Bolsonaro has been taken into custody after authorities found he posed a definite escape threat while under home confinement.
The one-time leader was found guilty of orchestrating a armed takeover in last fall and sentenced more than over two decades in jail, but he was staying under confinement pending appeals.
High Court Judge Justice Moraes said the action to imprison the septuagenarian politician was a preventative measure after fresh information came to light.
This included seeking to disable his electronic bracelet and a summons to a demonstration that could "allow for a potential flight.
Judicial Records Show Escape Concerns
In a filing authorising the detention, the judge said intelligence from the facility tracking the former president's confinement suggested the one-time head of state's "intention to break the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be "facilitated by the disorder caused by the protest called by his child.
His child, Flávio, who works as a legislator, called for a assembly of his followers near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Will you battle for your homeland, or watch it all from your smartphone there on your couch? I call on you to struggle with us."
He said the gathering would be so backers could offer prayers for his health and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the chance of Bolsonaro's transfer to diplomatic missions near the dwelling, considering that the probes revealed a history of arranging to ask for protection through a embassy office", a statement said.
The court filing emphasizes that the American diplomatic mission in the capital, Brasilia, is positioned around 13km from the former president's residence.
Global Responses
His judicial problems have generated frustration from fellow populist conservative US President Donald Trump, causing him to impose a fifty percent tax on goods coming from Brazil.
Bolsonaro is being held in a Federal Police station in the capital and will undergo a detention review on the following day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the Top Court to allow him to serve his whole jail sentence under home confinement, with electronic monitoring.
They also requested that he be authorized to depart his residence for healthcare, saying he required frequent medical attention for respiratory ailments and other ailments.
Background on Conviction
Bolsonaro was determined responsible of orchestrating a plot aimed at keeping him in power 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 included plans to kill Lula and his running partner, Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been overseeing Bolsonaro's trial.
The scheme was stopped because it didn't receive the endorsement of the army and air force commanders. The current president was inaugurated without problem on January 1st, 2023.
But a seven days after, on the eighth of January, numerous Bolsonaro supporters invaded and destroyed government buildings in the federal district, Brazil's capital.
The police intervened and around 1,500 people were arrested.
The justices found that the rioters had been encouraged by Bolsonaro whose scheme, they said, was for the Brazilian military to take action, bring back stability and return him to office.
At the moment, the legal team called the decades-long sentence extremely harsh.
He was also prohibited from running for public office until twenty-sixty - a decade minus two years after the end of his sentence.
The one-time head of state called the court case a "witch hunt and said it was intended to stop him running in the 2026 presidential election.
