Bolsonaro has been arrested after authorities concluded he posed a serious risk of fleeing while under domestic detention.
The ex-president was found guilty of planning a military coup in last fall and given more than a 27-year term in jail, but he remained under home detention pending appeals.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a safety action after fresh information were revealed.
This encompassed seeking to disable his ankle monitor and a invitation to a demonstration that could "allow for a chance to flee".
Legal Document Reveals Escape Risks
In a filing authorising the detention, Justice Moraes said intelligence from the centre monitoring the former president's confinement suggested the former leader's plan to remove the surveillance device to secure accomplishment in his escape.
This, it said, would be assisted by the disorder caused by the gathering called by his son.
His child, his son Flávio, who works as a senator, called for a meeting of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on social media on Friday: Will you battle for your homeland, or watch it all from your smartphone there on your couch? I invite you to struggle with us."
He said the demonstration would be so supporters could offer prayers for his health and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of the former president's move to foreign missions near the residence, considering that the inquiries revealed a record of arranging to request asylum through a embassy office", a statement said.
The legal document emphasizes that the US embassy in the capital, Brasilia, is positioned around 13km from his dwelling.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President Donald Trump, causing him to implement a 50% tariff on imports of Brazilian goods.
Bolsonaro is being detained in a national police facility in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the High Court to allow him to serve his whole jail sentence under house arrest, with digital surveillance.
They also asked that Bolsonaro be authorized to exit his dwelling for medical treatment, saying he needed frequent medical attention for respiratory ailments and other health problems.
Details of Guilty Verdict
He was convicted of leading a conspiracy aimed at retaining his authority after he lost the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plan which included plans to assassinate the current president and his VP candidate, Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The conspiracy was stopped because it didn't receive the endorsement of the military leaders. His successor was took office without incident on 1 January 2023.
But a seven days after, on January 8th, thousands of Bolsonaro supporters invaded and destroyed government buildings in the federal district, the capital city.
The security forces stepped in and around 1,500 people were arrested.
The judges found that the protesters had been incited by him whose strategy, they said, was for the Brazilian military to step in, reestablish control and bring him back to power.
At the moment, the legal team called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - a decade minus two years after the end of his sentence.
The ex-leader called the trial a targeted investigation" and said it was intended to stop him competing in the 2026 national vote.
