Jair Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under house arrest.
The ex-president was sentenced of planning a armed takeover in September and sentenced more than 27 years in incarceration, but he was staying under home detention pending legal challenges.
Top Judicial Official the presiding justice said the decision to arrest the elderly politician was a preventative measure after recent developments emerged.
This encompassed trying to remove his ankle monitor and a invitation to a supporters' gathering that could enable a chance to flee".
In a paperwork permitting the custody, the magistrate said intelligence from the unit overseeing his home detention suggested the former leader's plan to remove the surveillance device to ensure success in his getaway".
This, it said, would be assisted by the disorder caused by the demonstration called by his son.
His child, his son Flávio, who serves as a congressional representative, called for a meeting of his backers near Bolsonaro's home to take place on the weekend.
The senator wrote on online platforms on last Friday: Do you plan to struggle for your nation, or watch it all from your phone there on your sofa? I invite you to battle with us."
He said the gathering would be so followers could offer prayers for his well-being and for the return of democracy in our land."
Part of the magistrate's decision was the possibility of the former president's move to embassies near the home, considering that the probes revealed a history of planning to seek refuge through a embassy office", a statement said.
The legal document emphasizes that the American diplomatic mission in the capital, the capital city, is positioned around approximately 13 kilometers from his dwelling.
His judicial problems have provoked anger from fellow right-wing populist American leader Trump, prompting him to enact a half-rate duty on Brazilian product imports.
He is being kept in a federal law enforcement building in Brazil's capital city and will have a detention review on the following day.
It was only on the previous day that the ex-leader's attorneys asked the Top Court to authorize him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also requested that he be permitted to exit his dwelling for medical care, saying he demanded frequent medical attention for respiratory ailments and other ailments.
Bolsonaro was found guilty of orchestrating a conspiracy aimed at retaining his authority after he failed to win the national vote to his political opponent, President Lula.
Supreme Court justices said that he knew of a plan which encompassed plans to assassinate Lula and his VP candidate, his vice-presidential candidate, and to imprison and murder Justice Moraes - the High Court judge who has been overseeing the former president's case.
The plot was stopped because it failed to get the backing of the military leaders. The current president was inaugurated without problem on 1 January 2023.
But a week later, on the eighth of January, thousands of his backers stormed and vandalised government buildings in the capital, Brazil's capital.
The law enforcement took action and around approximately 1,500 persons were arrested.
The justices found that the rioters had been provoked by the former president whose plan, they said, was for the Brazilian military to intervene, restore order and reinstate his authority.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also prohibited from seeking elected position until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The former president called the legal proceedings a targeted investigation" and said it was intended to stop him participating in the 2026 presidential election.
