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 found guilty of planning a armed takeover in September and sentenced more than over two decades in jail, but he was staying under house arrest pending appeals.
Top Judicial Official Justice Moraes said the move to detain the septuagenarian politician was a safety action after recent developments were revealed.
This encompassed trying to remove his electronic bracelet and a summons to a demonstration that could enable a possible escape.
Legal Document Reveals Escape Concerns
In a document approving the arrest, Justice Moraes said data from the facility tracking his home detention suggested the former leader's "intention to break the surveillance device to secure accomplishment in his getaway".
This, it said, would be assisted by the confusion caused by the protest called by his child.
His offspring, Flávio, who holds office as a congressional representative, called for a assembly of his backers near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on last Friday: Will you battle for your homeland, or observe everything from your smartphone there on your settee? I invite you to fight with us."
He said the gathering would be so backers could "pray for his physical condition and for the return of democracy in our land."
Foreign Shelter Risks
Part of the judge's decision was the chance of his move to diplomatic missions near the home, considering that the inquiries revealed a background of organizing to ask for protection through a diplomatic representation", a statement said.
The court filing emphasizes that the United States embassy in the national capital, the capital city, is situated around 13km from the former president's residence.
Global Responses
His judicial problems have drawn the ire of fellow conservative nationalist US President Donald Trump, causing him to implement a fifty percent tax on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brasilia and will have a detention review on Sunday.
Recent Judicial Appeals
It was only on the previous day that the former president's lawyers asked the High Court to allow him to complete his entire prison term under home confinement, with electronic monitoring.
They also requested that Bolsonaro be allowed to exit his dwelling for healthcare, saying he needed frequent medical attention for respiratory ailments and other health problems.
Context of Sentencing
He was found guilty of heading a scheme aimed at retaining his authority after he lost the 2022 election to his political opponent, President Lula.
Supreme Court justices said that he knew of a plan which encompassed plans to assassinate the current president and his VP candidate, Geraldo Alckmin, and to detain and kill Justice Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was stopped because it failed to get the backing of the military leaders. Lula was inaugurated without problem on 1 January 2023.
But a following week, on 8 January, numerous his backers attacked and damaged public facilities in the national capital, Brasília.
The security forces intervened and around fifteen hundred individuals were taken into custody.
The justices found that the rioters had been encouraged by him whose scheme, they said, was for the Brazilian military to take action, restore order and reinstate his authority.
At the time, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also prohibited from campaigning for office until twenty-sixty - eight years after the end of his sentence.
The former president called the court case a "witch hunt and said it was intended to stop him running in the 2026 national vote.
