Bolsonaro has been taken into custody after authorities determined he posed a definite escape threat while under house arrest.
The one-time leader was found guilty of plotting a government overthrow in September and given more than over two decades in prison, but he remained under home detention pending legal challenges.
Top Judicial Official Justice Moraes said the move to detain the septuagenarian politician was a safety action after fresh information emerged.
This encompassed attempting to break his ankle monitor and a invitation to a supporters' gathering that could facilitate a potential flight.
Court Filing Details Escape Concerns
In a paperwork permitting the arrest, the judge said data from the centre monitoring his home detention suggested the one-time head of state's "intention to break the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the chaos caused by the gathering called by his son.
His child, Flávio, who works as a senator, called for a meeting of his followers near Bolsonaro's home to take place on Saturday night.
His son wrote on digital networks on last Friday: "Are you going to fight for your nation, or watch it all from your mobile device there on your sofa? I urge you to struggle with us."
He said the demonstration would be so supporters could offer prayers for his physical condition and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of the judge's ruling was the potential of Bolsonaro's move to foreign missions near the residence, considering that the investigations revealed a record of organizing to request asylum through a consular facility", a statement said.
The judicial paperwork underscores that the United States embassy in the federal district, Brazil's capital, is positioned around 13km from Bolsonaro's home.
Worldwide Consequences
His judicial problems have generated frustration from fellow right-wing populist United States President Donald Trump, prompting him to enact a fifty percent tax on Brazilian product imports.
He is being kept in a Federal Police station in Brasilia and will undergo a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the Supreme Court to authorize him to complete his entire prison term under home confinement, with digital surveillance.
They also requested that he be allowed to depart his residence for healthcare, saying he required regular treatment for pulmonary infections and other ailments.
Details of Guilty Verdict
The former president was determined responsible of leading a scheme aimed at keeping him in power after he was defeated in the national vote to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plot which involved plans to assassinate his opponent and his vice-presidential running mate, Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been presiding over the former president's case.
The plot was stopped because it didn't receive the support of the armed forces officials. Lula was sworn in without incident on the first day of 2023.
But a seven days after, on 8 January, thousands of Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brasília.
The police took action and around fifteen hundred individuals were detained.
The magistrates found that the protesters had been encouraged by Bolsonaro whose plan, they said, was for the Brazilian military to intervene, reestablish control and reinstate his authority.
At the moment, the legal team called the 27 years and three months sentence unreasonably severe".
He was also prohibited from seeking elected position until the year 2060 - eight years later after the completion of his term.
The one-time head of state called the court case a political persecution and said it was designed to prevent him participating in the 2026 national vote.
