Bolsonaro has been detained after authorities found he posed a concrete flight risk while under house arrest.
The former head of state was found guilty of orchestrating a government overthrow in last fall and sentenced more than 27 years in jail, but he was staying under home detention pending court reviews.
High Court Judge the presiding justice said the action to imprison the elderly politician was a precautionary step after fresh information emerged.
This included seeking to disable his electronic bracelet and a summons to a public vigil that could facilitate a potential flight.
Legal Document Reveals Escape Risks
In a paperwork permitting the custody, Justice Moraes said data from the centre monitoring his home detention suggested the one-time head of state's aim to disable the surveillance device to guarantee victory in his escape.
This, it said, would be assisted by the confusion caused by the gathering called by his offspring.
His son, Flávio Bolsonaro, who works as a senator, called for a assembly of his followers near his father's house to take place on Saturday night.
The senator wrote on online platforms on Friday: Do you plan to struggle for your nation, or see it all from your mobile device there on your couch? I urge you to struggle with us."
He said the vigil would be so followers could "pray for his physical condition and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the possibility of Bolsonaro's transfer to embassies near the dwelling, considering that the probes revealed a record of organizing to request asylum through a diplomatic representation", a statement said.
The judicial paperwork highlights that the US embassy in the federal district, Brasilia, is positioned around 13km from Bolsonaro's home.
Global Responses
The former president's legal troubles have generated frustration from fellow right-wing populist American leader President Trump, prompting him to enact a fifty percent tax on goods coming from Brazil.
Bolsonaro is being held in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on the following day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to authorize him to serve his whole jail sentence under house arrest, with electronic monitoring.
They also asked that he be authorized to leave his home for healthcare, saying he needed frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
Bolsonaro was found guilty of orchestrating a scheme aimed at maintaining his control after he failed to win the presidential race to his ideological adversary, Lula.
High Court judges said that he had knowledge of a scheme which encompassed plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the High Court judge who has been presiding over Bolsonaro's trial.
The conspiracy was stopped because it couldn't obtain the backing of the army and air force commanders. The current president was took office without incident on January 1st, 2023.
But a seven days after, on January 8th, numerous his followers stormed and vandalised public facilities in the national capital, Brasília.
The police intervened and around 1,500 people were arrested.
The judges found that the protesters had been incited by him whose scheme, they said, was for the Brazilian military to intervene, reestablish control and reinstate his authority.
At the time, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also banned from running for public office until 2060 - eight years later after the conclusion of his imprisonment.
The former president called the court case a targeted investigation" and said it was designed to prevent him running in the next presidential race.
