Jair Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The ex-president was convicted of plotting a government overthrow in the ninth month and handed more than a 27-year term in prison, but he was staying under confinement pending court reviews.
Top Judicial Official Justice Moraes said the action to imprison the 70-year-old politician was a precautionary step after recent developments emerged.
This encompassed seeking to disable his electronic bracelet and a invitation to a public vigil that could "allow for a potential flight.
Legal Document Reveals Escape Risks
In a paperwork permitting the arrest, Justice Moraes said intelligence from the centre monitoring his home detention suggested the one-time head of state's plan to remove the tracking monitor to ensure success in his flight.
This, it said, would be "facilitated by the chaos caused by the gathering called by his child.
His child, his son Flávio, who works as a legislator, called for a gathering of his followers near the former president's residence to take place on Saturday night.
The senator wrote on online platforms on the previous day: Do you plan to struggle for your homeland, or observe everything from your mobile device there on your settee? I invite you to battle with us."
He said the vigil would be so backers could offer prayers for his well-being and for the reestablishment of democratic governance in our country."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the chance of Bolsonaro's move to foreign missions near the residence, considering that the inquiries revealed a record of arranging to seek refuge through a embassy office", a statement said.
The court filing underscores that the United States embassy in the national capital, Brasilia, is located around approximately 13 kilometers from his dwelling.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President Donald Trump, leading him to implement a half-rate duty on goods coming from Brazil.
The former president is being held in a federal law enforcement building in Brazil's capital city and will have a custody hearing on the next day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Top Court to allow him to complete his entire prison term under home confinement, with electronic monitoring.
They also asked that he be permitted to leave his home for healthcare, saying he required ongoing care for pulmonary infections and other health problems.
Context of Sentencing
The former president was determined responsible of heading a scheme aimed at keeping him in power after he lost the national vote to his left-wing rival, President Lula.
High Court judges said that he had knowledge of a scheme which encompassed plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been overseeing Bolsonaro's trial.
The plot was prevented because it couldn't obtain the backing of the military leaders. The current president was took office without incident on the first day of 2023.
But a week later, on the eighth of January, many Bolsonaro supporters invaded and destroyed official structures in the national capital, Brasília.
The law enforcement intervened and around approximately 1,500 persons were detained.
The magistrates found that the demonstrators had been incited by Bolsonaro whose plan, they said, was for the national armed forces to step in, bring back stability and reinstate his authority.
At the time, the legal team called the decades-long sentence unreasonably severe".
He was also barred from running for public office until twenty-sixty - eight years later after the end of his sentence.
The ex-leader called the trial a targeted investigation" and said it was designed to prevent him running in the 2026 national vote.
