Jair Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under home confinement.
The ex-president was found guilty of planning a government overthrow in last fall and given more than over two decades in jail, but he remained under confinement pending appeals.
High Court Judge the presiding justice said the move to detain the septuagenarian politician was a safety action after fresh information came to light.
This encompassed seeking to disable his electronic bracelet and a summons to a supporters' gathering that could "allow for a chance to flee".
Court Filing Details Flight Fears
In a document approving the detention, the judge said information from the facility tracking the former president's confinement suggested the former leader's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be "facilitated by the chaos caused by the demonstration called by his offspring.
His son, his son Flávio, who holds office as a legislator, called for a meeting of his followers near his father's house to take place on Saturday night.
The senator wrote on digital networks on the previous day: "Are you going to fight for your country, or observe everything from your mobile device there on your settee? I invite you to battle with us."
He said the vigil would be so followers could offer prayers for his physical condition and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the chance of Bolsonaro's transfer to diplomatic missions near the home, considering that the investigations revealed a background of planning to ask for protection through a embassy office", a announcement said.
The judicial paperwork emphasizes that the US embassy in the capital, Brazil's capital, is positioned around 13km from his dwelling.
International Reactions
Bolsonaro's legal woes have provoked anger from fellow right-wing populist United States President Donald Trump, leading him to implement a 50% tariff on imports of Brazilian goods.
Bolsonaro is being kept in a federal law enforcement building in the capital and will undergo a imprisonment assessment on the next day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also petitioned that the former president be authorized to exit his dwelling for medical treatment, saying he required regular treatment for pulmonary infections and other ailments.
Details of Guilty Verdict
The former president was found guilty of heading a conspiracy aimed at maintaining his control after he failed to win the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he was aware of a plan which included plans to murder Lula and his VP candidate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been presiding over the former president's case.
The scheme was prevented because it didn't receive the backing of the army and air force commanders. His successor was sworn in without problem on January 1st, 2023.
But a week later, on the eighth of January, thousands of Bolsonaro supporters attacked and damaged government buildings in the capital, Brasília.
The security forces took action and around 1,500 people were arrested.
The justices found that the rioters had been provoked by him whose strategy, they said, was for the Brazilian military to take action, reestablish control and return him to office.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence unreasonably severe".
He was also barred from seeking elected position until twenty-sixty - eight years later after the end of his sentence.
The one-time head of state called the legal proceedings a "witch hunt and said it was aimed at blocking him participating in the next presidential race.
