Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of plotting a armed takeover in September and given more than 27 years in jail, but he was staying under confinement pending legal challenges.
High Court Judge the presiding justice said the action to imprison the 70-year-old politician was a safety action after recent developments were revealed.
This encompassed seeking to disable his ankle monitor and a call for a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Escape Concerns
In a filing authorising the arrest, the judge said data from the unit overseeing Bolsonaro's house arrest suggested the ex-president's "intention to break the surveillance device to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the gathering called by his child.
His offspring, Flávio Bolsonaro, who serves as a senator, called for a meeting of his backers near Bolsonaro's home to take place on Saturday night.
Flávio Bolsonaro wrote on social media on last Friday: Do you plan to struggle for your homeland, or watch it all from your phone there on your settee? I invite you to battle with us."
He said the gathering would be so backers could "pray for his well-being and for the reestablishment of democratic governance in our country."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of his move to embassies near the home, considering that the inquiries revealed a record of arranging to seek refuge through a consular facility", a declaration said.
The judicial paperwork highlights that the American diplomatic mission in the federal district, Brazil's capital, is positioned around 8 miles from the former president's residence.
Global Responses
His judicial problems have provoked anger from fellow conservative nationalist United States President Donald Trump, causing him to impose a half-rate duty on imports of Brazilian goods.
He is being detained in a federal law enforcement building in Brazil's capital city and will undergo a custody hearing on the following day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the High Court to allow him to fulfill his full incarceration period under home confinement, with electronic monitoring.
They also petitioned that the former president be allowed to depart his residence for medical treatment, saying he needed ongoing care for respiratory ailments and other health problems.
Context of Sentencing
The former president was convicted of leading a scheme aimed at keeping him in power after he failed to win the national vote to his political opponent, Lula.
Supreme Court justices said that he had knowledge of a plot which involved plans to murder his opponent and his running partner, Alckmin, and to imprison and murder Justice Moraes - the High Court judge who has been overseeing Bolsonaro's trial.
The scheme was prevented because it didn't receive the backing of the military leaders. The current president was inaugurated without issue on the first day of 2023.
But a seven days after, on the eighth of January, numerous Bolsonaro supporters attacked and damaged public facilities in the national capital, Brazil's capital.
The security forces took action and around approximately 1,500 persons were arrested.
The judges found that the demonstrators had been incited by him whose scheme, they said, was for the national armed forces to intervene, reestablish control and bring him back to power.
At the time, the legal team called the decades-long sentence "absurdly excessive.
He was also barred from seeking elected position until the year 2060 - a decade minus two years after the end of his sentence.
The one-time head of state called the court case a targeted investigation" and said it was aimed at blocking him competing in the 2026 national vote.
