Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under house arrest.
The one-time leader was found guilty of plotting a armed takeover in last fall and handed more than a 27-year term in incarceration, but he remained under confinement pending appeals.
Top Judicial Official Justice Moraes said the move to detain the 70-year-old politician was a precautionary step after recent developments were revealed.
This encompassed attempting to break his ankle monitor and a invitation to a demonstration that could "allow for a chance to flee".
Court Filing Details Escape Concerns
In a document approving the arrest, the judge said information from the unit overseeing Bolsonaro's house arrest suggested the ex-president's plan to remove the surveillance device to guarantee victory in his getaway".
This, it said, would be made easier by the confusion caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who holds office as a senator, called for a assembly of his supporters near his father's house to take place on the weekend.
The senator wrote on digital networks on Friday: "Are you going to fight for your nation, or watch it all from your phone there on your sofa? I urge you to struggle with us."
He said the gathering would be so backers could seek divine intervention for his well-being and for the reestablishment of democratic governance in our country."
Diplomatic Refuge Fears
Part of the judge's ruling was the possibility of the former president's transfer to foreign missions near the home, considering that the investigations revealed a history of organizing to seek refuge through a diplomatic representation", a statement said.
The judicial paperwork highlights that the United States embassy in the federal district, the capital city, is situated around 8 miles from the former president's residence.
International Reactions
His judicial problems have provoked anger from fellow populist conservative US President Trump, prompting him to impose a 50% tariff on imports of Brazilian goods.
The former president is being kept in a federal law enforcement building in Brazil's capital city and will have a imprisonment assessment on the following day.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to authorize him to fulfill his full incarceration period under home confinement, with electronic monitoring.
They also requested that the former president be permitted to leave his home for healthcare, saying he needed ongoing care for pulmonary infections and other illnesses.
Details of Guilty Verdict
He was found guilty of leading a scheme aimed at retaining his authority after he was defeated in the 2022 election to his left-wing rival, Lula.
High Court judges said that he had knowledge of a plan which encompassed plans to assassinate Lula and his vice-presidential running mate, his vice-presidential candidate, and to detain and kill the presiding judge - the High Court judge who has been managing the former president's case.
The conspiracy was prevented because it failed to get the backing of the army and air force commanders. His successor was took office without problem on 1 January 2023.
But a week later, on the eighth of January, thousands of Bolsonaro supporters stormed and vandalised official structures in the national capital, Brazil's capital.
The police intervened and around approximately 1,500 persons were detained.
The judges found that the protesters had been provoked by Bolsonaro whose plan, they said, was for the national armed forces to step in, reestablish control and bring him back to power.
At the moment, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also barred from running for public office until 2060 - eight years after the completion of his term.
The ex-leader called the legal proceedings a "witch hunt and said it was intended to stop him participating in the 2026 presidential election.
