Bolsonaro has been detained after authorities concluded he posed a concrete flight risk while under home confinement.
The one-time leader was found guilty of orchestrating a armed takeover in the ninth month and sentenced more than a 27-year term in jail, but he continued under confinement pending court reviews.
Top Judicial Official Alexandre de Moraes said the action to imprison the septuagenarian politician was a preventative measure after fresh information were revealed.
This included trying to remove his tracking device and a call for a demonstration that could enable a chance to flee".
Legal Document Reveals Flight Fears
In a paperwork permitting the arrest, Justice Moraes said intelligence from the unit overseeing the former president's confinement suggested the one-time head of state's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be "facilitated by the confusion caused by the demonstration called by his offspring.
His child, Flávio, who works as a legislator, called for a assembly of his supporters near the former president's residence to take place on Saturday evening.
His son wrote on digital networks on Friday: Do you plan to struggle for your nation, or observe everything from your phone there on your settee? I invite you to fight with us."
He said the gathering would be so followers could seek divine intervention for his health and for the restoration of democratic rule in our land."
Embassy Asylum Concerns
Part of Justice Moraes's determination was the possibility of Bolsonaro's "relocation to diplomatic missions near the residence, considering that the investigations revealed a record of arranging to seek refuge through a diplomatic representation", a announcement said.
The judicial paperwork highlights that the US embassy in the national capital, Brasilia, is situated around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow populist conservative United States President Trump, causing him to implement a 50% tariff on imports of Brazilian goods.
Bolsonaro is being held in a Federal Police station in Brasilia and will experience a imprisonment assessment on the following day.
Latest Court Petitions
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to permit him to serve his whole jail sentence under home confinement, with tracking devices.
They also requested that Bolsonaro be authorized to leave his home for healthcare, saying he demanded frequent medical attention for lung conditions and other ailments.
Background on Conviction
The former president was found guilty of heading a conspiracy aimed at keeping him in power after he was defeated in the 2022 election to his ideological adversary, President Lula.
Top judicial officials said that he was aware of a scheme which encompassed plans to murder his opponent and his running partner, Geraldo Alckmin, and to detain and kill the presiding judge - the High Court judge who has been overseeing the former president's case.
The plot was prevented because it couldn't obtain the support of the military leaders. His successor was sworn in without problem on 1 January 2023.
But a following week, on January 8th, many his backers invaded and destroyed public facilities in the federal district, Brazil's capital.
The police stepped in and around fifteen hundred individuals were arrested.
The judges found that the rioters had been incited by Bolsonaro whose plan, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the time, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also banned from seeking elected position until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The former president called the court case a targeted investigation" and said it was aimed at blocking him running in the 2026 national vote.
