Bolsonaro has been arrested after authorities concluded he posed a definite escape threat while under domestic detention.
The ex-president was convicted of orchestrating a military coup in last fall and sentenced more than 27 years in jail, but he remained under home detention pending court reviews.
Top Judicial Official the presiding justice said the move to detain the 70-year-old politician was a precautionary step after fresh information came to light.
This encompassed attempting to break his ankle monitor and a call for a demonstration that could "allow for a possible escape.
Judicial Records Show Flight Fears
In a filing authorising the arrest, Justice Moraes said intelligence from the unit overseeing his home detention suggested the former leader's plan to remove the surveillance device to secure accomplishment in his escape.
This, it said, would be assisted by the disorder caused by the gathering called by his offspring.
His son, Flávio, who serves as a senator, called for a meeting of his supporters near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on digital networks on the previous day: Do you plan to struggle for your homeland, or see it all from your mobile device there on your couch? I call on you to struggle with us."
He said the vigil would be so backers could offer prayers for his health and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of Justice Moraes's decision was the potential of Bolsonaro's transfer to diplomatic missions near the home, considering that the inquiries revealed a record of planning to seek refuge through a embassy office", a statement said.
The court filing highlights that the US embassy in the national capital, the capital city, is positioned around 13km from the former president's residence.
Global Responses
The former president's legal troubles have drawn the ire of fellow populist conservative US President President Trump, prompting him to implement a half-rate duty on imports of Brazilian goods.
He is being kept in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on the previous day that the former president's lawyers asked the Supreme Court to allow him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also petitioned that Bolsonaro be allowed to depart his residence for healthcare, saying he required frequent medical attention for lung conditions and other ailments.
Context of Sentencing
Bolsonaro was determined responsible of leading a conspiracy aimed at maintaining his control after he was defeated in the 2022 election to his ideological adversary, President Lula.
High Court judges said that he was aware of a scheme which encompassed plans to kill Lula and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Alexandre de Moraes - 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. The current president was inaugurated without issue on the first day of 2023.
But a following week, on the eighth of January, numerous his backers stormed and vandalised official structures in the national capital, the capital city.
The police stepped in and around 1,500 people were taken into custody.
The judges found that the rioters had been incited by him whose scheme, they said, was for the Brazilian military to step in, restore order and bring him back to power.
At the time, his attorneys called the over 27-year sentence extremely harsh.
He was also barred from campaigning for office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The former president called the legal proceedings a political persecution and said it was intended to stop him participating in the next presidential race.
