Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under home confinement.
The former head of state was sentenced of plotting a military coup in last fall and sentenced more than a 27-year term in prison, but he continued under house arrest pending legal challenges.
Top Judicial Official Justice Moraes said the decision to arrest the septuagenarian politician was a preventative measure after fresh information came to light.
This involved seeking to disable his ankle monitor and a summons to a public vigil that could facilitate a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, Justice Moraes said information from the unit overseeing the former president's confinement suggested the ex-president's plan to remove the tracking monitor to secure accomplishment in his flight.
This, it said, would be "facilitated by the chaos caused by the gathering called by his child.
His child, Flávio, who works as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
His son wrote on digital networks on last Friday: Do you plan to struggle for your country, or see it all from your smartphone there on your settee? I invite you to struggle with us."
He said the gathering would be so backers could offer prayers for his physical condition and for the reestablishment of democratic governance in our country."
Diplomatic Refuge Fears
Part of the judge's determination was the potential of his move to foreign missions near the dwelling, considering that the probes revealed a history of arranging to ask for protection through a diplomatic representation", a announcement said.
The judicial paperwork underscores that the US embassy in the capital, Brasilia, is situated around 13km from the former president's residence.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow populist conservative American leader Donald Trump, causing him to enact a fifty percent tax on goods coming from Brazil.
The former president is being detained in a federal law enforcement building in Brasilia and will undergo a imprisonment assessment on the next day.
Latest Court Petitions
It was only on last Friday that the former president's lawyers asked the High Court to permit him to serve his whole jail sentence under house arrest, with tracking devices.
They also asked that Bolsonaro be permitted to depart his residence for medical care, saying he required regular treatment for pulmonary infections and other health problems.
Details of Guilty Verdict
Bolsonaro was found guilty of leading a scheme aimed at maintaining his control after he was defeated in the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a plan which encompassed plans to kill Lula and his VP candidate, Geraldo Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been presiding over his judicial proceedings.
The conspiracy was thwarted because it failed to get the backing of the military leaders. His successor was inaugurated without incident on January 1st, 2023.
But a week later, on the eighth of January, thousands of Bolsonaro supporters stormed and vandalised official structures in the federal district, Brasília.
The security forces took action and around 1,500 people were detained.
The justices found that the demonstrators had been encouraged by him whose scheme, they said, was for the national armed forces to step in, bring back stability and return him to office.
At the period, Bolsonaro's lawyers called the decades-long sentence extremely harsh.
He was also banned from running for public office until twenty-sixty - a decade minus two years after the end of his sentence.
The former president called the trial a targeted investigation" and said it was aimed at blocking him competing in the 2026 presidential election.
