Jair Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under home confinement.
The ex-president was sentenced of plotting a government overthrow in the ninth month and sentenced more than over two decades in incarceration, but he was staying under home detention pending court reviews.
High Court Judge Justice Moraes said the action to imprison the elderly politician was a preventative measure after "new facts" were revealed.
This encompassed attempting to break his ankle monitor and a invitation to a public vigil that could facilitate a chance to flee".
Court Filing Details Escape Concerns
In a document approving the custody, the judge said information from the centre monitoring Bolsonaro's house arrest suggested the ex-president's plan to remove the tracking monitor to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the demonstration called by his son.
His son, Flávio Bolsonaro, who holds office as a senator, called for a gathering of his followers near the former president's residence to take place on Saturday evening.
His son wrote on online platforms on Friday: "Are you going to fight for your homeland, or observe everything from your smartphone there on your sofa? I call on you to struggle with us."
He said the vigil would be so supporters could offer prayers for his health and for the restoration of democratic rule in our land."
Diplomatic Refuge Fears
Part of the judge's ruling was the potential of Bolsonaro's move to diplomatic missions near the dwelling, considering that the inquiries revealed a history of organizing to request asylum through a embassy office", a statement said.
The court filing emphasizes that the American diplomatic mission in the federal district, the capital city, is situated around approximately 13 kilometers from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President Trump, causing him to enact a half-rate duty on imports of Brazilian goods.
He is being kept in a federal law enforcement building in the capital and will undergo a detention review on Sunday.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the Supreme Court to allow him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that Bolsonaro be allowed to exit his dwelling for medical treatment, saying he demanded frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was determined responsible of heading a scheme aimed at retaining his authority after he was defeated in the national vote to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he was aware of a plot which involved plans to assassinate his opponent and his vice-presidential running mate, his vice-presidential candidate, and to detain and kill Alexandre de Moraes - the top judicial official who has been managing his judicial proceedings.
The conspiracy was thwarted because it couldn't obtain the endorsement of the armed forces officials. His successor was took office without incident on the first day of 2023.
But a following week, on 8 January, thousands of his backers stormed and vandalised government buildings in the national capital, Brazil's capital.
The security forces took action and around fifteen hundred individuals were taken into custody.
The magistrates found that the rioters had been incited by him whose scheme, they said, was for the country's army to take action, bring back stability and bring him back to power.
At the period, Bolsonaro's lawyers called the over 27-year sentence extremely harsh.
He was also banned from campaigning for office until 2060 - a decade minus two years after the completion of his term.
The ex-leader called the trial a "witch hunt and said it was designed to prevent him running in the 2026 national vote.
