Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under domestic detention.
The former head of state was sentenced of plotting a government overthrow in September and given more than over two decades in incarceration, but he remained under confinement pending legal challenges.
Brazilian Supreme Court Justice Alexandre de Moraes said the decision to arrest the 70-year-old politician was a preventative measure after fresh information emerged.
This encompassed seeking to disable his electronic bracelet and a invitation to a supporters' gathering that could "allow for a chance to flee".
Judicial Records Show Escape Concerns
In a paperwork permitting the arrest, Justice Moraes said information from the unit overseeing the former president's confinement suggested the ex-president's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the disorder caused by the demonstration called by his offspring.
His son, Flávio, who works as a senator, called for a assembly of his supporters near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on online platforms on Friday: Do you plan to struggle for your country, or see it all from your mobile device there on your settee? I invite you to struggle with us."
He said the vigil would be so followers could "pray for his health and for the reestablishment of democratic governance in our land."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the possibility of his transfer to diplomatic missions near the residence, considering that the probes revealed a background of arranging to ask for protection through a embassy office", a declaration said.
The court filing highlights that the US embassy in the federal district, the capital city, is situated around approximately 13 kilometers from his dwelling.
International Reactions
His judicial problems have provoked anger from fellow populist conservative United States President Donald Trump, prompting him to enact a fifty percent tax on goods coming from Brazil.
Bolsonaro is being held in a federal law enforcement building in the capital and will experience a custody hearing on the following day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the High Court to authorize him to serve his whole jail sentence under house arrest, with tracking devices.
They also asked that the former president be allowed to depart his residence for healthcare, saying he needed ongoing care for pulmonary infections and other ailments.
Details of Guilty Verdict
Bolsonaro was convicted of orchestrating a scheme aimed at retaining his authority after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he had knowledge of a plan which encompassed plans to kill his opponent and his VP candidate, Geraldo Alckmin, and to imprison and murder Justice Moraes - the top judicial official who has been overseeing the former president's case.
The conspiracy was prevented because it couldn't obtain the endorsement of the army and air force commanders. The current president was inaugurated without issue on January 1st, 2023.
But a seven days after, on 8 January, many Bolsonaro supporters attacked and damaged official structures in the federal district, Brasília.
The law enforcement stepped in and around 1,500 people were detained.
The judges found that the protesters had been provoked by Bolsonaro whose scheme, they said, was for the Brazilian military to step in, reestablish control and reinstate his authority.
At the moment, the legal team called the over 27-year sentence unreasonably severe".
He was also prohibited from seeking elected position until 2060 - eight years later after the end of his sentence.
The former president called the trial a targeted investigation" and said it was aimed at blocking him participating in the 2026 national vote.
