Bolsonaro has been detained after authorities determined he posed a definite escape threat while under house arrest.
The one-time leader was sentenced of plotting a armed takeover in last fall and sentenced more than a 27-year term in incarceration, but he continued under house arrest pending legal challenges.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the elderly politician was a precautionary step after fresh information came to light.
This encompassed attempting to break his tracking device and a call for a demonstration that could "allow for a potential flight.
Judicial Records Show Flight Fears
In a filing authorising the arrest, Justice Moraes said data from the facility tracking the former president's confinement suggested the ex-president's "intention to break the surveillance device to guarantee victory in his getaway".
This, it said, would be made easier by the chaos caused by the gathering called by his son.
His child, Flávio Bolsonaro, who holds office as a legislator, called for a meeting of his followers near the former president's residence to take place on the weekend.
His son wrote on digital networks on last Friday: Will you battle for your country, or see it all from your mobile device there on your couch? I invite you to struggle with us."
He said the demonstration would be so followers could seek divine intervention for his health and for the return of democracy in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the potential of the former president's move to diplomatic missions near the dwelling, considering that the investigations revealed a history of arranging to ask for protection through a embassy office", a announcement said.
The judicial paperwork underscores that the US embassy in the federal district, the capital city, is situated around 13km from Bolsonaro's home.
Global Responses
His judicial problems have provoked anger from fellow populist conservative United States President Donald Trump, prompting him to impose a fifty percent tax on goods coming from Brazil.
The former president is being detained in a federal law enforcement building in the capital and will undergo a detention review on Sunday.
Latest Court Petitions
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to allow him to fulfill his full incarceration period under domestic detention, with tracking devices.
They also petitioned that the former president be allowed to leave his home for medical treatment, saying he needed frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a scheme aimed at retaining his authority after he was defeated in the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a plan which involved plans to murder Lula and his VP candidate, Geraldo Alckmin, and to imprison and murder Justice Moraes - the High Court judge who has been presiding over Bolsonaro's trial.
The scheme was prevented because it failed to get the support of the military leaders. His successor was sworn in without incident on January 1st, 2023.
But a seven days after, on the eighth of January, thousands of his followers invaded and destroyed public facilities in the capital, Brazil's capital.
The security forces stepped in and around fifteen hundred individuals were detained.
The magistrates found that the protesters had been provoked by Bolsonaro whose plan, they said, was for the country's army to intervene, bring back stability and bring him back to power.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also banned from campaigning for office until twenty-sixty - eight years later after the end of his sentence.
The former president called the trial a targeted investigation" and said it was aimed at blocking him participating in the 2026 national vote.
