Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under domestic detention.
The former head of state was found guilty of plotting a military coup in the ninth month and given more than a 27-year term in jail, but he remained under confinement pending legal challenges.
Top Judicial Official Justice Moraes said the decision to arrest the septuagenarian politician was a preventative measure after "new facts" were revealed.
This encompassed seeking to disable his electronic bracelet and a invitation to a public vigil that could facilitate a chance to flee".
Court Filing Details Flight Fears
In a filing authorising the custody, the magistrate said data from the facility tracking Bolsonaro's house arrest suggested the ex-president's aim to disable the surveillance device to secure accomplishment in his flight.
This, it said, would be made easier by the chaos caused by the protest called by his child.
His offspring, his son Flávio, who holds office as a legislator, called for a meeting of his followers near the former president's residence to take place on Saturday evening.
The senator wrote on online platforms on Friday: "Are you going to fight for your homeland, or observe everything from your phone there on your sofa? I urge you to struggle with us."
He said the gathering would be so backers could seek divine intervention for his health and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of the judge's ruling was the potential of the former president's transfer to embassies near the dwelling, considering that the inquiries revealed a background of planning to seek refuge through a embassy office", a declaration said.
The legal document underscores that the US embassy in the capital, Brasilia, is located around approximately 13 kilometers from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have provoked anger from fellow populist conservative American leader President Trump, prompting him to implement a fifty percent tax on imports of Brazilian goods.
He is being held in a federal law enforcement building in Brazil's capital city and will undergo a detention review on the following day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the Supreme Court to allow him to complete his entire prison term under house arrest, with tracking devices.
They also petitioned that Bolsonaro be allowed to exit his dwelling for healthcare, saying he demanded regular treatment for lung conditions and other ailments.
Details of Guilty Verdict
Bolsonaro was convicted of heading a scheme aimed at maintaining his control after he was defeated in the presidential race to his political opponent, Lula.
Supreme Court justices said that he had knowledge of a plot which included plans to assassinate Lula and his VP candidate, his vice-presidential candidate, and to imprison and murder Justice Moraes - the top judicial official who has been presiding over his judicial proceedings.
The scheme was prevented because it failed to get the endorsement of the military leaders. The current president was sworn in without incident on January 1st, 2023.
But a following week, on the eighth of January, thousands of his followers stormed and vandalised official structures in the national capital, Brasília.
The law enforcement took action and around fifteen hundred individuals were detained.
The judges found that the protesters had been provoked by Bolsonaro whose scheme, they said, was for the Brazilian military to take action, restore order and return him to office.
At the period, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a "witch hunt and said it was intended to stop him competing in the 2026 national vote.
