Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under home confinement.
The one-time leader was convicted of orchestrating a government overthrow in the ninth month and given more than over two decades in jail, but he remained under confinement pending court reviews.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a precautionary step after recent developments came to light.
This included trying to remove his electronic bracelet and a call for a demonstration that could enable a potential flight.
Court Filing Details Escape Concerns
In a document approving the arrest, Justice Moraes said information from the facility tracking the former president's confinement suggested the one-time head of state's aim to disable the tracking monitor to ensure success in his escape.
This, it said, would be assisted by the confusion caused by the gathering called by his son.
His son, his son Flávio, who holds office as a congressional representative, called for a assembly of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on Friday: "Are you going to fight for your country, or watch it all from your phone there on your sofa? I urge you to fight with us."
He said the vigil would be so backers could offer prayers for his physical condition and for the reestablishment of democratic governance in our country."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the possibility of the former president's transfer to foreign missions near the dwelling, considering that the inquiries revealed a background of arranging to ask for protection through a embassy office", a declaration said.
The court filing emphasizes that the American diplomatic mission in the capital, the capital city, is situated around approximately 13 kilometers from Bolsonaro's home.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist American leader Trump, leading him to enact a half-rate duty on goods coming from Brazil.
The former president is being held 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 Friday that the his legal team asked the High Court to permit him to complete his entire prison term under house arrest, with digital surveillance.
They also asked that he be authorized to exit his dwelling for medical treatment, saying he needed frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
The former president was found guilty of leading a plot aimed at maintaining his control after he failed to win the presidential race to his left-wing rival, President Lula.
Supreme Court justices said that he was aware of a scheme which included plans to assassinate the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the top judicial official who has been overseeing his judicial proceedings.
The conspiracy was prevented because it failed to get the endorsement of the armed forces officials. The current president was took office without issue on the first day of 2023.
But a week later, on the eighth of January, thousands of Bolsonaro supporters invaded and destroyed public facilities in the national capital, Brasília.
The law enforcement took action and around 1,500 people were taken into custody.
The justices found that the rioters had been incited by the former president whose strategy, they said, was for the national armed forces to step in, bring back stability and bring him back to power.
At the period, the legal team called the decades-long sentence "absurdly excessive.
He was also banned from running for public office until twenty-sixty - eight years after the completion of his term.
The ex-leader called the legal proceedings a political persecution and said it was designed to prevent him running in the 2026 presidential election.
