Bolsonaro has been taken into custody after authorities concluded he posed a definite escape threat while under house arrest.
The former head of state was sentenced of orchestrating a armed takeover in last fall and handed more than 27 years in prison, but he was staying under home detention pending legal challenges.
Top Judicial Official Justice Moraes said the decision to arrest the septuagenarian politician was a precautionary step after recent developments emerged.
This involved attempting to break his electronic bracelet and a invitation to a public vigil that could facilitate a possible escape.
Judicial Records Show Escape Risks
In a document approving the custody, Justice Moraes said intelligence from the centre monitoring his home detention suggested the ex-president's plan to remove the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be "facilitated by the chaos caused by the protest called by his child.
His offspring, his son Flávio, who holds office as a congressional representative, called for a gathering of his followers near his father's house to take place on the weekend.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your nation, or watch it all from your smartphone there on your settee? I invite you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his health and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the potential of his move to foreign missions near the home, considering that the inquiries revealed a record of arranging to request asylum through a consular facility", a announcement said.
The legal document underscores that the American diplomatic mission in the national capital, the capital city, is situated around 8 miles from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow conservative nationalist American leader President Trump, prompting him to impose a 50% tariff on imports of Brazilian goods.
He is being kept in a federal law enforcement building in the capital and will experience a custody hearing on the next day.
Recent Legal Requests
It was only on the previous day that the ex-leader's attorneys asked the High Court to permit him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also asked that he be authorized to leave his home for medical care, saying he demanded regular treatment for lung conditions and other ailments.
Details of Guilty Verdict
He was convicted of orchestrating a scheme aimed at keeping him in power after he was defeated in the 2022 election to his political opponent, Lula.
Top judicial officials said that he knew of a plot which involved plans to assassinate Lula and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been presiding over his judicial proceedings.
The conspiracy was prevented because it didn't receive the endorsement of the armed forces officials. His successor was inaugurated without problem on January 1st, 2023.
But a seven days after, on the eighth of January, numerous his backers invaded and destroyed government buildings in the capital, Brasília.
The security forces stepped in and around fifteen hundred individuals were taken into custody.
The justices found that the demonstrators had been provoked by him whose scheme, they said, was for the Brazilian military to take action, restore order and bring him back to power.
At the period, Bolsonaro's lawyers called the 27 years and three months sentence "absurdly excessive.
He was also barred from running for public office until twenty-sixty - a decade minus two years after the conclusion of his imprisonment.
The ex-leader called the court case a political persecution and said it was intended to stop him running in the 2026 presidential election.
