Jair Bolsonaro has been detained after authorities concluded he posed a concrete flight risk while under domestic detention.
The former head of state was sentenced of planning a armed takeover in the ninth month and given more than 27 years in jail, but he continued under confinement pending court reviews.
High Court Judge Justice Moraes said the move to detain the 70-year-old politician was a preventative measure after fresh information came to light.
This included attempting to break his electronic bracelet and a summons to a supporters' gathering that could enable a possible escape.
Court Filing Details Escape Risks
In a paperwork permitting the arrest, the judge said data from the unit overseeing his home detention 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 confusion caused by the demonstration called by his son.
His son, his son Flávio, who works as a congressional representative, called for a gathering of his followers near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on social media on last Friday: Do you plan to struggle for your homeland, or see it all from your smartphone there on your sofa? I urge you to fight with us."
He said the vigil would be so followers could seek divine intervention for his well-being and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of the judge's ruling was the potential of the former president's "relocation to diplomatic missions near the home, considering that the probes revealed a history of organizing to seek refuge through a consular facility", a statement said.
The court filing highlights that the US embassy in the federal district, the capital city, is positioned around 13km from the former president's residence.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow populist conservative United States President Donald Trump, prompting him to impose a fifty percent tax on imports of Brazilian goods.
He is being detained in a Federal Police station in the capital and will undergo a detention review on the following day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also asked that the former president be permitted to depart his residence for healthcare, saying he required regular treatment for respiratory ailments and other illnesses.
Details of Guilty Verdict
The former president was convicted of heading a conspiracy aimed at maintaining his control after he was defeated in the national vote to his left-wing rival, Lula.
High Court judges said that he was aware of a plan which involved plans to kill his opponent and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the High Court judge who has been overseeing his judicial proceedings.
The conspiracy was stopped because it couldn't obtain the support of the army and air force commanders. Lula was sworn in without incident on January 1st, 2023.
But a following week, on January 8th, many his followers attacked and damaged public facilities in the federal district, Brazil's capital.
The police intervened and around 1,500 people were arrested.
The magistrates found that the demonstrators had been provoked by him whose plan, they said, was for the national armed forces to step in, bring back stability and return him to office.
At the time, the legal team called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - a decade minus two years after the conclusion of his imprisonment.
The former president called the court case a "witch hunt and said it was aimed at blocking him participating in the 2026 presidential election.
