Bolsonaro has been taken into custody after authorities concluded he posed a concrete flight risk while under house arrest.
The one-time leader was found guilty of plotting a armed takeover in September and given more than a 27-year term in incarceration, but he remained under confinement pending legal challenges.
Top Judicial Official Justice Moraes said the action to imprison the septuagenarian politician was a safety action after "new facts" emerged.
This included seeking to disable his ankle monitor and a invitation to a supporters' gathering that could "allow for a possible escape.
Court Filing Details Escape Concerns
In a document approving the arrest, Justice Moraes said data from the centre monitoring the former president's confinement suggested the ex-president's plan to remove the electronic ankle bracelet to ensure success in his escape.
This, it said, would be assisted by the chaos caused by the protest called by his child.
His child, Flávio Bolsonaro, who works as a legislator, called for a meeting of his backers near the former president's residence to take place on the weekend.
The senator wrote on online platforms on the previous day: Do you plan to struggle for your homeland, or see it all from your phone there on your sofa? I urge you to battle with us."
He said the demonstration would be so supporters could offer prayers for his well-being and for the return of democracy in our country."
Foreign Shelter Risks
Part of the magistrate's ruling was the chance of the former president's move to embassies near the home, considering that the inquiries revealed a history of organizing to ask for protection through a diplomatic representation", a announcement said.
The legal document emphasizes that the US embassy in the federal district, Brazil's capital, is positioned around 8 miles from the former president's residence.
Global Responses
His judicial problems have drawn the ire of fellow conservative nationalist US President Donald Trump, prompting him to implement a 50% tariff on goods coming from Brazil.
The former president is being detained in a Federal Police station in Brazil's capital city and will undergo a imprisonment assessment on the following day.
Latest Court Petitions
It was only on the previous day that the his legal team asked the High Court to authorize him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also asked that the former president be authorized to depart his residence for healthcare, saying he required frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
The former president was found guilty of orchestrating a scheme aimed at maintaining his control after he failed to win the 2022 election to his political opponent, Lula.
High Court judges said that he knew of a scheme which encompassed plans to kill the current president and his VP candidate, Alckmin, and to detain and kill Justice Moraes - the top judicial official who has been presiding over his judicial proceedings.
The scheme was prevented because it didn't receive the endorsement of the army and air force commanders. His successor was inaugurated without incident on January 1st, 2023.
But a following week, on January 8th, thousands of Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brasília.
The law enforcement stepped in and around approximately 1,500 persons were detained.
The magistrates found that the demonstrators had been provoked by Bolsonaro whose plan, they said, was for the Brazilian military to take action, reestablish control and return him to office.
At the moment, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also prohibited from running for public office until 2060 - a decade minus two years after the completion of his term.
The former president called the trial a political persecution and said it was aimed at blocking him participating in the 2026 national vote.
