The former Brazilian leader has been detained after authorities determined he posed a serious risk of fleeing while under domestic detention.
The one-time leader was sentenced of plotting a military coup in the ninth month and handed more than a 27-year term in incarceration, but he continued under confinement pending appeals.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the septuagenarian politician was a safety action after "new facts" came to light.
This included seeking to disable his tracking device and a summons to a demonstration that could facilitate a possible escape.
Legal Document Reveals Escape Risks
In a filing authorising the detention, Justice Moraes said intelligence from the facility tracking Bolsonaro's house arrest suggested the former leader's "intention to break the electronic ankle bracelet to ensure success in his escape.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his offspring.
His offspring, his son Flávio, who serves as a congressional representative, called for a assembly of his backers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on last Friday: "Are you going to fight for your nation, or observe everything from your smartphone there on your couch? I invite you to struggle with us."
He said the demonstration would be so followers could "pray for his health and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the potential of his move to diplomatic missions near the residence, considering that the inquiries revealed a history of arranging to ask for protection through a consular facility", a declaration said.
The court filing highlights that the US embassy in the federal district, the capital city, is situated around 13km from Bolsonaro's home.
International Reactions
His judicial problems have drawn the ire of fellow right-wing populist American leader President Trump, prompting him to impose a fifty percent tax on imports of Brazilian goods.
Bolsonaro is being held in a federal law enforcement building in Brasilia and will undergo a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on Friday that the his legal team asked the Supreme Court to allow him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also requested that he be permitted to leave his home for medical care, saying he needed regular treatment for respiratory ailments and other health problems.
Details of Guilty Verdict
He was convicted of heading a scheme aimed at retaining his authority after he lost the presidential race to his political opponent, Lula.
Supreme Court justices said that he had knowledge of a scheme which included plans to assassinate the current president and his vice-presidential running mate, Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been managing his judicial proceedings.
The plot was stopped because it didn't receive the backing of the armed forces officials. The current president was inaugurated without incident on 1 January 2023.
But a seven days after, on 8 January, thousands of his backers attacked and damaged government buildings in the federal district, Brazil's capital.
The security forces intervened and around 1,500 people were arrested.
The magistrates found that the rioters had been provoked by Bolsonaro whose scheme, they said, was for the country's army to step in, bring back stability and return him to office.
At the moment, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until 2060 - eight years later after the end of his sentence.
The one-time head of state called the trial a targeted investigation" and said it was aimed at blocking him participating in the 2026 presidential election.
