Bolsonaro has been arrested after authorities found he posed a serious risk of fleeing while under domestic detention.
The former head of state was found guilty of orchestrating a government overthrow in last fall and handed more than over two decades in incarceration, but he was staying under confinement pending court reviews.
High Court Judge the presiding justice said the decision to arrest the elderly politician was a preventative measure after "new facts" came to light.
This encompassed trying to remove his electronic bracelet and a summons to a public vigil that could "allow for a possible escape.
Judicial Records Show Escape Risks
In a filing authorising the detention, the magistrate said intelligence from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's "intention to break 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 offspring.
His offspring, his son Flávio, who serves as a congressional representative, called for a meeting of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on Friday: "Are you going to fight for your homeland, or see it all from your phone there on your sofa? I invite you to fight with us."
He said the vigil would be so supporters could "pray for his well-being and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the judge's determination was the potential of Bolsonaro's transfer to foreign missions near the dwelling, considering that the probes revealed a record of organizing to seek refuge through a consular facility", a statement said.
The court filing emphasizes that the American diplomatic mission in the capital, Brazil's capital, is situated around approximately 13 kilometers from the former president's residence.
International Reactions
His judicial problems have generated frustration from fellow right-wing populist US President Donald Trump, prompting him to implement a half-rate duty on Brazilian product imports.
He is being kept in a national police facility in Brasilia and will undergo a imprisonment assessment on the following day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the High Court to authorize him to complete his entire prison term under domestic detention, with electronic monitoring.
They also requested that he be allowed to leave his home for healthcare, saying he required frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
He was found guilty of heading a conspiracy aimed at maintaining his control after he failed to win 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 his opponent and his VP candidate, his vice-presidential candidate, and to detain and kill Justice Moraes - the top judicial official who has been managing the former president's case.
The conspiracy was stopped because it couldn't obtain the endorsement of the military leaders. Lula was took office without issue on the first day of 2023.
But a seven days after, on January 8th, thousands of Bolsonaro supporters invaded and destroyed official structures in the federal district, Brazil's capital.
The security forces intervened and around fifteen hundred individuals were taken into custody.
The justices found that the protesters had been provoked by Bolsonaro whose plan, they said, was for the country's army to take action, reestablish control and return him to office.
At the time, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until 2060 - eight years after the conclusion of his imprisonment.
The ex-leader called the legal proceedings a targeted investigation" and said it was designed to prevent him competing in the next presidential race.
