Bolsonaro has been taken into custody after authorities found he posed a definite escape threat while under house arrest.
The ex-president was sentenced of orchestrating a government overthrow in the ninth month and given more than 27 years in jail, but he was staying under home detention pending appeals.
High Court Judge Alexandre de Moraes said the move to detain the 70-year-old politician was a safety action after fresh information were revealed.
This encompassed attempting to break his electronic bracelet and a call for a demonstration that could facilitate a possible escape.
Court Filing Details Escape Concerns
In a filing authorising the custody, the judge said data from the facility tracking the former president's confinement suggested the one-time head of state's plan to remove the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be "facilitated by the confusion caused by the protest called by his offspring.
His offspring, his son Flávio, who serves as a legislator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on last Friday: "Are you going to fight for your country, or observe everything from your phone there on your couch? I invite you to fight with us."
He said the demonstration would be so supporters could "pray for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the chance of his move to diplomatic missions near the home, considering that the probes revealed a history of arranging to seek refuge through a embassy office", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the federal district, the capital city, is positioned around 13km from the former president's residence.
Worldwide Consequences
His judicial problems have provoked anger from fellow populist conservative United States President Trump, leading him to impose a half-rate duty on goods coming from Brazil.
The former president is being detained in a federal law enforcement building in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on the previous day that the ex-leader's attorneys asked the High Court to authorize him to complete his entire prison term under home confinement, with digital surveillance.
They also asked that he be permitted to leave his home for medical treatment, saying he needed frequent medical attention for pulmonary infections and other health problems.
Background on Conviction
The former president was convicted of leading a scheme aimed at retaining his authority after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a plan which encompassed plans to assassinate the current president and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Alexandre de Moraes - the High Court judge who has been managing Bolsonaro's trial.
The scheme was thwarted because it failed to get the backing of the army and air force commanders. His successor was took office without incident on January 1st, 2023.
But a seven days after, on January 8th, numerous his backers stormed and vandalised official structures in the capital, the capital city.
The police intervened and around fifteen hundred individuals were arrested.
The justices found that the rioters had been encouraged by him whose scheme, they said, was for the national armed forces to take action, restore order and reinstate his authority.
At the time, his attorneys called the over 27-year sentence extremely harsh.
He was also prohibited from seeking elected position until the year 2060 - eight years after the completion of his term.
The ex-leader called the legal proceedings a targeted investigation" and said it was intended to stop him participating in the 2026 presidential election.
