement, with electronic monitoring.
They also petitioned that Bolsonaro be authorized to exit his dwelling for medical care, saying he needed regular treatment for pulmonary infections and other illnesses.
Details of Guilty Verdict
The former president was determined responsible of orchestrating a plot aimed at retaining his authority after he lost the national vote to his ideological adversary, President Lula.
High Court judges said that he was aware of a scheme which encompassed plans to assassinate his opponent and his running partner, Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been presiding over his judicial proceedings.
The conspiracy was thwarted because it couldn't obtain the endorsement of the military leaders. The current president was sworn in without incident on 1 January 2023.
But a following week, on 8 January, many Bolsonaro supporters stormed and vandalised official structures in the capital, Brazil's capital.
The security forces took action and around fifteen hundred individuals were detained.
The justices found that the rioters had been provoked by him whose plan, they said, was for the Brazilian military to intervene, reestablish control and bring him back to power.
At the moment, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also banned from running for public office until the year 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the trial a political persecution and said it was intended to stop him running in the 2026 national vote.
