The former Brazilian leader has been arrested after authorities determined he posed a concrete flight risk while under domestic detention.
The one-time leader was sentenced of plotting a government overthrow in last fall and handed more than a 27-year term in incarceration, but he was staying under house arrest pending legal challenges.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the 70-year-old politician was a precautionary step after recent developments emerged.
This included attempting to break his tracking device and a summons to a public vigil that could enable a chance to flee".
Judicial Records Show Flight Fears
In a document approving the detention, the magistrate said data from the unit overseeing the former president's confinement suggested the one-time head of state's plan to remove the surveillance device to secure accomplishment in his escape.
This, it said, would be assisted by the confusion caused by the demonstration called by his offspring.
His child, Flávio, who works as a congressional representative, called for a meeting of his backers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on online platforms on Friday: "Are you going to fight for your homeland, or see it all from your mobile device there on your sofa? I invite you to fight with us."
He said the demonstration would be so backers could seek divine intervention for his well-being and for the restoration of democratic rule in our country."
Embassy Asylum Concerns
Part of the magistrate's determination was the possibility of his "relocation to embassies near the residence, considering that the inquiries revealed a background of planning to seek refuge through a consular facility", a declaration said.
The court filing highlights that the United States embassy in the national capital, Brasilia, is positioned around 13km from his dwelling.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow right-wing populist US President President Trump, prompting him to enact a half-rate duty on imports of Brazilian goods.
He is being detained in a national police facility in Brasilia and will experience a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the Supreme Court to authorize him to serve his whole jail sentence under house arrest, with digital surveillance.
They also asked that Bolsonaro be allowed to leave his home for medical care, saying he required ongoing care for pulmonary infections and other illnesses.
Details of Guilty Verdict
The former president was convicted of orchestrating a scheme aimed at keeping him in power after he lost the 2022 election to his political opponent, Lula.
High Court judges said that he had knowledge of a plot which encompassed plans to kill the current president and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was prevented because it didn't receive the endorsement of the army and air force commanders. The current president was inaugurated without problem on 1 January 2023.
But a following week, on 8 January, numerous his followers attacked and damaged public facilities in the national capital, Brasília.
The police took action and around 1,500 people were detained.
The magistrates found that the rioters had been incited by the former president whose strategy, they said, was for the country's army to intervene, restore order and return him to office.
At the moment, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also barred from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The ex-leader called the court case a "witch hunt and said it was intended to stop him running in the 2026 presidential election.
