Jair Bolsonaro has been taken into custody 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 the ninth month and handed more than a 27-year term in prison, but he remained under home detention pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the elderly politician was a preventative measure after recent developments came to light.
This included attempting to break his ankle monitor and a invitation to a demonstration that could "allow for a possible escape.
Judicial Records Show Escape Concerns
In a filing authorising the custody, the judge said information from the centre monitoring his home detention suggested the ex-president's aim to disable the tracking monitor to ensure success in his getaway".
This, it said, would be made easier by the chaos caused by the gathering called by his son.
His son, his son Flávio, who holds office as a legislator, called for a assembly of his backers near the former president's residence to take place on Saturday evening.
His son wrote on social media on last Friday: Will you battle for your nation, or observe everything from your phone there on your settee? I invite you to battle with us."
He said the vigil would be so backers could "pray for his well-being and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of his transfer to diplomatic missions near the dwelling, considering that the probes revealed a history of arranging to ask for protection through a diplomatic representation", a declaration said.
The legal document highlights that the United States embassy in the capital, Brasilia, is positioned around 8 miles from his dwelling.
Global Responses
The former president's legal troubles have generated frustration from fellow populist conservative United States President Trump, causing him to implement a half-rate duty on imports of Brazilian goods.
He is being detained in a Federal Police station in Brazil's capital city and will experience a imprisonment assessment on Sunday.
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 the former president be allowed to leave his home for medical care, saying he needed ongoing care for respiratory ailments and other illnesses.
Context of Sentencing
The former president was determined responsible of leading a conspiracy aimed at maintaining his control after he lost the 2022 election to his political opponent, Lula.
Top judicial officials said that he had knowledge of a scheme which involved plans to kill Lula and his running partner, his vice-presidential candidate, and to imprison and murder the presiding judge - the High Court judge who has been overseeing his judicial proceedings.
The conspiracy was thwarted because it failed to get the support of the military leaders. Lula was took office without problem on the first day of 2023.
But a seven days after, on the eighth of January, numerous Bolsonaro supporters attacked and damaged official structures in the capital, Brazil's capital.
The police intervened and around approximately 1,500 persons were detained.
The magistrates found that the rioters had been provoked by him whose strategy, they said, was for the national armed forces to step in, restore order and bring him back to power.
At the moment, the legal team called the over 27-year sentence unreasonably severe".
He was also barred from running for public office until twenty-sixty - eight years after the conclusion of his imprisonment.
The one-time head of state called the court case a "witch hunt and said it was aimed at blocking him participating in the 2026 presidential election.
