Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of planning a military coup in September and given more than 27 years in incarceration, but he was staying under house arrest pending legal challenges.
High Court Judge Justice Moraes said the action to imprison the 70-year-old politician was a precautionary step after fresh information emerged.
This encompassed trying to remove his ankle monitor and a call for a supporters' gathering that could "allow for a possible escape.
Legal Document Reveals Escape Risks
In a filing authorising the custody, Justice Moraes said information from the centre monitoring his home detention suggested the ex-president's "intention to break the tracking monitor to ensure success in his flight.
This, it said, would be "facilitated by the disorder caused by the gathering called by his son.
His offspring, Flávio Bolsonaro, who holds office as a legislator, called for a assembly of his backers near his father's house to take place on the weekend.
His son wrote on online platforms on Friday: Will you battle for your homeland, or see it all from your mobile device there on your settee? I invite you to struggle with us."
He said the demonstration would be so supporters could seek divine intervention for his health and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of the judge's decision was the chance of his transfer to diplomatic missions near the home, considering that the inquiries revealed a history of organizing to ask for protection through a diplomatic representation", a announcement said.
The court filing highlights that the US embassy in the federal district, the capital city, is positioned around 8 miles from the former president's residence.
International Reactions
His judicial problems have provoked anger from fellow populist conservative American leader President Trump, causing him to impose a half-rate duty on imports of Brazilian goods.
The former president is being held in a federal law enforcement building in Brasilia and will have a imprisonment assessment on the following day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the Top Court to allow him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also asked that Bolsonaro be authorized to depart his residence for medical care, saying he needed regular treatment for respiratory ailments and other ailments.
Details of Guilty Verdict
He was determined responsible of heading a scheme aimed at retaining his authority after he was defeated in the 2022 election to his political opponent, President Lula.
Supreme Court justices said that he had knowledge of a plot which involved plans to kill his opponent and his running partner, his vice-presidential candidate, and to detain and kill Justice Moraes - the top judicial official who has been managing Bolsonaro's trial.
The plot was prevented because it couldn't obtain the endorsement of the military leaders. Lula was sworn in without incident on the first day of 2023.
But a seven days after, on January 8th, thousands of his backers stormed and vandalised official structures in the capital, Brasília.
The police took action and around approximately 1,500 persons were arrested.
The judges found that the rioters had been provoked by Bolsonaro whose plan, they said, was for the Brazilian military to step in, restore order and reinstate his authority.
At the moment, Bolsonaro's lawyers called the over 27-year sentence extremely harsh.
He was also prohibited from seeking elected position until twenty-sixty - eight years later after the conclusion of his imprisonment.
The former president called the trial a targeted investigation" and said it was designed to prevent him running in the 2026 national vote.
