The former Brazilian leader has been arrested after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of plotting a military coup in the ninth month and given more than 27 years in prison, but he continued under confinement pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the 70-year-old politician was a preventative measure after fresh information emerged.
This involved seeking to disable his ankle monitor and a invitation to a public vigil that could "allow for a chance to flee".
Judicial Records Show Escape Risks
In a filing authorising the custody, Justice Moraes said data from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state'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 demonstration called by his son.
His child, his son Flávio, who serves as a senator, called for a assembly of his backers near the former president's residence to take place on the weekend.
His son wrote on social media on Friday: Do you plan to struggle for your homeland, or watch it all from your phone there on your sofa? I urge you to fight with us."
He said the vigil would be so backers could seek divine intervention for his physical condition and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of the magistrate's decision was the potential of Bolsonaro's move to diplomatic missions near the residence, considering that the investigations revealed a background of organizing to ask for protection through a embassy office", a announcement said.
The court filing emphasizes that the US embassy in the capital, Brazil's capital, is situated around 13km from the former president's residence.
Global Responses
His judicial problems have generated frustration from fellow right-wing populist United States President Trump, prompting him to implement a fifty percent tax on goods coming from Brazil.
He is being held in a national police facility in the capital and will have a detention review on Sunday.
Recent Legal Requests
It was only on the previous day that the his legal team asked the Top Court to permit him to complete his entire prison term under house arrest, with tracking devices.
They also requested that Bolsonaro be authorized to leave his home for medical care, saying he demanded ongoing care for respiratory ailments and other illnesses.
Details of Guilty Verdict
He was determined responsible of heading a scheme aimed at keeping him in power after he failed to win the national vote to his political opponent, President Lula.
High Court judges said that he was aware of a scheme which encompassed plans to kill the current president and his running partner, Geraldo Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The conspiracy was thwarted because it couldn't obtain the endorsement of the armed forces officials. Lula was took office without incident on the first day of 2023.
But a week later, on the eighth of January, many his backers stormed and vandalised government buildings in the federal district, Brazil's capital.
The security forces took action and around approximately 1,500 persons were arrested.
The magistrates found that the rioters had been encouraged by the former president whose strategy, they said, was for the national armed forces to step in, reestablish control and bring him back to power.
At the time, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also prohibited from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the trial a targeted investigation" and said it was designed to prevent him competing in the 2026 presidential election.
