The former Brazilian leader has been detained after authorities determined he posed a serious risk of fleeing while under home confinement.
The ex-president was convicted of planning a military coup in the ninth month and handed more than a 27-year term in jail, but he remained under home detention pending court reviews.
Top Judicial Official the presiding justice said the move to detain the septuagenarian politician was a preventative measure after "new facts" came to light.
This included trying to remove his ankle monitor and a invitation to a supporters' gathering that could enable a possible escape.
Judicial Records Show Escape Concerns
In a document approving the detention, the judge said data from the facility tracking Bolsonaro's house arrest suggested the one-time head of state's plan to remove the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his son.
His son, Flávio, who holds office as a legislator, called for a assembly of his backers near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your nation, or watch it all from your phone there on your couch? I invite you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his physical condition and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the potential of the former president's transfer to foreign missions near the dwelling, considering that the probes revealed a record of arranging to seek refuge through a diplomatic representation", a statement said.
The legal document underscores that the United States embassy in the federal district, Brasilia, is positioned around 13km from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have provoked anger from fellow right-wing populist American leader President Trump, leading him to implement a 50% tariff on goods coming from Brazil.
He is being detained in a national police facility in Brazil's capital city and will have a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on Friday that the his legal team asked the High Court to allow him to serve his whole jail sentence under home confinement, with digital surveillance.
They also asked that Bolsonaro be permitted to exit his dwelling for healthcare, saying he needed frequent medical attention for respiratory ailments and other illnesses.
Context of Sentencing
Bolsonaro was convicted of heading a scheme aimed at keeping him in power after he lost the national vote to his left-wing rival, President Lula.
Top judicial officials said that he had knowledge of a scheme which encompassed plans to assassinate the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Justice Moraes - the top judicial official who has been managing Bolsonaro's trial.
The plot was thwarted because it didn't receive the endorsement of the armed forces officials. Lula was took office without issue on 1 January 2023.
But a seven days after, on 8 January, thousands of Bolsonaro supporters stormed and vandalised official structures in the capital, Brazil's capital.
The law enforcement took action and around 1,500 people were detained.
The justices found that the demonstrators had been provoked by Bolsonaro whose scheme, they said, was for the national armed forces to step in, reestablish control and bring him back to power.
At the period, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also banned from campaigning for office until 2060 - eight years later after the completion of his term.
The one-time head of state called the court case a political persecution and said it was aimed at blocking him participating in the 2026 presidential election.
