Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The one-time leader was found guilty of plotting a government overthrow in the ninth month and sentenced more than 27 years in jail, but he was staying under confinement pending appeals.
High Court Judge the presiding justice said the decision to arrest the 70-year-old politician was a preventative measure after recent developments came to light.
This included attempting to break his electronic bracelet and a summons to a public vigil that could "allow for a potential flight.
Court Filing Details Escape Concerns
In a document approving the custody, Justice Moraes said information from the facility tracking the former president's confinement suggested the ex-president's plan to remove the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the disorder caused by the protest called by his child.
His child, his son Flávio, who holds office as a senator, called for a meeting of his supporters near the former president's residence to take place on Saturday night.
The senator wrote on digital networks on last Friday: "Are you going to fight for your nation, or see it all from your smartphone there on your couch? I invite you to fight with us."
He said the vigil would be so followers could seek divine intervention for his physical condition and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the potential of the former president's transfer to embassies near the residence, considering that the inquiries revealed a history of organizing to request asylum through a embassy office", a declaration said.
The judicial paperwork highlights that the American diplomatic mission in the federal district, Brasilia, is situated around approximately 13 kilometers from Bolsonaro's home.
International Reactions
The former president's legal troubles have provoked anger from fellow conservative nationalist United States President Trump, causing him to enact a half-rate duty on goods coming from Brazil.
He is being held in a Federal Police station in Brazil's capital city and will undergo a detention review on the following day.
Latest Court Petitions
It was only on Friday that the his legal team asked the Top Court to permit him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that the former president be authorized to depart his residence for medical care, saying he needed ongoing care for lung conditions and other health problems.
Context of Sentencing
The former president was determined responsible of leading a scheme aimed at maintaining his control after he lost the 2022 election to his political opponent, President Lula.
Supreme Court justices said that he was aware of a scheme which included plans to kill Lula and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder the presiding judge - the High Court judge who has been overseeing his judicial proceedings.
The plot was thwarted because it failed to get the backing of the armed forces officials. His successor was took office without problem on 1 January 2023.
But a seven days after, on 8 January, numerous his followers attacked and damaged public facilities in the national capital, Brazil's capital.
The law enforcement took action and around approximately 1,500 persons were arrested.
The judges found that the rioters had been incited by Bolsonaro whose strategy, they said, was for the Brazilian military to take action, reestablish control and return him to office.
At the period, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also prohibited from seeking elected position until 2060 - eight years later after the completion of his term.
The former president called the court case a targeted investigation" and said it was designed to prevent him competing in the 2026 presidential election.
