Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under domestic detention.
The former head of state was sentenced of planning a armed takeover in September and handed more than over two decades in incarceration, but he was staying under house arrest pending appeals.
High Court Judge 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 ankle monitor and a call for a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Escape Concerns
In a paperwork permitting the arrest, Justice Moraes said intelligence from the centre monitoring the former president's confinement suggested the one-time head of state's plan to remove the surveillance device to guarantee victory in his getaway".
This, it said, would be "facilitated by the confusion caused by the protest called by his child.
His son, Flávio Bolsonaro, who works as a legislator, called for a assembly of his followers near his father's house to take place on Saturday night.
His son wrote on online platforms on the previous day: "Are you going to fight for your homeland, or see it all from your phone there on your sofa? I urge you to battle with us."
He said the vigil would be so supporters could seek divine intervention for his health and for the return of democracy in our nation."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the potential of Bolsonaro's move to embassies near the home, considering that the inquiries revealed a background of arranging to ask for protection through a diplomatic representation", a declaration said.
The court filing emphasizes that the US embassy in the capital, the capital city, is positioned around 8 miles from Bolsonaro's home.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow right-wing populist American leader Trump, prompting him to enact a fifty percent tax on goods coming from Brazil.
The former president is being held in a federal law enforcement building in Brazil's capital city and will undergo a detention review on Sunday.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to allow him to fulfill his full incarceration period under home confinement, with tracking devices.
They also petitioned that Bolsonaro be authorized to leave his home for medical care, saying he required regular treatment for lung conditions and other illnesses.
Details of Guilty Verdict
Bolsonaro was found guilty of orchestrating a conspiracy aimed at maintaining his control after he lost the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which included plans to kill the current president and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the endorsement of the armed forces officials. Lula was sworn in without issue on 1 January 2023.
But a following week, on the eighth of January, thousands of Bolsonaro supporters attacked and damaged official structures in the federal district, Brazil's capital.
The security forces took action and around fifteen hundred individuals were taken into custody.
The justices found that the demonstrators had been provoked by the former president whose plan, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the moment, the legal team called the decades-long sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - eight years later after the end of his sentence.
The ex-leader called the legal proceedings a "witch hunt and said it was designed to prevent him participating in the 2026 presidential election.
