Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under house arrest.
The ex-president was convicted of planning a military coup in the ninth month and handed more than over two decades in incarceration, but he remained under house arrest pending appeals.
High Court Judge the presiding justice said the action to imprison the elderly politician was a preventative measure after recent developments were revealed.
This encompassed attempting to break his electronic bracelet and a invitation to a demonstration that could enable a potential flight.
Court Filing Details Escape Concerns
In a document approving the custody, Justice Moraes said data from the facility tracking the former president's confinement suggested the former leader's aim to disable the tracking monitor to guarantee victory in his flight.
This, it said, would be assisted by the chaos caused by the protest called by his child.
His son, Flávio, who serves as a congressional representative, called for a assembly of his supporters near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your country, or watch it all from your smartphone there on your settee? I invite you to battle with us."
He said the gathering would be so supporters could "pray for his health and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of the judge's decision was the possibility of Bolsonaro's transfer to diplomatic missions near the dwelling, considering that the inquiries revealed a background of arranging to ask for protection through a consular facility", a declaration said.
The legal document emphasizes that the American diplomatic mission in the federal district, the capital city, is situated around 13km from his dwelling.
International Reactions
The former president's legal troubles have drawn the ire of fellow right-wing populist United States President President Trump, leading him to implement 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 have a detention review on the next day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the High Court to permit him to complete his entire prison term under domestic detention, with tracking devices.
They also requested that he be allowed to depart his residence for medical treatment, saying he required frequent medical attention for respiratory ailments and other illnesses.
Context of Sentencing
Bolsonaro was found guilty of heading a plot aimed at maintaining his control after he lost the national vote to his ideological adversary, President Lula.
High Court judges said that he knew of a plot which encompassed plans to assassinate Lula and his vice-presidential running mate, his vice-presidential candidate, and to detain and kill the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The scheme was thwarted because it didn't receive the endorsement of the army and air force commanders. Lula was inaugurated without problem on 1 January 2023.
But a week later, on the eighth of January, many his followers stormed and vandalised official structures in the national capital, the capital city.
The law enforcement stepped in and around approximately 1,500 persons were detained.
The judges found that the protesters had been provoked by the former president whose scheme, they said, was for the Brazilian military to step in, restore order and reinstate his authority.
At the moment, his attorneys called the over 27-year sentence "absurdly excessive.
He was also prohibited from seeking elected position until the year 2060 - eight years after the conclusion of his imprisonment.
The ex-leader called the trial a targeted investigation" and said it was intended to stop him running in the 2026 national vote.
