Bolsonaro has been arrested after authorities determined he posed a definite escape threat while under home confinement.
The former head of state was found guilty of planning a armed takeover in the ninth month and sentenced more than a 27-year term in incarceration, but he was staying under house arrest pending legal challenges.
Top Judicial Official Alexandre de Moraes said the move to detain the septuagenarian politician was a precautionary step after "new facts" came to light.
This encompassed seeking to disable his electronic bracelet and a call for a supporters' gathering that could enable a potential flight.
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, the judge said data from the centre monitoring the former president's confinement suggested the ex-president's plan to remove the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be assisted by the chaos caused by the demonstration called by his offspring.
His offspring, Flávio Bolsonaro, who works as a legislator, called for a meeting of his backers near the former president's residence to take place on Saturday evening.
The senator wrote on digital networks on Friday: Do you plan to struggle for your nation, or see it all from your phone there on your sofa? I call on you to battle with us."
He said the demonstration would be so followers could "pray for his physical condition and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the possibility of his "relocation to diplomatic missions near the residence, considering that the probes revealed a background of organizing to ask for protection through a consular facility", a announcement said.
The legal document emphasizes that the US embassy in the capital, the capital city, is located around 8 miles from his dwelling.
International Reactions
The former president's legal troubles have provoked anger from fellow right-wing populist American leader Donald Trump, causing him to implement a fifty percent tax on Brazilian product imports.
The former president is being kept in a national police facility in the capital and will experience a custody hearing on Sunday.
Recent Judicial Appeals
It was only on Friday that the his legal team asked the Supreme Court to authorize him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that Bolsonaro be allowed to exit his dwelling for medical treatment, saying he demanded ongoing care for pulmonary infections and other health problems.
Context of Sentencing
He was convicted of heading a conspiracy aimed at retaining his authority after he was defeated in the presidential race to his ideological adversary, President Lula.
Supreme Court justices said that he knew of a plan which encompassed plans to assassinate his opponent and his VP candidate, his vice-presidential candidate, and to detain and kill Justice Moraes - the High Court judge who has been overseeing the former president's case.
The conspiracy was stopped because it failed to get the support of the armed forces officials. Lula was inaugurated without incident on January 1st, 2023.
But a following week, on the eighth of January, thousands of Bolsonaro supporters stormed and vandalised government buildings in the capital, the capital city.
The police took action and around fifteen hundred individuals were taken into custody.
The magistrates found that the demonstrators had been incited by him whose plan, they said, was for the national armed forces to step in, reestablish control and bring him back to power.
At the moment, Bolsonaro's lawyers called the over 27-year sentence extremely harsh.
He was also banned from campaigning for office until twenty-sixty - a decade minus two years after the conclusion of his imprisonment.
The former president called the legal proceedings a "witch hunt and said it was designed to prevent him running in the 2026 national vote.
