Bolsonaro has been arrested after authorities concluded he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of planning a government overthrow in September and handed more than over two decades in jail, but he was staying under house arrest pending appeals.
Top Judicial Official Justice Moraes said the decision to arrest the elderly politician was a preventative measure after fresh information were revealed.
This involved trying to remove his tracking device and a invitation to a public vigil that could facilitate a chance to flee".
Judicial Records Show Escape Risks
In a document approving the custody, Justice Moraes said intelligence from the unit overseeing Bolsonaro's house arrest suggested the former leader's aim to disable the electronic ankle bracelet to secure accomplishment in his escape.
This, it said, would be assisted by the disorder caused by the demonstration called by his child.
His offspring, his son Flávio, who holds office as a legislator, called for a gathering of his followers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on social media on last Friday: "Are you going to fight for your nation, or see it all from your phone there on your settee? I call on you to fight with us."
He said the gathering would be so backers could "pray for his well-being and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the chance of his transfer to embassies near the residence, considering that the investigations revealed a record of organizing to seek refuge through a embassy office", a statement said.
The judicial paperwork emphasizes that the United States embassy in the capital, Brasilia, is located around 13km from Bolsonaro's home.
Worldwide Consequences
His judicial problems have generated frustration from fellow conservative nationalist American leader President Trump, prompting him to impose a 50% tariff on goods coming from Brazil.
The former president is being detained in a national police facility in the capital and will undergo a custody hearing 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 electronic monitoring.
They also requested that he be authorized to depart his residence for healthcare, saying he demanded regular treatment for lung conditions and other health problems.
Context of Sentencing
Bolsonaro was convicted of heading a plot aimed at keeping him in power after he lost the national vote to his political opponent, Lula.
High Court judges said that he was aware of a scheme which involved plans to assassinate his opponent and his vice-presidential running mate, his vice-presidential candidate, and to detain and kill Justice Moraes - the Supreme Court justice who has been managing his judicial proceedings.
The scheme was thwarted because it failed to get the endorsement of the military leaders. His successor was sworn in without issue on January 1st, 2023.
But a following week, on 8 January, thousands of his followers stormed and vandalised public facilities in the capital, Brasília.
The security forces stepped in and around 1,500 people were arrested.
The magistrates found that the demonstrators had been encouraged by him whose scheme, they said, was for the Brazilian military to step in, restore order and reinstate his authority.
At the time, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also banned from running for public office until the year 2060 - 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.
