Bolsonaro has been taken into custody after authorities concluded he posed a concrete flight risk while under home confinement.
The one-time leader was convicted of orchestrating a armed takeover in September and given more than over two decades in incarceration, but he remained under confinement pending court reviews.
High Court Judge Alexandre de Moraes said the move to detain the elderly politician was a precautionary step after fresh information came to light.
This included attempting to break his ankle monitor and a summons to a demonstration that could facilitate a chance to flee".
Judicial Records Show Escape Risks
In a paperwork permitting the detention, the magistrate said data from the centre monitoring Bolsonaro's house arrest suggested the ex-president's plan to remove the surveillance device to ensure success in his getaway".
This, it said, would be "facilitated by the disorder caused by the demonstration called by his child.
His son, Flávio Bolsonaro, who works as a legislator, called for a assembly of his supporters near his father's house to take place on the weekend.
His son wrote on online platforms on last Friday: Will you battle for your country, or watch it all from your smartphone there on your settee? I urge you to struggle with us."
He said the demonstration would be so followers could offer prayers for his physical condition and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the judge's decision was the potential of the former president's "relocation to diplomatic missions near the home, considering that the probes revealed a history of arranging to ask for protection through a consular facility", a announcement said.
The court filing highlights that the United States embassy in the national capital, the capital city, is situated around approximately 13 kilometers from his dwelling.
International Reactions
The former president's legal troubles have provoked anger from fellow populist conservative US President Donald Trump, prompting him to implement a fifty percent tax on Brazilian product imports.
The former president is being detained in a Federal Police station in the capital and will experience a detention review on the next day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the Supreme Court to permit him to serve his whole jail sentence under home confinement, with tracking devices.
They also petitioned that he be authorized to depart his residence for healthcare, saying he needed frequent medical attention for lung conditions and other ailments.
Details of Guilty Verdict
He was found guilty of leading a plot aimed at retaining his authority after he lost the national vote to his political opponent, Lula.
High Court judges said that he knew of a scheme which involved plans to kill the current president and his VP candidate, Geraldo Alckmin, and to imprison and murder Alexandre de Moraes - the High Court judge who has been overseeing his judicial proceedings.
The conspiracy was prevented because it couldn't obtain the endorsement of the military leaders. Lula was inaugurated without issue on January 1st, 2023.
But a seven days after, on January 8th, thousands of his followers invaded and destroyed government buildings in the national capital, Brazil's capital.
The law enforcement took action and around fifteen hundred individuals were taken into custody.
The judges found that the demonstrators had been provoked by the former president whose scheme, they said, was for the Brazilian military to intervene, restore order and bring him back to power.
At the moment, his attorneys called the over 27-year sentence unreasonably severe".
He was also prohibited from seeking elected position until 2060 - eight years after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a targeted investigation" and said it was designed to prevent him participating in the next presidential race.
