Jair Bolsonaro has been taken into custody after authorities concluded he posed a definite escape threat while under home confinement.
The one-time leader was convicted of planning a military coup in the ninth month and sentenced more than a 27-year term in jail, but he remained under house arrest pending appeals.
High Court Judge the presiding justice said the move to detain the elderly politician was a precautionary step after fresh information were revealed.
This encompassed trying to remove his electronic bracelet and a call for a supporters' gathering that could facilitate a chance to flee".
In a document approving the custody, Justice Moraes said intelligence from the facility tracking the former president's confinement suggested the former leader's aim to disable the electronic ankle bracelet to guarantee victory in his flight.
This, it said, would be made easier by the confusion caused by the demonstration called by his child.
His offspring, Flávio, who serves as a legislator, called for a meeting of his supporters near Bolsonaro's home to take place on Saturday evening.
The senator wrote on social media on Friday: "Are you going to fight for your nation, or watch it all from your mobile device there on your sofa? I call on you to fight with us."
He said the gathering would be so backers could offer prayers for his well-being and for the reestablishment of democratic governance in our country."
Part of Justice Moraes's determination was the chance of Bolsonaro's move to embassies near the dwelling, considering that the investigations revealed a background of organizing to ask for protection through a embassy office", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the national capital, Brasilia, is situated around approximately 13 kilometers from the former president's residence.
The former president's legal troubles have generated frustration from fellow right-wing populist American leader Donald Trump, prompting him to impose a fifty percent tax on Brazilian product imports.
Bolsonaro is being detained in a national police facility in the capital and will undergo a detention review on Sunday.
It was only on last Friday that the ex-leader's attorneys asked the High Court to authorize him to serve his whole jail sentence under home confinement, with digital surveillance.
They also petitioned that the former president be authorized to exit his dwelling for medical care, saying he required regular treatment for pulmonary infections and other health problems.
He was convicted of heading a plot aimed at keeping him in power after he was defeated in the presidential race to his political opponent, Lula.
Top judicial officials said that he had knowledge of a plot which included plans to assassinate the current president and his VP candidate, Alckmin, and to detain and kill the presiding judge - the top judicial official who has been managing the former president's case.
The conspiracy was stopped because it failed to get the backing of the army and air force commanders. His successor was inaugurated without problem on 1 January 2023.
But a week later, on January 8th, many Bolsonaro supporters invaded and destroyed government buildings in the capital, BrasÃlia.
The law enforcement took action and around approximately 1,500 persons were arrested.
The justices found that the demonstrators had been incited by the former president whose scheme, they said, was for the national armed forces to step in, reestablish control and reinstate his authority.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also prohibited from seeking elected position until twenty-sixty - eight years later after the end of his sentence.
The former president called the court case a political persecution and said it was designed to prevent him participating in the 2026 presidential election.
