Bolsonaro has been arrested after authorities determined he posed a definite escape threat while under home confinement.
The former head of state was found guilty of planning a government overthrow in the ninth month and given more than 27 years in jail, but he continued under house arrest pending court reviews.
Brazilian Supreme Court Justice Alexandre de Moraes said the move to detain the septuagenarian politician was a preventative measure after recent developments emerged.
This involved seeking to disable his tracking device and a call for a supporters' gathering that could enable a potential flight.
Judicial Records Show Escape Risks
In a filing authorising the custody, Justice Moraes said data from the facility tracking the former president's confinement suggested the ex-president's plan to remove the surveillance device to ensure success in his flight.
This, it said, would be made easier by the confusion caused by the protest called by his child.
His offspring, Flávio Bolsonaro, who works as a congressional representative, called for a assembly of his followers near his father's house to take place on Saturday night.
His son wrote on social media on the previous day: "Are you going to fight for your nation, or observe everything from your smartphone there on your settee? I invite you to fight with us."
He said the vigil would be so supporters could offer prayers for his well-being and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of Justice Moraes's ruling was the potential of Bolsonaro's move to diplomatic missions near the residence, considering that the probes revealed a history of planning to ask for protection through a embassy office", a announcement said.
The legal document emphasizes that the US embassy in the federal district, Brasilia, is located around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow populist conservative American leader Donald Trump, prompting him to impose a 50% tariff on Brazilian product imports.
He is being held in a federal law enforcement building in the capital and will undergo a custody hearing on the following day.
Recent Judicial Appeals
It was only on Friday that the his legal team asked the Supreme Court to permit him to complete his entire prison term under domestic detention, with tracking devices.
They also petitioned that he be permitted to exit his dwelling for medical treatment, saying he demanded ongoing care for respiratory ailments and other health problems.
Details of Guilty Verdict
He was found guilty of orchestrating a scheme aimed at keeping him in power after he was defeated in the national vote to his political opponent, Lula.
Supreme Court justices said that he knew of a plot which included plans to assassinate the current president and his VP candidate, his vice-presidential candidate, and to imprison and murder the presiding judge - the Supreme Court justice who has been presiding over the former president's case.
The scheme was thwarted because it failed to get the backing of the military leaders. His successor was took office without issue on 1 January 2023.
But a following week, on the eighth of January, thousands of his backers attacked and damaged government buildings in the capital, Brazil's capital.
The security forces took action and around 1,500 people were taken into custody.
The judges found that the protesters had been encouraged by him whose plan, they said, was for the national armed forces to intervene, bring back stability and reinstate his authority.
At the moment, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also banned from seeking elected position until 2060 - eight years after the completion of his term.
The ex-leader called the trial a "witch hunt and said it was aimed at blocking him running in the next presidential race.
