The former Brazilian leader has been detained after authorities found he posed a serious risk of fleeing while under domestic detention.
The ex-president was found guilty of orchestrating a armed takeover in September and given more than 27 years in prison, but he continued under confinement pending court reviews.
Top Judicial Official Justice Moraes said the move to detain the septuagenarian politician was a preventative measure after recent developments were revealed.
This included trying to remove his ankle monitor and a call for a supporters' gathering that could facilitate a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the magistrate said information from the centre monitoring the former president's confinement suggested the former leader's plan to remove the surveillance device to guarantee victory in his getaway".
This, it said, would be "facilitated by the disorder caused by the gathering called by his child.
His son, Flávio, who serves as a legislator, called for a gathering of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: "Are you going to fight for your nation, or see it all from your smartphone there on your settee? I urge you to struggle with us."
He said the demonstration would be so followers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of the magistrate's decision was the possibility of his move to diplomatic missions near the home, considering that the probes revealed a background of planning to ask for protection through a diplomatic representation", a statement said.
The legal document highlights that the United States embassy in the national capital, Brazil's capital, is situated around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have provoked anger from fellow conservative nationalist US President Donald Trump, leading him to implement a 50% tariff on goods coming from Brazil.
Bolsonaro is being held in a national police facility in Brazil's capital city and will experience a custody hearing on Sunday.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the Top Court to authorize him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also requested that the former president be allowed to exit his dwelling for medical treatment, saying he needed ongoing care for respiratory ailments and other health problems.
Details of Guilty Verdict
He was found guilty of orchestrating a plot aimed at retaining his authority after he failed to win the 2022 election to his left-wing rival, Lula.
Top judicial officials said that he knew of a plot which encompassed plans to murder his opponent and his vice-presidential running mate, Alckmin, and to imprison and murder Justice Moraes - the Supreme Court justice who has been presiding over the former president's case.
The scheme was stopped because it didn't receive the endorsement of the army and air force commanders. His successor was took office without issue on the first day of 2023.
But a week later, on 8 January, numerous his backers invaded and destroyed public facilities in the capital, the capital city.
The law enforcement stepped in and around approximately 1,500 persons were arrested.
The judges found that the protesters had been provoked by him whose scheme, they said, was for the Brazilian military to take action, reestablish control and reinstate his authority.
At the time, his attorneys called the decades-long sentence unreasonably severe".
He was also barred from seeking elected position until the year 2060 - eight years later after the conclusion of his imprisonment.
The former president called the legal proceedings a targeted investigation" and said it was intended to stop him participating in the 2026 national vote.
