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 sentenced of orchestrating a armed takeover in last fall and sentenced more than over two decades in incarceration, but he was staying under home detention pending court reviews.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a preventative measure after "new facts" came to light.
This included trying to remove his ankle monitor and a summons to a public vigil that could "allow for a possible escape.
Court Filing Details Flight Fears
In a filing authorising the custody, Justice Moraes said data from the facility tracking the former president's confinement suggested the one-time head of state's plan to remove the surveillance device to ensure success in his flight.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his son.
His son, Flávio Bolsonaro, who serves as a legislator, called for a meeting of his followers near his father's house to take place on Saturday evening.
His son wrote on digital networks on Friday: "Are you going to fight for your country, or observe everything from your mobile device there on your sofa? I call on you to fight with us."
He said the vigil would be so followers could offer prayers for his well-being and for the return of democracy in our nation."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the chance of his move to foreign missions near the home, considering that the investigations revealed a record of organizing to ask for protection through a consular facility", a statement said.
The legal document underscores that the US embassy in the national capital, Brasilia, is located around 13km from his dwelling.
Worldwide Consequences
His judicial problems have provoked anger from fellow right-wing populist US President Trump, leading him to enact a half-rate duty on goods coming from Brazil.
He is being kept in a Federal Police station in Brazil's capital city and will undergo a imprisonment assessment on Sunday.
Latest Court Petitions
It was only on last Friday that the former president's lawyers asked the Supreme Court to permit him to serve his whole jail sentence under house arrest, with digital surveillance.
They also asked that Bolsonaro be allowed to depart his residence for medical treatment, saying he needed ongoing care for respiratory ailments and other ailments.
Details of Guilty Verdict
The former president was convicted of leading a conspiracy aimed at retaining his authority after he failed to win the 2022 election to his left-wing rival, President Lula.
Top judicial officials said that he had knowledge of a plan which involved plans to murder his opponent and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Justice Moraes - the High Court judge who has been presiding over his judicial proceedings.
The scheme was stopped because it couldn't obtain the support of the army and air force commanders. His successor was took office without incident on 1 January 2023.
But a week later, on the eighth of January, numerous his followers stormed and vandalised official structures in the capital, the capital city.
The police 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 plan, they said, was for the national armed forces to step in, restore order and reinstate his authority.
At the moment, the legal team called the over 27-year sentence "absurdly excessive.
He was also banned from campaigning for office until 2060 - eight years after the completion of his term.
The ex-leader called the court case a targeted investigation" and said it was aimed at blocking him participating in the 2026 presidential election.
