Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under domestic detention.
The one-time leader was sentenced of plotting a military coup in September and given more than over two decades in incarceration, but he was staying under house arrest pending appeals.
Top Judicial Official Justice Moraes said the action to imprison the elderly politician was a safety action after "new facts" emerged.
This included seeking to disable his electronic bracelet and a summons to a supporters' gathering that could "allow for a chance to flee".
Court Filing Details Flight Fears
In a filing authorising the custody, Justice Moraes said information from the unit overseeing Bolsonaro's house arrest suggested the one-time head of state's aim to disable the tracking monitor to secure accomplishment in his getaway".
This, it said, would be assisted by the confusion caused by the demonstration called by his offspring.
His child, Flávio, who works as a congressional representative, called for a meeting of his backers near his father's house to take place on Saturday evening.
His son wrote on online platforms on the previous day: Will you battle for your country, or see it all from your smartphone there on your settee? I urge you to struggle with us."
He said the gathering would be so backers could "pray for his health and for the return of democracy in our nation."
Embassy Asylum Concerns
Part of the judge's ruling was the possibility of Bolsonaro's move to embassies near the home, considering that the probes revealed a history of arranging to ask for protection through a consular facility", a statement said.
The court filing underscores that the United States embassy in the capital, the capital city, is positioned around 8 miles from Bolsonaro's home.
Worldwide Consequences
His judicial problems have generated frustration from fellow conservative nationalist American leader President Trump, prompting him to implement a 50% tariff on imports of Brazilian goods.
The former president is being detained in a national police facility in Brasilia and will undergo a imprisonment assessment on the following day.
Latest Court Petitions
It was only on Friday that the his legal team asked the Supreme Court to permit him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also requested that he be allowed to exit his dwelling for medical treatment, saying he demanded ongoing care for pulmonary infections and other ailments.
Context of Sentencing
The former president was determined responsible of orchestrating a plot aimed at maintaining his control after he lost the national vote to his political opponent, Lula.
Supreme Court justices said that he knew of a scheme which encompassed plans to kill the current president and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been managing his judicial proceedings.
The conspiracy was prevented because it couldn't obtain the support of the army and air force commanders. His successor was took office without problem on January 1st, 2023.
But a seven days after, on January 8th, many Bolsonaro supporters stormed and vandalised government buildings in the federal district, the capital city.
The police took action and around 1,500 people were taken into custody.
The magistrates found that the demonstrators had been provoked by Bolsonaro whose scheme, they said, was for the country's army to take action, restore order and bring him back to power.
At the time, Bolsonaro's lawyers called the over 27-year sentence unreasonably severe".
He was also prohibited from campaigning for office until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the trial a "witch hunt and said it was aimed at blocking him competing in the 2026 national vote.
