Bolsonaro has been detained after authorities found he posed a serious risk of fleeing while under home confinement.
The one-time leader was found guilty of planning a military coup in the ninth month and given more than 27 years in prison, but he continued under confinement pending court reviews.
High Court Judge the presiding justice said the move to detain the elderly politician was a safety action after fresh information emerged.
This involved trying to remove his electronic bracelet and a call for a demonstration that could enable a chance to flee".
Legal Document Reveals Escape Concerns
In a paperwork permitting the detention, the judge said intelligence from the centre monitoring the former president's confinement suggested the ex-president's aim to disable the surveillance device to ensure success in his getaway".
This, it said, would be "facilitated by the confusion caused by the protest called by his offspring.
His offspring, Flávio, who works as a legislator, 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 the previous day: Will you battle for your nation, or watch it all from your mobile device there on your couch? I call on you to struggle with us."
He said the demonstration would be so supporters 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 chance of Bolsonaro's transfer to embassies near the dwelling, considering that the probes revealed a history of planning to request asylum through a diplomatic representation", a announcement said.
The court filing underscores that the US embassy in the capital, Brasilia, is located around 13km from his dwelling.
International Reactions
The former president's legal troubles have drawn the ire of fellow right-wing populist American leader President Trump, leading him to impose a 50% tariff on imports of Brazilian goods.
He is being kept in a Federal Police station in the capital and will have a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the High Court to permit him to serve his whole jail sentence under house arrest, with electronic monitoring.
They also requested that he be allowed to depart his residence for healthcare, saying he demanded ongoing care for pulmonary infections and other ailments.
Context of Sentencing
Bolsonaro was convicted of heading a scheme aimed at maintaining his control after he was defeated in the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plan which included plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Justice Moraes - the top judicial official who has been overseeing his judicial proceedings.
The scheme was stopped because it couldn't obtain the support of the army and air force commanders. The current president was inaugurated without problem on 1 January 2023.
But a week later, on the eighth of January, many Bolsonaro supporters invaded and destroyed government buildings in the capital, Brasília.
The security forces took action and around approximately 1,500 persons were taken into custody.
The magistrates found that the rioters had been encouraged by him whose strategy, they said, was for the country's army to step in, restore order and reinstate his authority.
At the time, the legal team called the over 27-year sentence unreasonably severe".
He was also barred from seeking elected position until 2060 - eight years after the completion of his term.
The former president called the legal proceedings a political persecution and said it was designed to prevent him participating in the 2026 presidential election.
