Jair Bolsonaro has been arrested after authorities concluded he posed a serious risk of fleeing while under home confinement.
The one-time leader was found guilty of plotting a government overthrow in the ninth month and given more than a 27-year term in incarceration, but he remained under home detention pending appeals.
Brazilian Supreme Court Justice the presiding justice said the move to detain the 70-year-old politician was a safety action after recent developments emerged.
This involved attempting to break his tracking device and a call for a public vigil that could "allow for a potential flight.
In a document approving the arrest, Justice Moraes said information from the facility tracking Bolsonaro's house arrest suggested the ex-president's plan to remove the surveillance device to guarantee victory in his getaway".
This, it said, would be assisted by the disorder caused by the protest called by his son.
His offspring, Flávio Bolsonaro, who serves as a legislator, called for a meeting of his followers near his father's house to take place on Saturday evening.
The senator wrote on online platforms on Friday: "Are you going to fight for your country, or see it all from your smartphone there on your sofa? I invite you to fight with us."
He said the vigil would be so followers could seek divine intervention for his well-being and for the reestablishment of democratic governance in our land."
Part of Justice Moraes's decision was the chance of his move to embassies near the home, considering that the investigations revealed a background of organizing to request asylum through a consular facility", a announcement said.
The judicial paperwork highlights that the American diplomatic mission in the federal district, the capital city, is positioned around approximately 13 kilometers from Bolsonaro's home.
The former president's legal troubles have generated frustration from fellow populist conservative American leader Trump, prompting him to enact a half-rate duty on imports of Brazilian goods.
The former president is being detained in a Federal Police station in the capital and will undergo a detention review on the following day.
It was only on Friday that the former president's lawyers asked the High Court to authorize him to complete his entire prison term under home confinement, with electronic monitoring.
They also asked that he be permitted to leave his home for healthcare, saying he required ongoing care for lung conditions and other illnesses.
The former president was found guilty of heading a conspiracy aimed at retaining his authority after he was defeated in the presidential race to his left-wing rival, President Lula.
Supreme Court justices said that he was aware of a plot which involved plans to murder Lula and his running partner, Alckmin, and to imprison and murder Alexandre de Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the endorsement of the military leaders. Lula was took office without issue on 1 January 2023.
But a week later, on the eighth of January, numerous his backers invaded and destroyed official structures in the national capital, the capital city.
The police intervened and around approximately 1,500 persons were detained.
The justices found that the rioters had been provoked by the former president whose strategy, they said, was for the country's army to intervene, reestablish control and bring him back to power.
At the time, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also barred from seeking elected position until the year 2060 - eight years after the completion of his term.
The ex-leader called the trial a political persecution and said it was aimed at blocking him participating in the next presidential race.
