The former Brazilian leader has been taken into custody after authorities concluded he posed a definite escape threat while under domestic detention.
The ex-president was found guilty of plotting a government overthrow in September and given more than over two decades in jail, but he remained under house arrest pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the 70-year-old politician was a preventative measure after fresh information came to light.
This included attempting to break his ankle monitor and a summons to a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Escape Risks
In a paperwork permitting the detention, the judge said information from the centre monitoring the former president's confinement suggested the former leader's plan to remove the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be "facilitated by the chaos caused by the demonstration called by his child.
His offspring, Flávio, who serves as a legislator, called for a assembly of his followers near the former president's residence to take place on Saturday evening.
The senator wrote on social media on the previous day: "Are you going to fight for your nation, or watch it all from your phone there on your sofa? I invite you to struggle with us."
He said the vigil would be so supporters could offer prayers for his physical condition and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of Justice Moraes's determination was the possibility of Bolsonaro's move to foreign missions near the dwelling, considering that the investigations revealed a background of planning to request asylum through a consular facility", a announcement said.
The court filing emphasizes that the US embassy in the national capital, the capital city, is positioned around 13km from the former president's residence.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist US President President Trump, leading him to impose a half-rate duty on imports of Brazilian goods.
He is being kept in a federal law enforcement building in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the High Court to allow him to serve his whole jail sentence under home confinement, with electronic monitoring.
They also petitioned that he be allowed to leave his home for medical treatment, saying he required regular treatment for lung conditions and other health problems.
Details of Guilty Verdict
He was convicted of heading a plot aimed at keeping him in power after he was defeated in the national vote to his ideological adversary, President Lula.
Supreme Court justices said that he had knowledge of a plot which included plans to murder the current president and his VP candidate, his vice-presidential candidate, and to detain and kill Justice Moraes - the High Court judge who has been managing the former president's case.
The scheme was stopped because it failed to get the endorsement of the armed forces officials. Lula was inaugurated without problem on the first day of 2023.
But a week later, on January 8th, many his backers attacked and damaged official structures in the capital, Brazil's capital.
The security forces intervened and around 1,500 people were detained.
The justices found that the rioters had been provoked by Bolsonaro whose plan, they said, was for the national armed forces to step in, reestablish control and reinstate his authority.
At the moment, his attorneys called the decades-long sentence unreasonably severe".
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 trial a political persecution and said it was designed to prevent him competing in the 2026 presidential election.
