Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of orchestrating a armed takeover in the ninth month and given more than a 27-year term in incarceration, but he remained under confinement pending court reviews.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a precautionary step after "new facts" emerged.
This involved seeking to disable his tracking device and a summons to a supporters' gathering that could facilitate a chance to flee".
In a filing authorising the detention, the magistrate said intelligence from the facility tracking his home detention suggested the former leader's aim to disable the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the disorder caused by the gathering called by his offspring.
His child, Flávio, who holds office as a congressional representative, called for a meeting of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on online platforms on Friday: Will you battle for your homeland, or watch it all from your smartphone there on your sofa? I invite you to struggle with us."
He said the gathering would be so backers could offer prayers for his health and for the reestablishment of democratic governance in our land."
Part of Justice Moraes's ruling was the potential of the former president's transfer to diplomatic missions near the dwelling, considering that the probes revealed a history of arranging to seek refuge through a consular facility", a declaration said.
The judicial paperwork emphasizes that the United States embassy in the capital, Brasilia, is located around 8 miles from the former president's residence.
The former president's legal troubles have drawn the ire of fellow conservative nationalist US President Donald Trump, prompting him to enact a half-rate duty on imports of Brazilian goods.
He is being detained in a national police facility in the capital and will have a custody hearing on the following day.
It was only on last Friday that the his legal team asked the Top Court to authorize him to serve his whole jail sentence under house arrest, with tracking devices.
They also petitioned that he be authorized to exit his dwelling for healthcare, saying he needed frequent medical attention for respiratory ailments and other illnesses.
The former president was determined responsible of orchestrating a scheme aimed at retaining his authority after he failed to win the 2022 election to his political opponent, President Lula.
High Court judges said that he had knowledge of a plot which encompassed plans to assassinate the current president and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder Justice Moraes - the top judicial official who has been managing his judicial proceedings.
The scheme was stopped because it didn't receive the backing of the armed forces officials. Lula was took office without issue on January 1st, 2023.
But a seven days after, on January 8th, thousands of his followers invaded and destroyed government buildings in the federal district, Brazil's capital.
The police intervened and around approximately 1,500 persons were arrested.
The magistrates found that the rioters had been provoked by the former president whose plan, they said, was for the national armed forces to take action, restore order and bring him back to power.
At the time, the legal team called the over 27-year sentence extremely harsh.
He was also banned from running for public office until 2060 - eight years after the end of his sentence.
The ex-leader called the court case a political persecution and said it was aimed at blocking him competing in the 2026 national vote.
