The former Brazilian leader has been taken into custody after authorities found he posed a serious risk of fleeing while under domestic detention.
The ex-president was sentenced of plotting a armed takeover in last fall and handed more than 27 years in prison, but he remained under house arrest pending legal challenges.
Brazilian Supreme Court Justice Alexandre de Moraes said the decision to arrest the septuagenarian politician was a preventative measure after fresh information emerged.
This included attempting to break his ankle monitor and a invitation to a supporters' gathering that could "allow for a potential flight.
Legal Document Reveals Escape Concerns
In a document approving the detention, the magistrate said data from the unit overseeing the former president's confinement suggested the ex-president's "intention to break the surveillance device to secure accomplishment in his flight.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his offspring.
His child, Flávio, who serves as a congressional representative, called for a assembly of his followers near his father's house to take place on Saturday night.
His son wrote on online platforms on last Friday: "Are you going to fight for your country, or watch it all from your mobile device there on your sofa? I urge you to battle with us."
He said the gathering would be so backers could offer prayers for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of the magistrate's decision was the possibility of Bolsonaro's move to diplomatic missions near the home, considering that the investigations revealed a record of organizing to request asylum through a consular facility", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the federal district, Brazil's capital, is situated around 13km from his dwelling.
International Reactions
The former president's legal troubles have drawn the ire of fellow right-wing populist US President Donald Trump, causing him to impose a half-rate duty on imports of Brazilian goods.
Bolsonaro is being kept in a federal law enforcement building in Brasilia and will have a imprisonment assessment on the following day.
Recent Judicial Appeals
It was only on Friday that the ex-leader's attorneys asked the High Court to allow him to complete his entire prison term under house arrest, with electronic monitoring.
They also petitioned that Bolsonaro be authorized to leave his home for medical treatment, saying he demanded frequent medical attention for lung conditions and other illnesses.
Background on Conviction
Bolsonaro was determined responsible of orchestrating a conspiracy aimed at retaining his authority after he lost the national vote to his ideological adversary, Lula.
Supreme Court justices said that he knew of a plan which involved plans to assassinate Lula and his VP candidate, Geraldo Alckmin, and to imprison and murder Justice Moraes - the Supreme Court justice who has been overseeing his judicial proceedings.
The scheme was prevented because it couldn't obtain the backing of the military leaders. His successor was sworn in without problem on the first day of 2023.
But a week later, on the eighth of January, numerous his backers stormed and vandalised public facilities in the federal district, Brasília.
The law enforcement intervened and around fifteen hundred individuals were taken into custody.
The magistrates found that the rioters had been incited by him whose plan, they said, was for the country's army to step in, restore order and reinstate his authority.
At the moment, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - eight years after the completion of his term.
The ex-leader called the legal proceedings a targeted investigation" and said it was intended to stop him running in the 2026 presidential election.
