Bolsonaro has been arrested after authorities found he posed a definite escape threat while under domestic detention.
The former head of state was sentenced of plotting a government overthrow in September and sentenced more than 27 years in jail, but he continued under house arrest pending legal challenges.
High Court Judge Alexandre de Moraes said the decision to arrest the 70-year-old politician was a precautionary step after recent developments emerged.
This encompassed trying to remove his electronic bracelet and a summons to a supporters' gathering that could enable a chance to flee".
Court Filing Details Flight Fears
In a paperwork permitting the custody, Justice Moraes said intelligence from the centre monitoring Bolsonaro's house arrest suggested the former leader's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the protest called by his child.
His son, his son Flávio, who holds office as a congressional representative, called for a assembly of his followers near Bolsonaro's home to take place on Saturday evening.
The senator wrote on social media on Friday: Do you plan to struggle for your country, or observe everything from your mobile device there on your settee? I call on you to battle with us."
He said the vigil would be so followers could "pray for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the possibility of Bolsonaro's move to foreign missions near the residence, considering that the probes revealed a record of organizing to request asylum through a consular facility", a statement said.
The court filing highlights that the American diplomatic mission in the federal district, the capital city, is situated around approximately 13 kilometers from Bolsonaro's home.
International Reactions
His judicial problems have provoked anger from fellow right-wing populist United States President Donald Trump, leading him to enact a fifty percent tax on Brazilian product imports.
He is being detained in a Federal Police station in the capital and will undergo a imprisonment assessment on the next day.
Recent Legal Requests
It was only on Friday that the former president's lawyers asked the Supreme Court to allow him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also asked that the former president be allowed to depart his residence for medical treatment, saying he needed ongoing care for respiratory ailments and other illnesses.
Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a scheme aimed at maintaining his control after he failed to win the national vote to his ideological adversary, President Lula.
Supreme Court justices said that he had knowledge of a plot which included plans to assassinate his opponent and his VP candidate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been overseeing Bolsonaro's trial.
The conspiracy was stopped because it failed to get the endorsement of the army and air force commanders. Lula was took office without problem on the first day of 2023.
But a seven days after, on January 8th, many his followers invaded and destroyed official structures in the federal district, the capital city.
The law enforcement stepped in and around fifteen hundred individuals were taken into custody.
The magistrates found that the protesters had been incited by him whose strategy, they said, was for the country's army to step in, reestablish control and return him to office.
At the period, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until twenty-sixty - eight years after the completion of his term.
The former president called the trial a political persecution and said it was aimed at blocking him running in the 2026 presidential election.
