Bolsonaro has been taken into custody after authorities found he posed a definite escape threat while under domestic detention.
The one-time leader was sentenced of plotting a military coup in last fall and given more than a 27-year term in prison, but he continued under home detention pending legal challenges.
Brazilian Supreme Court Justice Alexandre de Moraes said the decision to arrest the septuagenarian politician was a safety action after "new facts" emerged.
This encompassed seeking to disable his ankle monitor and a call for a demonstration that could enable a chance to flee".
Legal Document Reveals Flight Fears
In a filing authorising the detention, the judge said data from the facility tracking the former president's confinement suggested the one-time head of state's "intention to break the tracking monitor to guarantee victory in his getaway".
This, it said, would be assisted by the chaos caused by the gathering called by his child.
His offspring, Flávio, who serves as a legislator, called for a gathering of his backers near his father's house to take place on Saturday night.
His son wrote on digital networks on the previous day: Will you battle for your nation, or watch it all from your phone there on your couch? I invite you to struggle with us."
He said the demonstration would be so followers could "pray for his well-being and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the chance of his move to embassies near the residence, considering that the inquiries revealed a background of planning to ask for protection through a embassy office", a statement said.
The judicial paperwork underscores that the United States embassy in the capital, Brasilia, is located around 8 miles from the former president's residence.
Worldwide Consequences
The former president's legal troubles have generated frustration from fellow populist conservative American leader Donald Trump, causing him to enact a half-rate duty on imports of Brazilian goods.
The former president is being held in a federal law enforcement building in the capital and will experience a custody hearing on the next day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the Supreme Court to permit him to complete his entire prison term under domestic detention, with tracking devices.
They also requested that he be authorized to depart his residence for medical treatment, saying he needed frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
He was found guilty of leading a conspiracy aimed at keeping him in power after he lost the presidential race to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a scheme which involved plans to murder his opponent and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was stopped because it failed to get the support of the military leaders. His successor was sworn in without problem on the first day of 2023.
But a seven days after, on the eighth of January, thousands of Bolsonaro supporters invaded and destroyed government buildings in the federal district, Brazil's capital.
The police stepped in and around fifteen hundred individuals were taken into custody.
The justices found that the protesters had been incited by him whose scheme, they said, was for the national armed forces to take action, reestablish control and reinstate his authority.
At the period, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also banned from campaigning for office until 2060 - eight years after the conclusion of his imprisonment.
The ex-leader called the trial a targeted investigation" and said it was aimed at blocking him running in the next presidential race.
