Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under home confinement.
The former head of state was sentenced of plotting a armed takeover in September and given more than over two decades in jail, but he was staying under home detention pending appeals.
Top Judicial Official Alexandre de Moraes said the action to imprison the septuagenarian politician was a preventative measure after recent developments were revealed.
This involved seeking to disable his electronic bracelet and a invitation to a demonstration that could "allow for a potential flight.
Judicial Records Show Escape Concerns
In a document approving the arrest, the judge said data from the facility tracking his home detention suggested the ex-president's plan to remove the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be assisted by the chaos caused by the gathering called by his offspring.
His offspring, Flávio, who serves as a senator, called for a meeting of his backers near his father's house to take place on the weekend.
Flávio Bolsonaro wrote on digital networks on the previous day: Will you battle for your nation, or observe everything from your smartphone there on your settee? I invite you to struggle with us."
He said the demonstration would be so supporters could offer prayers for his physical condition and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the chance of his "relocation to diplomatic missions near the home, considering that the inquiries revealed a history of arranging to request asylum through a embassy office", a statement said.
The court filing underscores that the American diplomatic mission in the capital, Brasilia, is located around 13km from Bolsonaro's home.
Global Responses
His judicial problems have provoked anger from fellow populist conservative American leader Donald Trump, causing him to impose a fifty percent tax on Brazilian product imports.
Bolsonaro is being held in a federal law enforcement building in the capital 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 allow him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that Bolsonaro be permitted to depart his residence for medical care, saying he required ongoing care for respiratory ailments and other health problems.
Details of Guilty Verdict
The former president was convicted of leading a scheme aimed at maintaining his control after he lost the 2022 election to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a scheme which encompassed plans to assassinate his opponent and his VP candidate, his vice-presidential candidate, and to arrest and execute Justice Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The plot was prevented because it couldn't obtain the endorsement of the army and air force commanders. Lula was sworn in without problem on January 1st, 2023.
But a week later, on 8 January, numerous his followers attacked and damaged official structures in the federal district, the capital city.
The police stepped in and around 1,500 people were arrested.
The justices found that the demonstrators had been provoked by the former president whose scheme, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the time, his attorneys called the over 27-year sentence "absurdly excessive.
He was also prohibited from running for public office until the year 2060 - eight years later after the end of his sentence.
The one-time head of state called the court case a targeted investigation" and said it was aimed at blocking him participating in the next presidential race.
