Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was convicted of plotting a government overthrow in September and handed more than over two decades in incarceration, but he remained under house arrest pending appeals.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the 70-year-old politician was a safety action after recent developments came to light.
This involved attempting to break his tracking device and a call for a supporters' gathering that could "allow for a chance to flee".
Legal Document Reveals Escape Risks
In a filing authorising the detention, Justice Moraes said information from the unit overseeing his home detention suggested the former leader's aim to disable the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be "facilitated by the confusion caused by the protest called by his son.
His offspring, his son Flávio, who serves as a congressional representative, called for a assembly of his supporters near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on social media on the previous day: Will you battle for your nation, or observe everything from your phone there on your couch? I invite you to battle with us."
He said the vigil would be so supporters could offer prayers for his well-being and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the chance of his transfer to diplomatic missions near the home, considering that the inquiries revealed a background of planning to ask for protection through a embassy office", a declaration said.
The court filing highlights that the United States embassy in the federal district, Brazil's capital, is situated around 13km from his dwelling.
Global Responses
The former president's legal troubles have generated frustration from fellow right-wing populist United States President Donald Trump, leading him to implement a fifty percent tax on Brazilian product imports.
Bolsonaro is being detained in a Federal Police station in the capital and will experience a detention review on Sunday.
Latest Court Petitions
It was only on last Friday that the former president's lawyers asked the High Court to allow him to complete his entire prison term under home confinement, with tracking devices.
They also asked that the former president be allowed to leave his home for medical care, saying he demanded ongoing care for respiratory ailments and other ailments.
Details of Guilty Verdict
The former president was convicted of heading a plot aimed at keeping him in power after he was defeated in the presidential race to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plan which encompassed plans to assassinate Lula and his VP candidate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been presiding over his judicial proceedings.
The plot was prevented because it failed to get the support of the armed forces officials. Lula was sworn in without issue on the first day of 2023.
But a seven days after, on the eighth of January, many Bolsonaro supporters attacked and damaged public facilities in the capital, Brazil's capital.
The police stepped in and around approximately 1,500 persons were taken into custody.
The judges found that the protesters had been encouraged by him whose strategy, they said, was for the Brazilian military to take action, restore order and reinstate his authority.
At the period, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also banned from campaigning for office until the year 2060 - eight years later after the completion of his term.
The one-time head of state called the court case a "witch hunt and said it was designed to prevent him participating in the next presidential race.
