Jair Bolsonaro has been arrested after authorities found he posed a definite escape threat while under domestic detention.
The one-time leader was sentenced of orchestrating a government overthrow in the ninth month and given more than a 27-year term in prison, but he remained under house arrest pending court reviews.
Brazilian Supreme Court Justice Alexandre de Moraes said the action to imprison the elderly politician was a preventative measure after fresh information emerged.
This encompassed seeking to disable his electronic bracelet and a summons to a public vigil that could facilitate a possible escape.
In a filing authorising the custody, the judge said intelligence from the centre monitoring Bolsonaro's house arrest suggested the former leader's aim to disable the tracking monitor to ensure success in his escape.
This, it said, would be assisted by the disorder caused by the demonstration called by his offspring.
His child, Flávio Bolsonaro, 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.
The senator wrote on online platforms on Friday: Will you battle for your nation, or see it all from your mobile device there on your settee? I call on you to battle with us."
He said the gathering would be so followers could seek divine intervention for his well-being and for the reestablishment of democratic governance in our country."
Part of Justice Moraes's decision was the chance of his transfer to foreign missions near the dwelling, considering that the inquiries revealed a history of planning to ask for protection through a consular facility", a announcement said.
The legal document highlights that the United States embassy in the federal district, Brasilia, is situated around 8 miles from his dwelling.
His judicial problems have drawn the ire of fellow populist conservative United States President Donald Trump, causing him to enact a fifty percent tax on Brazilian product imports.
Bolsonaro is being detained in a Federal Police station in the capital and will have a detention review on the next day.
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to permit him to serve his whole jail sentence under home confinement, with electronic monitoring.
They also petitioned that he be allowed to depart his residence for medical treatment, saying he required frequent medical attention for respiratory ailments and other ailments.
Bolsonaro was convicted of orchestrating a scheme aimed at maintaining his control after he failed to win the national vote to his ideological adversary, President Lula.
High Court judges said that he was aware of a plot which encompassed plans to assassinate his opponent and his running partner, Alckmin, and to detain and kill the presiding judge - the High Court judge who has been managing Bolsonaro's trial.
The scheme was thwarted because it couldn't obtain the endorsement of the army and air force commanders. His successor was took office without incident on the first day of 2023.
But a following week, on the eighth of January, numerous Bolsonaro supporters stormed and vandalised government buildings in the national capital, Brasília.
The security forces took action and around approximately 1,500 persons were arrested.
The justices found that the protesters had been incited by him whose strategy, they said, was for the Brazilian military to take action, reestablish control and reinstate his authority.
At the time, his attorneys called the over 27-year sentence "absurdly excessive.
He was also banned from seeking elected position until 2060 - a decade minus two years after the conclusion of his imprisonment.
The former president called the court case a political persecution and said it was designed to prevent him competing in the 2026 national vote.
