Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under home confinement.
The former head of state was convicted of orchestrating a armed takeover in the ninth month and given more than over two decades in prison, but he was staying under confinement pending appeals.
Top Judicial Official Alexandre de Moraes said the decision to arrest the septuagenarian politician was a safety action after recent developments came to light.
This involved seeking to disable his ankle monitor and a call for a supporters' gathering that could facilitate a possible escape.
Legal Document Reveals Escape Risks
In a filing authorising the custody, Justice Moraes said data from the facility tracking Bolsonaro's house arrest suggested the former leader's plan to remove the electronic ankle bracelet to ensure success in his flight.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his child.
His child, Flávio, who works as a congressional representative, called for a assembly of his backers near his father's house to take place on Saturday night.
The senator wrote on online platforms on last Friday: Do you plan to struggle for your nation, or observe everything from your phone there on your settee? I invite you to struggle with us."
He said the vigil would be so backers could seek divine intervention for his health and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the possibility of the former president's "relocation to embassies near the dwelling, considering that the probes revealed a history of organizing to seek refuge through a diplomatic representation", a announcement said.
The court filing underscores that the American diplomatic mission in the capital, the capital city, is located around 13km from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist United States President President Trump, leading him to implement a half-rate duty on Brazilian product imports.
Bolsonaro is being detained in a Federal Police station in Brazil's capital city and will experience a imprisonment assessment on the following day.
Latest Court Petitions
It was only on Friday that the his legal team asked the Top Court to authorize him to fulfill his full incarceration period under house arrest, with tracking devices.
They also requested that he be allowed to exit his dwelling for medical care, saying he needed regular treatment for respiratory ailments and other ailments.
Context of Sentencing
The former president was determined responsible of leading a conspiracy aimed at retaining his authority after he lost the 2022 election to his ideological adversary, President Lula.
Supreme Court justices said that he had knowledge of a plan which encompassed plans to assassinate his opponent and his vice-presidential running mate, Alckmin, and to arrest and execute the presiding judge - the High Court judge who has been overseeing his judicial proceedings.
The scheme was thwarted because it failed to get the backing of the armed forces officials. His successor was sworn in without incident on January 1st, 2023.
But a seven days after, on the eighth of January, many his followers stormed and vandalised government buildings in the national capital, Brazil's capital.
The security forces took action and around approximately 1,500 persons were arrested.
The magistrates found that the protesters had been encouraged by Bolsonaro whose strategy, they said, was for the national armed forces to take action, restore order and return him to office.
At the moment, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from seeking elected position until 2060 - a decade minus two years after the end of his sentence.
The one-time head of state called the trial a political persecution and said it was intended to stop him running in the next presidential race.
