Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under home confinement.
The one-time leader was convicted of orchestrating a military coup in September and given more than over two decades in incarceration, but he was staying under home detention pending appeals.
Brazilian Supreme Court Justice the presiding justice said the move to detain the elderly politician was a preventative measure after recent developments emerged.
This involved seeking to disable his tracking device and a summons to a supporters' gathering that could facilitate a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the one-time head of state's "intention to break the tracking monitor to secure accomplishment in his escape.
This, it said, would be "facilitated by the chaos caused by the protest called by his offspring.
His offspring, Flávio, who holds office as a congressional representative, called for a meeting of his followers near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on online platforms on Friday: Will you battle for your homeland, or watch it all from your smartphone there on your couch? I urge you to battle with us."
He said the demonstration would be so followers could offer prayers for his well-being and for the return of democracy in our land."
Foreign Shelter Risks
Part of the judge's determination was the chance of the former president's transfer to embassies near the home, considering that the investigations revealed a background of arranging to request asylum through a embassy office", a announcement said.
The court filing emphasizes that the US embassy in the capital, Brazil's capital, is positioned around 8 miles from his dwelling.
Global Responses
The former president's legal troubles have drawn the ire of fellow populist conservative United States President President Trump, leading him to implement a fifty percent tax on goods coming from Brazil.
The former president is being held in a federal law enforcement building in the capital and will undergo a custody hearing on the next day.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the Supreme Court to authorize him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also requested that Bolsonaro be authorized to exit his dwelling for medical care, saying he demanded ongoing care for lung conditions and other illnesses.
Context of Sentencing
He was convicted of heading a scheme aimed at retaining his authority after he failed to win the national vote to his political opponent, Lula.
Top judicial officials said that he was aware of a plan which included plans to assassinate the current president and his running partner, his vice-presidential candidate, and to imprison and murder Justice Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was prevented because it didn't receive the endorsement of the armed forces officials. The current president was took office without problem on the first day of 2023.
But a week later, on January 8th, many his backers stormed and vandalised official structures in the federal district, Brasília.
The law enforcement intervened and around 1,500 people were taken into custody.
The justices found that the rioters had been provoked by him whose scheme, they said, was for the Brazilian military to intervene, reestablish control and reinstate his authority.
At the period, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also banned from seeking elected position until 2060 - eight years after the end of his sentence.
The ex-leader called the court case a "witch hunt and said it was designed to prevent him competing in the next presidential race.
