The former Brazilian leader has been detained after authorities concluded he posed a serious risk of fleeing while under domestic detention.
The one-time leader was found guilty of planning a military coup in September and handed more than 27 years in prison, but he remained under home detention pending appeals.
Top Judicial Official Alexandre de Moraes said the action to imprison the elderly politician was a safety action after fresh information emerged.
This encompassed attempting to break his ankle monitor and a call for a supporters' gathering that could enable a possible escape.
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the judge said data from the centre monitoring his home detention 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 "facilitated by the disorder caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who works as a senator, called for a gathering of his followers near his father's house to take place on Saturday night.
His son wrote on online platforms on the previous day: Do you plan to struggle for your nation, or watch it all from your phone there on your settee? I call on you to struggle with us."
He said the vigil would be so followers could seek divine intervention for his well-being and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of the judge's decision was the chance of his "relocation to diplomatic missions near the dwelling, considering that the investigations revealed a background of arranging to ask for protection through a embassy office", a announcement said.
The legal document highlights that the American diplomatic mission in the federal district, Brazil's capital, is located around 13km from the former president's residence.
Worldwide Consequences
The former president's legal troubles have provoked anger from fellow populist conservative American leader Donald Trump, causing him to implement a half-rate duty on Brazilian product imports.
He is being detained in a federal law enforcement building in the capital and will have a detention review on Sunday.
Latest Court Petitions
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to allow him to serve his whole jail sentence under home confinement, with tracking devices.
They also requested that he be authorized to exit his dwelling for medical care, saying he required ongoing care for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a scheme aimed at retaining his authority after he was defeated in the 2022 election to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plot which involved plans to kill his opponent and his running partner, his vice-presidential candidate, and to detain and kill Justice Moraes - the High Court judge who has been overseeing his judicial proceedings.
The scheme was prevented because it failed to get the support of the armed forces officials. His successor was sworn in without incident on the first day of 2023.
But a following week, on January 8th, thousands of his followers invaded and destroyed government buildings in the capital, Brasília.
The police took action and around fifteen hundred individuals were arrested.
The justices found that the protesters had been provoked by him whose plan, they said, was for the Brazilian military to take action, restore order and reinstate his authority.
At the period, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The ex-leader called the legal proceedings a targeted investigation" and said it was intended to stop him competing in the 2026 national vote.
