Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was found guilty of orchestrating a armed takeover in the ninth month and sentenced more than over two decades in prison, but he was staying under confinement pending legal challenges.
High Court Judge Justice Moraes said the decision to arrest the septuagenarian politician was a preventative measure after fresh information were revealed.
This involved seeking to disable his tracking device and a call for a supporters' gathering that could facilitate a potential flight.
Court Filing Details Escape Risks
In a filing authorising the detention, the judge said data from the unit overseeing his home detention suggested the former leader's plan to remove the tracking monitor to guarantee victory in his getaway".
This, it said, would be "facilitated by the chaos caused by the protest called by his child.
His child, Flávio Bolsonaro, who serves as a senator, called for a meeting of his supporters near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on the previous day: Will you battle for your homeland, or observe everything from your mobile device there on your sofa? I invite you to fight with us."
He said the vigil would be so supporters could offer prayers for his health and for the return of democracy in our land."
Foreign Shelter Risks
Part of the magistrate's decision was the chance of his move to foreign missions near the home, considering that the inquiries revealed a record of organizing to ask for protection through a consular facility", a declaration said.
The court filing emphasizes that the United States embassy in the national capital, the capital city, is located around 13km from the former president's residence.
Global Responses
His judicial problems have generated frustration from fellow conservative nationalist American leader Trump, prompting him to implement a fifty percent tax on goods coming from Brazil.
Bolsonaro is being kept in a federal law enforcement building in Brasilia and will undergo a custody hearing on Sunday.
Recent Legal Requests
It was only on last Friday that the ex-leader's attorneys asked the Top Court to permit him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also requested that he be authorized to exit his dwelling for medical care, saying he demanded ongoing care for pulmonary infections and other ailments.
Context of Sentencing
The former president was found guilty of heading a plot aimed at retaining his authority after he failed to win the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he knew of a plan which involved plans to kill the current president and his VP candidate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been managing his judicial proceedings.
The conspiracy was thwarted because it failed to get the endorsement of the army and air force commanders. The current president was sworn in without issue on 1 January 2023.
But a following week, on the eighth of January, thousands of Bolsonaro supporters invaded and destroyed government buildings in the national capital, Brasília.
The law enforcement intervened and around 1,500 people were detained.
The justices found that the rioters had been provoked by Bolsonaro whose scheme, they said, was for the national armed forces to step in, restore order and bring him back to power.
At the moment, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - eight years after the end of his sentence.
The one-time head of state called the trial a targeted investigation" and said it was aimed at blocking him running in the 2026 national vote.
