Jair Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of plotting a military coup in the ninth month and given more than 27 years in prison, but he was staying under confinement pending court reviews.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a precautionary step after recent developments came to light.
This encompassed trying to remove his tracking device and a invitation to a supporters' gathering that could "allow for a potential flight.
Judicial Records Show Escape Concerns
In a paperwork permitting the detention, the judge said data from the facility tracking his home detention suggested the ex-president's "intention to break the surveillance device to guarantee victory in his flight.
This, it said, would be assisted by the disorder caused by the protest called by his offspring.
His son, his son Flávio, who serves as a congressional representative, called for a gathering of his supporters near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on online platforms on the previous day: Do you plan to struggle for your homeland, or watch it all from your mobile device there on your couch? I call on you to fight with us."
He said the vigil would be so followers could "pray for his health and for the restoration of democratic rule in our country."
Embassy Asylum Concerns
Part of the magistrate's determination was the possibility of the former president's transfer to foreign missions near the dwelling, considering that the probes revealed a background of arranging to seek refuge through a diplomatic representation", a statement said.
The legal document underscores that the United States embassy in the federal district, Brasilia, is positioned around approximately 13 kilometers from Bolsonaro's home.
Worldwide Consequences
His judicial problems have provoked anger from fellow right-wing populist American leader Donald Trump, causing him to impose a 50% tariff on Brazilian product imports.
He is being kept in a federal law enforcement building in Brasilia and will undergo a detention review on Sunday.
Recent Judicial Appeals
It was only on last Friday that the his legal team asked the High Court to allow him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that the former president be authorized to depart his residence for medical care, saying he needed regular treatment for respiratory ailments and other illnesses.
Details of Guilty Verdict
Bolsonaro was convicted of leading a conspiracy aimed at keeping him in power after he was defeated in the 2022 election to his left-wing rival, President Lula.
High Court judges said that he knew of a scheme which involved plans to kill the current president and his VP candidate, Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been managing Bolsonaro's trial.
The conspiracy was prevented because it didn't receive the backing of the armed forces officials. The current president was inaugurated without problem on January 1st, 2023.
But a seven days after, on the eighth of January, many Bolsonaro supporters attacked and damaged public facilities in the national capital, Brazil's capital.
The police intervened and around approximately 1,500 persons were detained.
The judges found that the rioters had been provoked by Bolsonaro whose strategy, they said, was for the Brazilian military to intervene, bring back stability and return him to office.
At the time, the legal team called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until the year 2060 - eight years after the end of his sentence.
The former president called the court case a political persecution and said it was designed to prevent him participating in the 2026 presidential election.
