Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under domestic detention.
The ex-president was found guilty of planning a armed takeover in the ninth month and sentenced more than a 27-year term in incarceration, but he remained under home detention pending appeals.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a precautionary step after "new facts" came to light.
This encompassed trying to remove his ankle monitor and a summons to a demonstration that could "allow for a chance to flee".
Judicial Records Show Escape Concerns
In a filing authorising the custody, Justice Moraes said intelligence from the unit overseeing the former president's confinement suggested the ex-president's plan to remove the tracking monitor to secure accomplishment in his escape.
This, it said, would be "facilitated by the confusion caused by the protest called by his child.
His son, his son Flávio, who works as a legislator, called for a assembly of his supporters near his father's house to take place on Saturday night.
The senator wrote on digital networks on last Friday: "Are you going to fight for your nation, or watch it all from your smartphone there on your settee? I invite you to struggle with us."
He said the gathering would be so backers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of Bolsonaro's "relocation to diplomatic missions near the residence, considering that the inquiries revealed a history of organizing to seek refuge through a embassy office", a declaration said.
The legal document underscores that the American diplomatic mission in the capital, the capital city, is situated around 8 miles from Bolsonaro's home.
International Reactions
The former president's legal troubles have provoked anger from fellow conservative nationalist American leader President Trump, causing him to enact a fifty percent tax on imports of Brazilian goods.
He is being kept in a national police facility in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on last Friday that the ex-leader's attorneys asked the Top Court to authorize him to complete his entire prison term under home confinement, with electronic monitoring.
They also asked that he be authorized to exit his dwelling for medical care, saying he needed ongoing care for lung conditions and other ailments.
Background on Conviction
Bolsonaro was found guilty of heading a scheme aimed at retaining his authority after he failed to win the national vote to his ideological adversary, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a plot which involved plans to assassinate his opponent and his vice-presidential running mate, Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been presiding over his judicial proceedings.
The plot was stopped because it couldn't obtain the support of the armed forces officials. His successor was took office without issue on 1 January 2023.
But a seven days after, on 8 January, numerous his followers stormed and vandalised government buildings in the federal district, Brazil's capital.
The law enforcement took action and around approximately 1,500 persons were detained.
The justices found that the protesters had been incited by him whose plan, they said, was for the Brazilian military to take action, reestablish control and reinstate his authority.
At the time, the legal team called the decades-long sentence unreasonably severe".
He was also prohibited from campaigning for office until 2060 - a decade minus two years after the conclusion of his imprisonment.
The former president called the court case a political persecution and said it was designed to prevent him competing in the next presidential race.
