Bolsonaro has been detained after authorities concluded he posed a serious risk of fleeing while under domestic detention.
The ex-president was sentenced of orchestrating a military coup in the ninth month and sentenced more than a 27-year term in incarceration, but he remained under home detention pending court reviews.
High Court Judge Justice Moraes said the decision to arrest the elderly politician was a precautionary step after "new facts" came to light.
This included trying to remove his electronic bracelet and a invitation to a public vigil that could facilitate a possible escape.
Judicial Records Show Flight Fears
In a paperwork permitting the detention, the magistrate said intelligence from the centre monitoring the former president's confinement suggested the one-time head of state's "intention to break the electronic ankle bracelet to ensure success in his escape.
This, it said, would be made easier by the confusion caused by the protest called by his child.
His offspring, his son Flávio, who holds office as a senator, called for a assembly of his backers near Bolsonaro's home to take place on Saturday night.
The senator wrote on online platforms on last Friday: Do you plan to struggle for your country, or watch it all from your smartphone there on your couch? I urge you to struggle with us."
He said the vigil would be so backers could "pray for his health and for the return of democracy in our country."
Foreign Shelter Risks
Part of Justice Moraes's determination was the chance of the former president's move to foreign missions near the residence, considering that the inquiries revealed a background of organizing to ask for protection through a consular facility", a declaration said.
The legal document underscores that the American diplomatic mission in the capital, Brasilia, is positioned around approximately 13 kilometers from the former president's residence.
Global Responses
His judicial problems have provoked anger from fellow right-wing populist United States President Trump, prompting him to enact a 50% tariff on imports of Brazilian goods.
He is being detained in a Federal Police station in Brazil's capital city and will experience a detention review on the next day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the Top Court to authorize him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that Bolsonaro be permitted to exit his dwelling for healthcare, saying he required ongoing care for respiratory ailments and other health problems.
Details of Guilty Verdict
He was convicted of leading a conspiracy aimed at maintaining his control after he lost the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a scheme which involved plans to murder the current president and his VP candidate, Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was thwarted because it didn't receive the endorsement of the military leaders. Lula was took office without incident on 1 January 2023.
But a week later, on the eighth of January, many his followers attacked and damaged official structures in the capital, the capital city.
The law enforcement intervened and around approximately 1,500 persons were detained.
The justices found that the demonstrators had been incited by Bolsonaro whose plan, they said, was for the national armed forces to take action, restore order and reinstate his authority.
At the time, the legal team called the over 27-year sentence unreasonably severe".
He was also prohibited from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the trial a targeted investigation" and said it was aimed at blocking him competing in the next presidential race.
