Bolsonaro has been detained after authorities found he posed a definite escape threat while under home confinement.
The ex-president was convicted of plotting a military coup in September and given more than 27 years in incarceration, but he remained under confinement pending court reviews.
Brazilian Supreme Court Justice Alexandre de Moraes said the action to imprison the septuagenarian politician was a preventative measure after fresh information were revealed.
This encompassed trying to remove his ankle monitor and a summons to a supporters' gathering that could "allow for a potential flight.
Judicial Records Show Escape Risks
In a document approving the arrest, the magistrate said intelligence from the centre monitoring his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his son.
His child, Flávio, who serves as a senator, called for a assembly of his followers near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on last Friday: "Are you going to fight for your homeland, or observe everything from your phone there on your sofa? I urge you to struggle with us."
He said the gathering would be so followers could "pray for his health and for the return of democracy in our land."
Foreign Shelter Risks
Part of Justice Moraes's decision was the potential of Bolsonaro's move to foreign missions near the home, considering that the probes revealed a record of arranging to seek refuge through a consular facility", a statement said.
The judicial paperwork emphasizes that the US embassy in the capital, Brasilia, is positioned around approximately 13 kilometers from the former president's residence.
International Reactions
His judicial problems have provoked anger from fellow conservative nationalist American leader Donald Trump, prompting him to impose a half-rate duty on imports of Brazilian goods.
He is being detained in a Federal Police station in Brasilia and will undergo a detention review on the next day.
Recent Judicial Appeals
It was only on Friday that the former president's lawyers asked the High Court to authorize him to fulfill his full incarceration period under home confinement, with tracking devices.
They also petitioned that Bolsonaro be authorized to exit his dwelling for healthcare, saying he demanded ongoing care for respiratory ailments and other ailments.
Context of Sentencing
He was determined responsible of heading a conspiracy aimed at keeping him in power after he was defeated in the 2022 election to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a plan which encompassed plans to kill the current president and his VP candidate, Geraldo Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was stopped because it failed to get the endorsement of the army and air force commanders. His successor was took office without incident on January 1st, 2023.
But a following week, on January 8th, many his backers stormed and vandalised public facilities in the capital, the capital city.
The police intervened and around approximately 1,500 persons were detained.
The magistrates found that the rioters had been provoked by him whose plan, they said, was for the Brazilian military to step in, reestablish control and bring him back to power.
At the moment, the legal team called the decades-long sentence extremely harsh.
He was also barred from campaigning for office until 2060 - a decade minus two years after the completion of his term.
The ex-leader called the trial a political persecution and said it was designed to prevent him running in the next presidential race.
