The former Brazilian leader has been taken into custody after authorities concluded he posed a concrete flight risk while under domestic detention.
The ex-president was convicted of orchestrating a armed takeover in last fall and given more than 27 years in jail, but he continued under confinement pending legal challenges.
High Court Judge Alexandre de Moraes said the action to imprison the septuagenarian politician was a preventative measure after "new facts" came to light.
This encompassed attempting to break his ankle monitor and a summons to a demonstration that could "allow for a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the judge said information from the facility tracking the former president's confinement suggested the former leader's plan to remove the electronic ankle bracelet to guarantee victory in his flight.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his child.
His child, his son Flávio, who holds office as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on Friday: Will you battle for your homeland, or watch it all from your phone there on your settee? I invite you to battle with us."
He said the gathering would be so followers could "pray for his well-being and for the return of democracy in our nation."
Foreign Shelter Risks
Part of the magistrate's decision was the possibility of the former president's transfer to foreign missions near the residence, considering that the inquiries revealed a background of arranging to ask for protection through a embassy office", a announcement said.
The judicial paperwork highlights that the US embassy in the national capital, Brazil's capital, is situated around approximately 13 kilometers from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist United States President Donald Trump, prompting him to impose a half-rate duty on Brazilian product imports.
He is being detained in a federal law enforcement building in Brazil's capital city and will have a detention review on the following day.
Recent Judicial Appeals
It was only on the previous day that the ex-leader's attorneys asked the High Court to authorize him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also asked that the former president be permitted to exit his dwelling for healthcare, saying he demanded ongoing care for lung conditions and other illnesses.
Details of Guilty Verdict
Bolsonaro was convicted of heading a plot aimed at retaining his authority after he failed to win the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he had knowledge of a scheme which included plans to kill Lula and his running partner, Alckmin, and to imprison and murder Alexandre de Moraes - the top judicial official who has been presiding over his judicial proceedings.
The scheme was prevented because it failed to get the endorsement of the armed forces officials. Lula was inaugurated without problem on 1 January 2023.
But a week later, on the eighth of January, thousands of his backers attacked and damaged official structures in the federal district, the capital city.
The security forces stepped in and around fifteen hundred individuals were arrested.
The magistrates found that the demonstrators had been incited by him whose plan, they said, was for the national armed forces to take action, bring back stability and reinstate his authority.
At the period, his attorneys called the over 27-year sentence unreasonably severe".
He was also banned from running for public office until the year 2060 - eight years later after the conclusion of his imprisonment.
The former president called the court case a "witch hunt and said it was intended to stop him running in the next presidential race.
