Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under home confinement.
The one-time leader was convicted of orchestrating a government overthrow in September and sentenced more than over two decades in prison, but he continued under house arrest pending appeals.
Top Judicial Official the presiding justice said the action to imprison the septuagenarian politician was a precautionary step after "new facts" emerged.
This included seeking to disable his electronic bracelet and a call for a public vigil that could enable a chance to flee".
Legal Document Reveals Escape Risks
In a filing authorising the detention, the judge said intelligence from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's plan to remove the surveillance device to guarantee victory in his escape.
This, it said, would be "facilitated by the confusion caused by the demonstration called by his offspring.
His child, Flávio Bolsonaro, who serves as a senator, called for a meeting of his backers near Bolsonaro's home to take place on Saturday evening.
The senator wrote on digital networks on Friday: "Are you going to fight for your country, or see it all from your phone there on your settee? I invite you to fight with us."
He said the vigil would be so supporters could "pray for his health and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of the former president's transfer to foreign missions near the home, considering that the probes revealed a history of planning to seek refuge through a consular facility", a statement said.
The judicial paperwork underscores that the United States embassy in the federal district, the capital city, is positioned around approximately 13 kilometers from his dwelling.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow right-wing populist American leader Donald Trump, prompting him to enact a fifty percent tax on imports of Brazilian goods.
The former president is being kept in a federal law enforcement building in Brasilia and will have a imprisonment assessment on the following day.
Recent Legal Requests
It was only on last Friday that the his legal team asked the High Court to permit him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that Bolsonaro be allowed to exit his dwelling for medical care, saying he required regular treatment for lung conditions and other illnesses.
Details of Guilty Verdict
Bolsonaro was found guilty of heading a conspiracy aimed at retaining his authority after he lost the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he had knowledge of a plot which included plans to kill Lula and his VP candidate, Alckmin, and to imprison and murder Justice Moraes - the top judicial official who has been overseeing his judicial proceedings.
The plot was prevented because it didn't receive the endorsement of the army and air force commanders. The current president was inaugurated without problem on the first day of 2023.
But a seven days after, on 8 January, numerous Bolsonaro supporters invaded and destroyed official structures in the national capital, Brazil's capital.
The police intervened and around approximately 1,500 persons were detained.
The judges found that the rioters had been encouraged by Bolsonaro whose plan, they said, was for the country's army to step in, bring back stability and reinstate his authority.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - eight years after the completion of his term.
The former president called the trial a "witch hunt and said it was intended to stop him competing in the next presidential race.
