Jair Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The ex-president was found guilty of plotting a armed takeover in September and given more than a 27-year term in incarceration, but he was staying under home detention pending appeals.
Top Judicial Official Justice Moraes said the move to detain the 70-year-old politician was a safety action after recent developments were revealed.
This encompassed attempting to break his electronic bracelet and a summons to a public vigil that could enable a potential flight.
Court Filing Details Escape Concerns
In a filing authorising the detention, the judge said intelligence from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's plan to remove the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the chaos caused by the protest called by his offspring.
His child, his son Flávio, who holds office as a congressional representative, called for a meeting of his followers near Bolsonaro's home to take place on Saturday night.
His son wrote on digital networks on the previous day: Will you battle for your homeland, or watch it all from your mobile device there on your couch? I invite you to struggle with us."
He said the gathering would be so backers could offer prayers for his health and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the judge's decision was the possibility of the former president's transfer to diplomatic missions near the home, considering that the investigations revealed a background of organizing to request asylum through a embassy office", a declaration said.
The court filing highlights that the US embassy in the federal district, the capital city, is positioned around approximately 13 kilometers from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have provoked anger from fellow conservative nationalist United States President President Trump, leading him to implement a half-rate duty on imports of Brazilian goods.
He is being held in a federal law enforcement building in Brasilia and will have a imprisonment assessment on the next day.
Latest Court Petitions
It was only on Friday that the his legal team asked the High Court to allow him to complete his entire prison term under home confinement, with digital surveillance.
They also asked that Bolsonaro be allowed to exit his dwelling for medical care, saying he required ongoing care for respiratory ailments and other ailments.
Details of Guilty Verdict
The former president was determined responsible of leading a scheme aimed at retaining his authority after he failed to win the presidential race to his left-wing rival, President Lula.
High Court judges said that he had knowledge of a scheme which encompassed plans to assassinate the current president and his running partner, Alckmin, and to imprison and murder Alexandre de Moraes - the High Court judge who has been managing the former president's case.
The conspiracy was thwarted because it didn't receive the support of the army and air force commanders. Lula was took office without incident on the first day of 2023.
But a week later, on the eighth of January, thousands of his backers attacked and damaged government buildings in the national capital, Brasília.
The security forces took action and around approximately 1,500 persons were taken into custody.
The justices found that the demonstrators had been provoked by him whose plan, they said, was for the country's army to intervene, bring back stability and return him to office.
At the moment, his attorneys called the over 27-year sentence unreasonably severe".
He was also barred from campaigning for office until the year 2060 - eight years after the conclusion of his imprisonment.
The one-time head of state called the trial a "witch hunt and said it was designed to prevent him running in the 2026 presidential election.
