Bolsonaro has been taken into custody after authorities concluded he posed a serious risk of fleeing while under house arrest.
The ex-president was convicted of planning a military coup in last fall and handed more than over two decades in jail, but he was staying under confinement pending appeals.
High Court Judge Alexandre de Moraes said the action to imprison the 70-year-old politician was a preventative measure after "new facts" emerged.
This encompassed trying to remove his tracking device and a invitation to a public vigil that could enable a possible escape.
Court Filing Details Escape Risks
In a filing authorising the arrest, Justice Moraes said information from the facility tracking the former president's confinement suggested the one-time head of state's plan to remove the surveillance device to secure accomplishment in his getaway".
This, it said, would be assisted by the chaos caused by the demonstration called by his child.
His offspring, Flávio, who works as a congressional representative, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your country, or observe everything from your phone there on your couch? I urge you to fight with us."
He said the demonstration would be so backers could seek divine intervention for his health and for the return of democracy in our land."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of the former president's move to foreign missions near the residence, considering that the investigations revealed a history of organizing to seek refuge through a diplomatic representation", a announcement said.
The judicial paperwork emphasizes that the United States embassy in the federal district, Brazil's capital, is located around 13km from his dwelling.
International Reactions
The former president's legal troubles have drawn the ire of fellow conservative nationalist United States President Donald Trump, prompting him to enact a 50% tariff on goods coming from Brazil.
He is being held in a federal law enforcement building in the capital and will experience a imprisonment assessment on the following day.
Recent Legal Requests
It was only on last Friday that the ex-leader's attorneys asked the Top Court to permit him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also asked that Bolsonaro be permitted to depart his residence for medical care, saying he required regular treatment for pulmonary infections and other health problems.
Background on Conviction
The former president was determined responsible of leading a scheme aimed at retaining his authority after he lost the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a scheme which involved plans to assassinate Lula and his running partner, his vice-presidential candidate, and to imprison and murder the presiding judge - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The conspiracy was stopped because it didn't receive the support of the military leaders. Lula was sworn in without incident on 1 January 2023.
But a week later, on January 8th, numerous his followers stormed and vandalised government buildings in the national capital, Brasília.
The law enforcement stepped in and around 1,500 people were detained.
The magistrates found that the protesters had been incited by Bolsonaro whose scheme, they said, was for the national armed forces to step in, bring back stability and bring him back to power.
At the moment, the legal team called the decades-long sentence unreasonably severe".
He was also prohibited from seeking elected position until twenty-sixty - eight years after the conclusion of his imprisonment.
The former president called the legal proceedings a targeted investigation" and said it was intended to stop him competing in the 2026 national vote.
