Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under domestic detention.
The former head of state was sentenced of plotting a government overthrow in September and handed more than a 27-year term in incarceration, but he remained under house arrest pending court reviews.
High Court Judge the presiding justice said the move to detain the 70-year-old politician was a safety action after recent developments emerged.
This encompassed attempting to break his tracking device and a invitation to a public vigil that could facilitate a potential flight.
Judicial Records Show Flight Fears
In a document approving the custody, the magistrate said intelligence from the centre monitoring Bolsonaro's house arrest suggested the former leader's "intention to break the tracking monitor to secure accomplishment in his flight.
This, it said, would be assisted by the confusion caused by the protest called by his offspring.
His child, Flávio, who works as a legislator, called for a assembly of his backers near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on digital networks on last Friday: Do you plan to struggle for your homeland, or observe everything from your smartphone there on your sofa? I invite you to struggle with us."
He said the vigil would be so backers could seek divine intervention for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the magistrate's decision was the chance of his transfer to diplomatic missions near the home, considering that the investigations revealed a background of planning to seek refuge through a consular facility", a statement said.
The legal document emphasizes that the American diplomatic mission in the federal district, Brasilia, is positioned around 8 miles from the former president's residence.
Global Responses
His judicial problems have provoked anger from fellow right-wing populist US President President Trump, causing him to enact a 50% tariff on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brazil's capital city and will have a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on Friday that the former president's lawyers asked the High Court to allow him to serve his whole jail sentence under house arrest, with digital surveillance.
They also petitioned that he be permitted to exit his dwelling for medical care, saying he demanded frequent medical attention for respiratory ailments and other ailments.
Background on Conviction
He was determined responsible of leading a conspiracy aimed at retaining his authority after he failed to win the national vote to his ideological adversary, Lula.
Supreme Court justices said that he was aware of a plan which involved plans to murder the current president and his running partner, his vice-presidential candidate, and to arrest and execute the presiding judge - the High Court judge who has been managing the former president's case.
The plot was prevented because it failed to get the endorsement of the military leaders. The current president was took office without incident on January 1st, 2023.
But a week later, on 8 January, thousands of Bolsonaro supporters invaded and destroyed government buildings in the federal district, the capital city.
The police stepped in and around fifteen hundred individuals were taken into custody.
The judges found that the protesters had been encouraged by him whose plan, they said, was for the national armed forces to step in, bring back stability and bring him back to power.
At the time, the legal team called the over 27-year sentence extremely harsh.
He was also prohibited from seeking elected position until 2060 - a decade minus two years after the completion of his term.
The former president called the court case a political persecution and said it was aimed at blocking him running in the 2026 presidential election.
