Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of plotting a military coup in the ninth month and sentenced more than over two decades in prison, but he remained under confinement pending legal challenges.
Top Judicial Official Justice Moraes said the action to imprison the septuagenarian politician was a safety action after fresh information emerged.
This encompassed seeking to disable his electronic bracelet and a invitation to a supporters' gathering that could enable a potential flight.
Legal Document Reveals Flight Fears
In a document approving the detention, Justice Moraes said intelligence from the centre monitoring the former president's confinement suggested the one-time head of state's "intention to break the surveillance device to ensure success in his escape.
This, it said, would be made easier by the chaos caused by the gathering called by his son.
His son, Flávio, who serves as a congressional representative, called for a assembly of his backers near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your homeland, or observe everything from your phone there on your settee? I urge you to struggle with us."
He said the demonstration would be so backers could seek divine intervention for his well-being and for the reestablishment of democratic governance in our country."
Embassy Asylum Concerns
Part of the magistrate's determination was the chance of Bolsonaro's "relocation to embassies near the dwelling, considering that the inquiries revealed a background of organizing to ask for protection through a diplomatic representation", a statement said.
The court filing underscores that the American diplomatic mission in the capital, Brasilia, is situated around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow right-wing populist US President Donald Trump, prompting him to implement a 50% tariff on imports of Brazilian goods.
He is being held in a national police facility in the capital and will experience a imprisonment assessment on the next day.
Latest Court Petitions
It was only on the previous day that the former president's lawyers asked the Supreme Court to permit him to serve his whole jail sentence under house arrest, with digital surveillance.
They also petitioned that the former president be authorized to depart his residence for healthcare, saying he demanded regular treatment for lung conditions and other health problems.
Context of Sentencing
Bolsonaro was found guilty of heading a scheme aimed at keeping him in power after he was defeated in the 2022 election to his left-wing rival, Lula.
Supreme Court justices said that he had knowledge of a scheme which involved plans to kill Lula and his vice-presidential running mate, Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been managing the former president's case.
The scheme was prevented because it couldn't obtain the support of the armed forces officials. His successor was inaugurated without incident on January 1st, 2023.
But a following week, on January 8th, thousands of his followers stormed and vandalised official structures in the capital, Brazil's capital.
The law enforcement stepped in and around approximately 1,500 persons were taken into custody.
The judges found that the demonstrators had been provoked by Bolsonaro whose scheme, they said, was for the Brazilian military to take action, restore order and return him to office.
At the time, his attorneys called the decades-long sentence "absurdly excessive.
He was also barred from seeking elected position until twenty-sixty - a decade minus two years after the end of his sentence.
The one-time head of state called the court case a targeted investigation" and said it was designed to prevent him running in the 2026 presidential election.
