Bolsonaro has been detained after authorities found he posed a concrete flight risk while under home confinement.
The ex-president was convicted of planning a government overthrow in the ninth month and handed more than a 27-year term in jail, but he continued under home detention pending court reviews.
High Court Judge the presiding justice said the move to detain the 70-year-old politician was a preventative measure after recent developments were revealed.
This included attempting to break his ankle monitor and a summons to a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Escape Concerns
In a filing authorising the arrest, Justice Moraes said data from the centre monitoring his home detention suggested the ex-president's "intention to break the tracking monitor to guarantee victory in his getaway".
This, it said, would be assisted by the disorder caused by the gathering called by his child.
His offspring, Flávio, who works as a senator, called for a meeting of his followers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on online platforms on Friday: Do you plan to struggle for your nation, or watch it all from your phone there on your couch? I urge you to battle with us."
He said the vigil would be so supporters could "pray for his well-being and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the possibility of Bolsonaro's transfer to foreign missions near the dwelling, considering that the investigations revealed a background of arranging to ask for protection through a diplomatic representation", a declaration said.
The legal document underscores that the United States embassy in the capital, Brazil's capital, is located around 8 miles from the former president's residence.
International Reactions
The former president's legal troubles have provoked anger from fellow populist conservative American leader Trump, causing him to implement a half-rate duty on imports of Brazilian goods.
The former president is being kept in a national police facility in the capital and will experience a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to permit him to serve his whole jail sentence under domestic detention, with tracking devices.
They also petitioned that Bolsonaro be permitted to depart his residence for medical treatment, saying he needed regular treatment for respiratory ailments and other health problems.
Details of Guilty Verdict
The former president was found guilty of orchestrating a scheme aimed at retaining his authority after he failed to win the 2022 election to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a scheme which involved plans to murder Lula and his VP candidate, his vice-presidential candidate, and to arrest and execute Justice Moraes - the Supreme Court justice who has been overseeing the former president's case.
The conspiracy was stopped because it didn't receive the backing of the army and air force commanders. His successor was inaugurated without problem on January 1st, 2023.
But a week later, on 8 January, many his followers invaded and destroyed public facilities in the national capital, Brasília.
The security forces stepped in and around approximately 1,500 persons were taken into custody.
The justices found that the rioters had been encouraged by him whose strategy, they said, was for the national armed forces to intervene, restore order and reinstate his authority.
At the moment, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also barred from seeking elected position until twenty-sixty - eight years after the completion of his term.
The ex-leader called the legal proceedings a targeted investigation" and said it was intended to stop him running in the 2026 presidential election.
