Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under domestic detention.
The former head of state was found guilty of plotting a armed takeover in September and handed more than 27 years in jail, but he continued under home detention pending legal challenges.
High Court Judge Alexandre de Moraes said the action to imprison 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 public vigil that could "allow for a potential flight.
Legal Document Reveals Escape Risks
In a filing authorising the custody, the magistrate said data from the centre monitoring his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the protest called by his offspring.
His son, Flávio Bolsonaro, who holds office as a congressional representative, called for a assembly of his backers near Bolsonaro's home to take place on Saturday night.
The senator wrote on social media on Friday: Will you battle for your homeland, or watch it all from your mobile device there on your settee? I invite you to struggle with us."
He said the gathering would be so supporters could "pray for his health and for the reestablishment of democratic governance in our country."
Embassy Asylum Concerns
Part of the judge's determination was the possibility of his move to foreign missions near the home, considering that the probes revealed a record of organizing to seek refuge through a embassy office", a declaration said.
The judicial paperwork underscores that the United States embassy in the national capital, the capital city, is positioned around approximately 13 kilometers from the former president's residence.
International Reactions
His judicial problems have drawn the ire of fellow conservative nationalist American leader Donald Trump, causing him to implement a half-rate duty on imports of Brazilian goods.
He is being held in a Federal Police station in Brasilia and will experience a imprisonment assessment on the next day.
Latest Court Petitions
It was only on Friday that the ex-leader's attorneys asked the Top Court to permit him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that Bolsonaro be allowed to leave his home for medical care, saying he demanded regular treatment for lung conditions and other health problems.
Details of Guilty Verdict
The former president was convicted of leading a conspiracy aimed at retaining his authority after he lost the presidential race to his left-wing rival, Lula.
Supreme Court justices said that he had knowledge of a scheme which involved plans to assassinate his opponent and his VP candidate, Alckmin, and to arrest and execute the presiding judge - the High Court judge who has been managing Bolsonaro's trial.
The conspiracy was stopped because it failed to get the backing of the armed forces officials. The current president was took office without issue on the first day of 2023.
But a week later, on the eighth of January, thousands of Bolsonaro supporters invaded and destroyed official structures in the capital, Brasília.
The police intervened and around fifteen hundred individuals were taken into custody.
The magistrates found that the rioters had been encouraged by the former president whose plan, they said, was for the Brazilian military to intervene, reestablish control and bring him back to power.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also banned from campaigning for office until the year 2060 - eight years after the end of his sentence.
The former president called the court case a targeted investigation" and said it was intended to stop him running in the 2026 national vote.
