Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under domestic detention.
The former head of state was found guilty of orchestrating a military coup in the ninth month and given more than 27 years in prison, but he continued under house arrest pending legal challenges.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a preventative measure after "new facts" were revealed.
This included seeking to disable his electronic bracelet and a summons to a demonstration that could "allow for a possible escape.
Court Filing Details Flight Fears
In a document approving the arrest, the judge said information from the facility tracking his home detention suggested the one-time head of state's aim to disable the surveillance device to ensure success in his escape.
This, it said, would be assisted by the disorder caused by the protest called by his son.
His child, his son Flávio, who holds office as a senator, called for a assembly of his followers near the former president's residence to take place on Saturday night.
His son wrote on online platforms on last Friday: Will you battle for your country, or see it all from your mobile device there on your couch? I urge you to battle with us."
He said the vigil would be so followers could offer prayers for his health and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of the judge's decision was the chance of his transfer to embassies near the dwelling, considering that the probes revealed a history of organizing to seek refuge through a embassy office", a announcement said.
The judicial paperwork highlights that the American diplomatic mission in the federal district, Brasilia, is positioned around 8 miles from Bolsonaro's home.
Worldwide Consequences
His judicial problems have drawn the ire of fellow populist conservative United States President Donald Trump, leading him to enact a 50% tariff on goods coming from Brazil.
The former president is being held in a national police facility in Brazil's capital city and will experience a imprisonment assessment on the following day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Top Court to authorize him to fulfill his full incarceration period under domestic detention, with tracking devices.
They also asked that the former president be authorized to depart his residence for medical care, saying he demanded frequent medical attention for pulmonary infections and other illnesses.
Context of Sentencing
He was convicted of leading a conspiracy aimed at keeping him in power after he lost the presidential race to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he was aware of a plan which involved plans to kill Lula and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill Justice Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The plot was thwarted because it failed to get the backing of the armed forces officials. Lula was inaugurated without issue on the first day of 2023.
But a week later, on 8 January, numerous Bolsonaro supporters invaded and destroyed official structures in the capital, the capital city.
The law enforcement intervened and around fifteen hundred individuals were detained.
The justices found that the rioters had been incited by Bolsonaro whose strategy, they said, was for the Brazilian military to take action, restore order and reinstate his authority.
At the time, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also prohibited from seeking elected position until twenty-sixty - eight years after the end of his sentence.
The one-time head of state called the court case a political persecution and said it was intended to stop him participating in the 2026 national vote.
