The former Brazilian leader has been detained after authorities concluded he posed a concrete flight risk while under home confinement.
The ex-president was convicted of orchestrating a government overthrow in the ninth month and given more than 27 years in prison, but he remained under house arrest pending appeals.
Brazilian Supreme Court Justice the presiding justice said the decision to arrest the septuagenarian politician was a precautionary step after recent developments came to light.
This encompassed attempting to break his ankle monitor and a invitation to a supporters' gathering that could facilitate a possible escape.
Legal Document Reveals Escape Risks
In a paperwork permitting the custody, the magistrate said data from the centre monitoring the former president's confinement suggested the ex-president's "intention to break the tracking monitor to guarantee victory in his escape.
This, it said, would be assisted by the disorder caused by the gathering called by his child.
His offspring, Flávio Bolsonaro, who serves as a legislator, called for a meeting of his backers near the former president's residence to take place on Saturday evening.
His son wrote on online platforms on the previous day: "Are you going to fight for your nation, or observe everything from your mobile device there on your settee? I invite you to struggle with us."
He said the demonstration would be so supporters could "pray for his health and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the possibility of his "relocation to diplomatic missions near the residence, considering that the inquiries revealed a record of planning to seek refuge through a consular facility", a statement said.
The legal document underscores that the United States embassy in the capital, Brasilia, is located around 8 miles from the former president's residence.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow right-wing populist US President Trump, causing him to enact a half-rate duty on goods coming from Brazil.
Bolsonaro is being held in a federal law enforcement building in Brazil's capital city 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 Top Court to allow him to serve his whole jail sentence under house arrest, with tracking devices.
They also petitioned that he be permitted to exit his dwelling for healthcare, saying he required regular treatment for pulmonary infections and other ailments.
Background on Conviction
The former president was found guilty of leading a plot aimed at keeping him in power after he failed to win the national vote to his left-wing rival, President Lula.
High Court judges said that he was aware of a scheme which included plans to kill his opponent and his vice-presidential running mate, Alckmin, and to detain and kill Alexandre de Moraes - the top judicial official who has been managing Bolsonaro's trial.
The conspiracy was thwarted because it couldn't obtain the endorsement of the armed forces officials. The current president was inaugurated without problem on 1 January 2023.
But a seven days after, on January 8th, thousands of Bolsonaro supporters stormed and vandalised government buildings in the capital, Brazil's capital.
The police stepped in and around 1,500 people were taken into custody.
The magistrates found that the protesters had been provoked by the former president whose scheme, they said, was for the national armed forces to step in, bring back stability and reinstate his authority.
At the moment, Bolsonaro's lawyers called the decades-long sentence extremely harsh.
He was also banned from seeking elected position until twenty-sixty - eight years later after the conclusion of his imprisonment.
The ex-leader called the court case a political persecution and said it was designed to prevent him running in the 2026 national vote.
