Bolsonaro has been detained after authorities determined he posed a definite escape threat while under domestic detention.
The former head of state was sentenced of plotting a armed takeover in last fall and sentenced more than over two decades in jail, but he continued under confinement pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the 70-year-old politician was a safety action after fresh information emerged.
This involved seeking to disable his tracking device and a invitation to a demonstration that could facilitate a chance to flee".
Legal Document Reveals Flight Fears
In a filing authorising the detention, Justice Moraes said information from the centre monitoring his home detention suggested the ex-president's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be "facilitated by the confusion caused by the demonstration called by his child.
His son, Flávio Bolsonaro, who works as a senator, called for a meeting of his supporters near Bolsonaro's home to take place on Saturday night.
Flávio Bolsonaro wrote on social media on last Friday: Will you battle for your homeland, or see it all from your smartphone there on your settee? I call on you to fight with us."
He said the gathering would be so backers could seek divine intervention for his health and for the return of democracy in our nation."
Foreign Shelter Risks
Part of the judge's ruling was the possibility of the former president's transfer to foreign missions near the dwelling, considering that the inquiries revealed a history of arranging to seek refuge through a diplomatic representation", a announcement said.
The court filing highlights that the United States embassy in the capital, Brasilia, is situated around approximately 13 kilometers from the former president's residence.
International Reactions
The former president's legal troubles have drawn the ire of fellow populist conservative US President Donald Trump, causing him to enact a half-rate duty on imports of Brazilian goods.
Bolsonaro is being held in a Federal Police station in Brazil's capital city and will undergo a detention review on Sunday.
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 allowed to leave his home for healthcare, saying he needed frequent medical attention for lung conditions and other illnesses.
Background on Conviction
He was found guilty of heading a scheme aimed at keeping him in power after he was defeated in the national vote to his ideological adversary, President Lula.
Supreme Court justices said that he had knowledge of a plot which included plans to assassinate the current president and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was thwarted because it didn't receive the backing of the armed forces officials. The current president was inaugurated without incident on January 1st, 2023.
But a following week, on January 8th, many Bolsonaro supporters stormed and vandalised official structures in the federal district, the capital city.
The police stepped in and around approximately 1,500 persons were taken into custody.
The justices found that the demonstrators had been encouraged by Bolsonaro whose strategy, they said, was for the Brazilian military to intervene, reestablish control and bring him back to power.
At the period, his attorneys called the over 27-year sentence unreasonably severe".
He was also barred from campaigning for office until twenty-sixty - eight years later after the end of his sentence.
The ex-leader called the trial a political persecution and said it was aimed at blocking him competing in the next presidential race.
