Bolsonaro has been taken into custody after authorities concluded he posed a definite escape threat while under home confinement.
The one-time leader was found guilty of planning a armed takeover in last fall and given more than over two decades in jail, but he continued under home detention pending legal challenges.
Top Judicial Official Justice Moraes said the move to detain the 70-year-old politician was a precautionary step after recent developments emerged.
This included trying to remove his electronic bracelet and a call for a supporters' gathering that could enable a possible escape.
Judicial Records Show Escape Risks
In a document approving the custody, Justice Moraes said intelligence from the centre monitoring Bolsonaro's house arrest suggested the former leader's "intention to break the surveillance device to ensure success in his getaway".
This, it said, would be assisted by the confusion caused by the protest called by his child.
His son, Flávio, who works as a legislator, called for a gathering of his followers near the former president's residence to take place on the weekend.
His son wrote on online platforms on Friday: Do you plan to struggle for your nation, or watch it all from your smartphone there on your couch? I invite you to battle with us."
He said the gathering would be so backers could seek divine intervention for his physical condition and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of the magistrate's determination was the potential of the former president's move to diplomatic missions near the dwelling, considering that the probes revealed a history of arranging to request asylum through a diplomatic representation", a announcement said.
The legal document highlights that the American diplomatic mission in the national capital, the capital city, is positioned around 8 miles from the former president's residence.
Global Responses
The former president's legal troubles have generated frustration from fellow conservative nationalist United States President President Trump, causing him to impose a half-rate duty on Brazilian product imports.
He is being kept in a national police facility in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the Top Court to allow him to complete his entire prison term under home confinement, with digital surveillance.
They also requested that he be permitted to exit his dwelling for medical care, saying he needed frequent medical attention for lung conditions and other health problems.
Background on Conviction
Bolsonaro was convicted of orchestrating a scheme aimed at retaining his authority after he lost the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a plan which involved plans to assassinate his opponent and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Alexandre de Moraes - the High Court judge who has been managing his judicial proceedings.
The scheme was prevented because it failed to get the backing of the armed forces officials. Lula was sworn in without problem on January 1st, 2023.
But a following week, on the eighth of January, numerous Bolsonaro supporters attacked and damaged government buildings in the capital, the capital city.
The law enforcement took action and around 1,500 people were detained.
The justices found that the demonstrators had been provoked by the former president whose scheme, they said, was for the national armed forces to take action, restore order and reinstate his authority.
At the time, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until 2060 - a decade minus two years after the end of his sentence.
The ex-leader called the court case a "witch hunt and said it was designed to prevent him participating in the 2026 presidential election.
