Bolsonaro has been taken into custody after authorities concluded he posed a serious risk of fleeing while under home confinement.
The one-time leader was sentenced of planning a military coup in September and handed more than 27 years in jail, but he remained under house arrest pending court reviews.
High Court Judge Justice Moraes said the decision to arrest the elderly politician was a preventative measure after recent developments emerged.
This encompassed trying to remove his ankle monitor and a call for a demonstration that could facilitate a possible escape.
Legal Document Reveals Escape Concerns
In a document approving the detention, Justice Moraes said data from the centre monitoring the former president's confinement suggested the one-time head of state's "intention to break the tracking monitor to secure accomplishment in his flight.
This, it said, would be "facilitated by the confusion caused by the gathering called by his child.
His child, Flávio, who serves as a senator, called for a assembly of his backers near his father's house to take place on the weekend.
The senator wrote on social media on last Friday: "Are you going to fight for your homeland, or observe everything from your smartphone there on your couch? I invite you to fight with us."
He said the gathering would be so supporters could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the chance of his transfer to embassies near the dwelling, considering that the investigations revealed a record of arranging to ask for protection through a diplomatic representation", a announcement said.
The court filing emphasizes that the United States embassy in the federal district, Brasilia, is situated around 13km from the former president's residence.
Global Responses
The former president's legal troubles have drawn the ire of fellow populist conservative American leader President Trump, leading him to impose a half-rate duty on imports of Brazilian goods.
Bolsonaro is being kept in a Federal Police station in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the High Court to permit him to complete his entire prison term under home confinement, with electronic monitoring.
They also petitioned that Bolsonaro be permitted to leave his home for medical treatment, saying he needed frequent medical attention for respiratory ailments and other illnesses.
Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a plot aimed at retaining his authority after he lost the national vote to his left-wing rival, President Lula.
Supreme Court justices said that he had knowledge of a plan which encompassed plans to murder his opponent and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute the presiding judge - the Supreme Court justice who has been overseeing Bolsonaro's trial.
The plot was prevented because it failed to get the endorsement of the military leaders. His successor was inaugurated without problem on 1 January 2023.
But a following week, on the eighth of January, numerous his followers attacked and damaged government buildings in the federal district, Brasília.
The law enforcement intervened and around approximately 1,500 persons were taken into custody.
The justices found that the demonstrators had been encouraged by the former president whose scheme, they said, was for the Brazilian military to intervene, restore order and reinstate his authority.
At the period, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also barred from campaigning for office until twenty-sixty - eight years after the end of his sentence.
The one-time head of state called the court case a "witch hunt and said it was designed to prevent him running in the next presidential race.
