Bolsonaro has been detained after authorities determined he posed a serious risk of fleeing while under house arrest.
The former head of state was found guilty of orchestrating a military coup in last fall and sentenced more than over two decades in incarceration, but he continued under home detention pending appeals.
High Court Judge Alexandre de Moraes said the move to detain the 70-year-old politician was a precautionary step after recent developments were revealed.
This encompassed trying to remove his ankle monitor and a invitation to a demonstration that could enable a potential flight.
Judicial Records Show Flight Fears
In a filing authorising the detention, the magistrate said information from the unit overseeing the former president's confinement suggested the one-time head of state's "intention to break the surveillance device to guarantee victory in his escape.
This, it said, would be "facilitated by the confusion caused by the demonstration called by his son.
His offspring, Flávio, who holds office as a legislator, called for a meeting of his backers near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on Friday: Will you battle for your nation, or see it all from your phone there on your sofa? I invite you to battle with us."
He said the gathering would be so followers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the chance of the former president's transfer to diplomatic missions near the dwelling, considering that the investigations revealed a history of organizing to request asylum through a embassy office", a declaration said.
The legal document highlights that the American diplomatic mission in the federal district, Brazil's capital, is located around approximately 13 kilometers from his dwelling.
Worldwide Consequences
His judicial problems have generated frustration from fellow right-wing populist American leader Trump, causing him to impose a fifty percent tax on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the High Court to allow him to complete his entire prison term under domestic detention, with electronic monitoring.
They also petitioned that Bolsonaro be authorized to exit his dwelling for medical treatment, saying he needed ongoing care for lung conditions and other health problems.
Context of Sentencing
He was found guilty of leading a scheme aimed at keeping him in power after he lost the presidential race to his political opponent, President Lula.
High Court judges said that he knew of a scheme which encompassed plans to assassinate the current president and his VP candidate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The plot was stopped because it couldn't obtain the support of the army and air force commanders. Lula was took office without incident on January 1st, 2023.
But a following week, on 8 January, many his backers attacked and damaged public facilities in the national capital, Brazil's capital.
The police intervened and around fifteen hundred individuals were taken into custody.
The judges found that the protesters had been incited by Bolsonaro whose strategy, they said, was for the Brazilian military to step in, restore order and return him to office.
At the moment, the legal team called the over 27-year sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - eight years after the end of his sentence.
The ex-leader called the legal proceedings a political persecution and said it was intended to stop him running in the 2026 national vote.
