Jair Bolsonaro has been detained after authorities found he posed a concrete flight risk while under domestic detention.
The ex-president was convicted of orchestrating a government overthrow in the ninth month and sentenced more than 27 years in jail, but he was staying under confinement pending appeals.
High Court Judge Justice Moraes said the move to detain the 70-year-old politician was a precautionary step after recent developments came to light.
This encompassed attempting to break his tracking device and a invitation to a public vigil that could enable a chance to flee".
Judicial Records Show Escape Concerns
In a filing authorising the arrest, the magistrate said data from the centre monitoring the former president's confinement suggested the ex-president's aim to disable the surveillance device to guarantee victory in his flight.
This, it said, would be assisted by the disorder caused by the demonstration called by his son.
His son, Flávio, who works as a congressional representative, called for a assembly of his supporters near his father's house to take place on Saturday evening.
His son wrote on online platforms on Friday: "Are you going to fight for your country, or observe everything from your smartphone there on your couch? I call on you to fight with us."
He said the demonstration would be so backers could offer prayers for his health and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of the magistrate's ruling was the possibility of his move to diplomatic missions near the home, considering that the probes revealed a history of planning to ask for protection through a embassy office", a announcement said.
The judicial paperwork highlights that the United States embassy in the national capital, Brazil's capital, is positioned around approximately 13 kilometers from his dwelling.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow right-wing populist United States President Trump, prompting him to impose a 50% tariff on Brazilian product imports.
He is being detained in a national police facility in the capital and will undergo a detention review on the next day.
Recent Legal Requests
It was only on Friday that the his legal team asked the Supreme Court to permit him to complete his entire prison term under house arrest, with tracking devices.
They also asked that he be permitted to depart his residence for medical treatment, saying he required ongoing care for respiratory ailments and other illnesses.
Details of Guilty Verdict
The former president was found guilty of leading a plot aimed at keeping him in power after he failed to win the presidential race to his left-wing rival, President Lula.
Supreme Court justices said that he had knowledge of a plot which included plans to kill the current president and his running partner, Geraldo Alckmin, and to imprison and murder the presiding judge - the High Court judge who has been managing the former president's case.
The scheme was stopped because it failed to get the backing of the military leaders. Lula was inaugurated without issue on January 1st, 2023.
But a seven days after, on the eighth of January, thousands of his followers attacked and damaged official structures in the national capital, Brasília.
The police took action and around approximately 1,500 persons were arrested.
The judges found that the protesters had been incited by the former president whose scheme, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the moment, his attorneys called the over 27-year sentence unreasonably severe".
He was also prohibited from running for public office until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The one-time head of state called the court case a targeted investigation" and said it was designed to prevent him competing in the 2026 national vote.
