Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under domestic detention.
The former head of state was convicted of orchestrating a armed takeover in the ninth month and handed more than over two decades in jail, but he remained under house arrest pending court reviews.
Top Judicial Official Alexandre de Moraes said the action to imprison the 70-year-old politician was a preventative measure after fresh information came to light.
This included trying to remove his ankle monitor and a call for a supporters' gathering that could facilitate a potential flight.
Legal Document Reveals Escape Concerns
In a document approving the detention, Justice Moraes said data from the centre monitoring his home detention suggested the ex-president's plan to remove the surveillance device to secure accomplishment in his escape.
This, it said, would be made easier by the disorder caused by the protest called by his son.
His son, his son Flávio, who serves as a senator, called for a meeting of his followers near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on Friday: Do you plan to struggle for your country, or watch it all from your mobile device there on your sofa? I call on you to struggle with us."
He said the demonstration would be so followers could offer prayers for his health and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of the former president's move to diplomatic missions near the residence, considering that the probes revealed a history of organizing to request asylum through a diplomatic representation", a announcement said.
The court filing emphasizes that the United States embassy in the federal district, Brasilia, is positioned around 8 miles from the former president's residence.
Global Responses
His judicial problems have generated frustration from fellow conservative nationalist United States President Donald Trump, prompting him to enact a 50% tariff on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the Supreme Court to permit him to serve his whole jail sentence under home confinement, with electronic monitoring.
They also asked that the former president be authorized to exit his dwelling for medical treatment, saying he demanded frequent medical attention for pulmonary infections and other illnesses.
Context of Sentencing
He was convicted of leading a plot aimed at retaining his authority after he was defeated in the 2022 election to his ideological adversary, Lula.
Supreme Court justices said that he knew of a plot which encompassed plans to assassinate the current president and his running partner, his vice-presidential candidate, and to detain and kill Justice Moraes - the Supreme Court justice who has been managing the former president's case.
The scheme was thwarted because it failed to get the backing of the army and air force commanders. The current president was sworn in without issue on the first day of 2023.
But a following week, on the eighth of January, numerous his backers invaded and destroyed government buildings in the federal district, Brasília.
The security forces intervened and around fifteen hundred individuals were detained.
The judges found that the protesters had been encouraged by Bolsonaro whose scheme, they said, was for the country's army to step in, bring back stability and bring him back to power.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also prohibited from campaigning for office until the year 2060 - 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 next presidential race.
