Bolsonaro has been arrested after authorities concluded he posed a concrete flight risk while under home confinement.
The ex-president was convicted of planning a armed takeover in last fall and sentenced more than over two decades in prison, but he was staying under house arrest pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the septuagenarian politician was a safety action after recent developments emerged.
This involved seeking to disable his electronic bracelet and a call for a supporters' gathering that could facilitate a potential flight.
Legal Document Reveals Flight Fears
In a document approving the custody, the magistrate said information from the centre monitoring his home detention suggested the one-time head of state's plan to remove the tracking monitor to ensure success in his escape.
This, it said, would be "facilitated by the confusion caused by the gathering called by his son.
His son, Flávio Bolsonaro, who holds office as a congressional representative, called for a assembly of his backers near his father's house to take place on Saturday evening.
The senator wrote on digital networks on the previous day: Will you battle for your homeland, or see it all from your smartphone there on your sofa? I urge you to fight with us."
He said the gathering would be so supporters could seek divine intervention for his health and for the reestablishment of democratic governance in our country."
Diplomatic Refuge Fears
Part of the magistrate's determination was the potential of his move to diplomatic missions near the home, considering that the inquiries revealed a history of organizing to ask for protection through a diplomatic representation", a statement said.
The judicial paperwork underscores that the US embassy in the capital, the capital city, is situated around 8 miles from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow right-wing populist United States President President Trump, causing him to enact a half-rate duty on imports of Brazilian goods.
He is being detained in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to allow him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that he be authorized to depart his residence for healthcare, saying he demanded frequent medical attention for pulmonary infections and other health problems.
Details of Guilty Verdict
Bolsonaro was convicted of orchestrating a scheme aimed at maintaining his control after he lost the 2022 election to his political opponent, President Lula.
Supreme Court justices said that he knew of a plot which encompassed plans to murder his opponent and his running partner, his vice-presidential candidate, and to arrest and execute the presiding judge - the High Court judge who has been overseeing his judicial proceedings.
The plot was stopped because it couldn't obtain the endorsement of the military leaders. The current president was inaugurated without problem on the first day of 2023.
But a following week, on the eighth of January, many his followers invaded and destroyed official structures in the federal district, Brasília.
The law enforcement took action and around approximately 1,500 persons were arrested.
The judges found that the protesters had been provoked by Bolsonaro whose plan, they said, was for the country's army to step in, reestablish control and bring him back to power.
At the time, the legal team called the decades-long sentence unreasonably severe".
He was also barred from running for public office until twenty-sixty - eight years after the end of his sentence.
The former president called the legal proceedings a targeted investigation" and said it was aimed at blocking him running in the 2026 national vote.
