Jair Bolsonaro has been taken into custody after authorities determined he posed a definite escape threat while under domestic detention.
The one-time leader was convicted of orchestrating a military coup in the ninth month and handed more than 27 years in jail, but he remained under confinement pending legal challenges.
Top Judicial Official Alexandre de Moraes said the action to imprison the septuagenarian politician was a preventative measure after "new facts" came to light.
This included trying to remove his ankle monitor and a summons to a demonstration that could enable a potential flight.
In a filing authorising the custody, Justice Moraes said data from the centre monitoring the former president's confinement suggested the ex-president's plan to remove the electronic ankle bracelet to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the demonstration called by his offspring.
His offspring, Flávio Bolsonaro, who serves as a congressional representative, called for a meeting of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on social media on the previous day: Will you battle for your nation, or see it all from your smartphone there on your settee? I call on you to fight with us."
He said the gathering would be so backers could "pray for his physical condition and for the restoration of democratic rule in our country."
Part of the judge's determination was the chance of Bolsonaro's "relocation to embassies near the residence, considering that the inquiries revealed a record of planning to ask for protection through a consular facility", a announcement said.
The judicial paperwork emphasizes that the United States embassy in the capital, the capital city, is positioned around approximately 13 kilometers from Bolsonaro's home.
The former president's legal troubles have drawn the ire of fellow conservative nationalist United States President Donald Trump, prompting him to impose a half-rate duty on goods coming from Brazil.
The former president is being detained in a Federal Police station in Brazil's capital city and will experience a imprisonment assessment on Sunday.
It was only on last Friday that the ex-leader's attorneys asked the Top Court to permit him to complete his entire prison term under house arrest, with electronic monitoring.
They also requested that he be authorized to depart his residence for healthcare, saying he needed frequent medical attention for respiratory ailments and other health problems.
He was determined responsible of orchestrating a conspiracy aimed at keeping him in power after he failed to win the presidential race to his political opponent, Lula.
High Court judges said that he was aware of a plan which encompassed plans to murder the current president and his running partner, Geraldo Alckmin, and to detain and kill Justice Moraes - the High Court judge who has been managing his judicial proceedings.
The plot was prevented because it couldn't obtain the endorsement of the army and air force commanders. His successor was inaugurated without problem on January 1st, 2023.
But a following week, on the eighth of January, thousands of his backers stormed and vandalised government buildings in the federal district, Brazil's capital.
The law enforcement stepped in and around fifteen hundred individuals were arrested.
The judges found that the rioters had been incited by the former president whose scheme, they said, was for the national armed forces to step in, bring back stability and reinstate his authority.
At the period, his attorneys called the 27 years and three months sentence extremely harsh.
He was also banned from seeking elected position until twenty-sixty - eight years after the completion of his term.
The ex-leader called the trial a targeted investigation" and said it was intended to stop him competing in the next presidential race.
