Jair Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under house arrest.
The one-time leader was found guilty of planning a armed takeover in the ninth month and given more than a 27-year term in incarceration, but he continued under house arrest pending appeals.
Top Judicial Official Alexandre de Moraes said the action to imprison the 70-year-old politician was a preventative measure after "new facts" came to light.
This involved attempting to break his ankle monitor and a invitation to a demonstration that could "allow for a potential flight.
Legal Document Reveals Flight Fears
In a filing authorising the custody, Justice Moraes said data from the facility tracking Bolsonaro's house arrest suggested the ex-president's aim to disable the tracking monitor to secure accomplishment in his escape.
This, it said, would be made easier by the chaos caused by the protest called by his child.
His child, Flávio, who holds office as a senator, called for a gathering of his followers near the former president's residence to take place on the weekend.
His son wrote on digital networks on last Friday: "Are you going to fight for your homeland, or observe everything from your mobile device there on your settee? I invite you to battle with us."
He said the demonstration would be so supporters could offer prayers for his health and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of Justice Moraes's determination was the possibility of his transfer to foreign missions near the home, considering that the investigations revealed a background of planning to ask for protection through a consular facility", a announcement said.
The judicial paperwork underscores that the US embassy in the federal district, Brasilia, is positioned around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
His judicial problems have drawn the ire of fellow conservative nationalist United States President Trump, leading him to enact a 50% tariff on imports of Brazilian goods.
Bolsonaro is being detained in a Federal Police station in the capital and will experience a custody hearing on the following day.
Recent Judicial Appeals
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to allow him to fulfill his full incarceration period under house arrest, with tracking devices.
They also petitioned that he be permitted to leave his home for medical treatment, saying he needed frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
The former president was convicted of heading a conspiracy aimed at retaining his authority after he failed to win the presidential race to his political opponent, President Lula.
High Court judges said that he had knowledge of a plan which encompassed plans to assassinate the current president and his VP candidate, his vice-presidential candidate, and to arrest and execute the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The scheme was thwarted because it couldn't obtain the support of the army and air force commanders. The current president was sworn in without problem on 1 January 2023.
But a seven days after, on 8 January, many his followers attacked and damaged official structures in the federal district, Brazil's capital.
The police took action and around approximately 1,500 persons were arrested.
The magistrates found that the rioters had been provoked by the former president whose scheme, they said, was for the national armed forces to intervene, reestablish control and bring him back to power.
At the period, the legal team called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the court case a targeted investigation" and said it was intended to stop him competing in the 2026 national vote.
