The former Brazilian leader has been arrested after authorities found he posed a concrete flight risk while under home confinement.
The former head of state was convicted of planning a government overthrow in September and handed more than 27 years in prison, but he remained under confinement pending legal challenges.
High Court Judge Justice Moraes said the move to detain the elderly politician was a precautionary step after fresh information came to light.
This involved seeking to disable his tracking device and a call for a supporters' gathering that could "allow for a chance to flee".
Legal Document Reveals Flight Fears
In a document approving the arrest, the magistrate said intelligence from the centre monitoring his home detention suggested the ex-president's aim to disable the tracking monitor to ensure success in his escape.
This, it said, would be "facilitated by the confusion caused by the protest called by his son.
His child, Flávio Bolsonaro, who works as a congressional representative, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on digital networks on the previous day: Do you plan to struggle for your nation, or watch it all from your phone there on your settee? I invite you to struggle with us."
He said the demonstration would be so followers could "pray for his health and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the judge's determination was the chance of the former president's move to diplomatic missions near the home, considering that the inquiries revealed a history of planning to request asylum through a embassy office", a declaration said.
The judicial paperwork emphasizes that the United States embassy in the capital, the capital city, is positioned around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
The former president's legal troubles have provoked anger from fellow conservative nationalist American leader Donald Trump, prompting him to impose a 50% tariff on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the Top Court to permit him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also asked that he be allowed to exit his dwelling for healthcare, saying he demanded regular treatment for lung conditions and other health problems.
Context of Sentencing
Bolsonaro was determined responsible of leading a conspiracy aimed at retaining his authority after he failed to win the 2022 election to his ideological adversary, President Lula.
Top judicial officials said that he had knowledge of a scheme which encompassed plans to assassinate his opponent and his running partner, Geraldo Alckmin, and to imprison and murder the presiding judge - the High Court judge who has been presiding over Bolsonaro's trial.
The plot was prevented because it failed to get the backing of the army and air force commanders. His successor was inaugurated without issue on the first day of 2023.
But a following week, on the eighth of January, numerous his backers stormed and vandalised government buildings in the federal district, Brazil's capital.
The law enforcement took action and around 1,500 people were taken into custody.
The judges found that the demonstrators had been provoked by Bolsonaro whose scheme, they said, was for the country's army to take action, restore order and return him to office.
At the period, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also barred from seeking elected position until the year 2060 - eight years after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a "witch hunt and said it was aimed at blocking him competing in the 2026 national vote.
