Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under home confinement.
The former head of state was sentenced of plotting a armed takeover in September and given more than over two decades in prison, but he continued under confinement pending appeals.
High Court Judge Justice Moraes said the action to imprison the elderly politician was a preventative measure after recent developments came to light.
This encompassed seeking to disable his electronic bracelet and a call for a public vigil that could facilitate a potential flight.
Legal Document Reveals Flight Fears
In a document approving the custody, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the former leader's "intention to break the tracking monitor to ensure success in his escape.
This, it said, would be assisted by the chaos caused by the demonstration called by his offspring.
His son, Flávio Bolsonaro, who serves as a congressional representative, called for a gathering of his backers near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on last Friday: Do you plan to struggle for your homeland, or see it all from your phone there on your sofa? I call on you to struggle with us."
He said the gathering would be so backers could offer prayers for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of Bolsonaro's move to foreign missions near the residence, considering that the probes revealed a background of arranging to seek refuge through a diplomatic representation", a announcement said.
The court filing emphasizes that the United States embassy in the capital, Brasilia, is located around 13km from his dwelling.
International Reactions
The former president's legal troubles have generated frustration from fellow conservative nationalist American leader President Trump, causing him to enact a fifty percent tax on goods coming from Brazil.
The former president is being detained in a national police facility in the capital and will undergo a imprisonment assessment on the next day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the Supreme Court to allow him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that the former president be allowed to exit his dwelling for healthcare, saying he needed frequent medical attention for respiratory ailments and other illnesses.
Background on Conviction
He was found guilty of heading a plot aimed at retaining his authority after he was defeated in the 2022 election to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which encompassed plans to assassinate his opponent and his VP candidate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been overseeing his judicial proceedings.
The plot was prevented because it failed to get the support of the military leaders. His successor was sworn in without incident on January 1st, 2023.
But a week later, on 8 January, numerous his followers invaded and destroyed official structures in the national capital, Brasília.
The law enforcement stepped in and around 1,500 people were arrested.
The judges found that the rioters had been provoked by the former president whose scheme, they said, was for the Brazilian military to step in, bring back stability and return him to office.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the court case a "witch hunt and said it was aimed at blocking him competing in the next presidential race.
