Bolsonaro has been taken into custody after authorities determined he posed a definite escape threat while under home confinement.
The one-time leader was found guilty of planning a government overthrow in the ninth month and sentenced more than over two decades in jail, but he remained under home detention pending appeals.
Top Judicial Official the presiding justice said the decision to arrest the 70-year-old politician was a precautionary step after fresh information were revealed.
This involved attempting to break his electronic bracelet and a call for a supporters' gathering that could "allow for a chance to flee".
Legal Document Reveals Escape Risks
In a document approving the detention, the judge said data from the facility tracking Bolsonaro's house arrest suggested the ex-president's aim to disable the tracking monitor to ensure success in his getaway".
This, it said, would be "facilitated by the confusion caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who serves as a congressional representative, called for a assembly of his backers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your country, or see it all from your mobile device there on your settee? I invite you to struggle with us."
He said the vigil would be so supporters could "pray for his physical condition and for the reestablishment of democratic governance in our nation."
Foreign Shelter Risks
Part of Justice Moraes's determination was the possibility of his "relocation to foreign missions near the home, considering that the inquiries revealed a history of arranging to ask for protection through a embassy office", a statement said.
The court filing underscores that the United States embassy in the federal district, Brazil's capital, is located around 8 miles from his dwelling.
International Reactions
Bolsonaro's legal woes have generated frustration from fellow populist conservative US President President Trump, leading him to impose a half-rate duty on Brazilian product imports.
He is being detained in a federal law enforcement building in the capital and will experience a imprisonment assessment on the next day.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the Top Court to allow him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that he be permitted to depart his residence for healthcare, saying he needed ongoing care for pulmonary infections and other health problems.
Background on Conviction
Bolsonaro was found guilty of orchestrating a conspiracy aimed at keeping him in power after he was defeated in the presidential race to his left-wing rival, President Lula.
Supreme Court justices said that he had knowledge of a scheme which encompassed plans to kill his opponent and his VP candidate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the High Court judge who has been managing his judicial proceedings.
The scheme was prevented because it didn't receive the backing of the armed forces officials. Lula was inaugurated without problem on January 1st, 2023.
But a week later, on the eighth of January, numerous his followers stormed and vandalised official structures in the capital, the capital city.
The security forces stepped in and around 1,500 people were arrested.
The justices found that the rioters had been encouraged by the former president whose plan, they said, was for the country's army to take action, reestablish control and return him to office.
At the moment, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also barred from seeking elected position until twenty-sixty - eight years later after the completion of his term.
The former president called the legal proceedings a "witch hunt and said it was aimed at blocking him participating in the 2026 national vote.
