Bolsonaro has been detained after authorities found he posed a concrete flight risk while under domestic detention.
The former head of state was sentenced of plotting a armed takeover in September and given more than over two decades in incarceration, but he continued under house arrest pending legal challenges.
Brazilian Supreme Court Justice Alexandre de Moraes said the action to imprison the 70-year-old politician was a safety action after fresh information were revealed.
This involved attempting to break his electronic bracelet and a invitation to a demonstration that could "allow for a potential flight.
Court Filing Details Escape Risks
In a filing authorising the custody, the judge said data from the centre monitoring Bolsonaro's house arrest suggested the ex-president's "intention to break the electronic ankle bracelet to ensure success in his getaway".
This, it said, would be assisted by the chaos caused by the protest called by his offspring.
His offspring, his son Flávio, who works as a senator, called for a gathering of his followers near Bolsonaro's home to take place on the weekend.
His son wrote on social media on Friday: Do you plan to struggle for your nation, or observe everything from your smartphone there on your settee? I invite you to struggle with us."
He said the demonstration would be so followers could offer prayers for his physical condition and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the magistrate's determination was the chance of the former president's move to foreign missions near the residence, considering that the investigations revealed a record of planning to ask for protection through a diplomatic representation", a statement said.
The legal document underscores that the US embassy in the federal district, Brazil's capital, is positioned around 13km from his dwelling.
Global Responses
His judicial problems have generated frustration from fellow populist conservative United States President President Trump, prompting him to impose a fifty percent tax on Brazilian product imports.
He is being held in a federal law enforcement building in the capital and will have a imprisonment assessment on the next day.
Recent Legal Requests
It was only on the previous day that the former president's lawyers asked the Supreme Court to permit him to complete his entire prison term under domestic detention, with digital surveillance.
They also asked that the former president be allowed to depart his residence for medical care, saying he required ongoing care for lung conditions and other illnesses.
Context of Sentencing
He was found guilty of orchestrating a plot aimed at keeping him in power after he lost the presidential race to his ideological adversary, President Lula.
Supreme Court justices said that he was aware of a scheme which included plans to murder Lula and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder Alexandre de Moraes - the High Court judge who has been presiding over Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the backing of the military leaders. His successor was sworn in without problem on 1 January 2023.
But a following week, on 8 January, many his backers invaded and destroyed government buildings in the capital, Brasília.
The security forces stepped in and around 1,500 people were taken into custody.
The magistrates found that the rioters had been provoked by the former president whose strategy, they said, was for the Brazilian military to intervene, restore order and bring him back to power.
At the time, his attorneys called the 27 years and three months sentence extremely harsh.
He was also banned from campaigning for office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The ex-leader called the legal proceedings a targeted investigation" and said it was aimed at blocking him competing in the 2026 presidential election.
