The former Brazilian leader has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The one-time leader was convicted of planning a military coup in last fall and sentenced more than 27 years in prison, but he remained under home detention pending court reviews.
High Court Judge Alexandre de Moraes said the action to imprison the septuagenarian politician was a safety action after recent developments emerged.
This encompassed seeking to disable his ankle monitor and a invitation to a public vigil that could facilitate a potential flight.
Legal Document Reveals Escape Concerns
In a paperwork permitting the arrest, the magistrate said intelligence from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be "facilitated by the chaos caused by the demonstration called by his child.
His son, his son Flávio, who holds office as a congressional representative, called for a assembly of his followers near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your country, or see it all from your smartphone there on your couch? I invite you to fight with us."
He said the gathering would be so backers could "pray for his physical condition and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the possibility of his transfer to diplomatic missions near the residence, considering that the inquiries revealed a record of arranging to ask for protection through a embassy office", a announcement said.
The judicial paperwork underscores that the United States embassy in the national capital, the capital city, is located around 13km from his dwelling.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow populist conservative US President Donald Trump, prompting him to implement a fifty percent tax on Brazilian product imports.
The former president is being detained in a Federal Police station in Brazil's capital city and will undergo a detention review on the next day.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the Top Court to permit him to serve his whole jail sentence under domestic detention, with tracking devices.
They also requested that Bolsonaro be authorized to exit his dwelling for healthcare, saying he required frequent medical attention for pulmonary infections and other ailments.
Details of Guilty Verdict
He was found guilty of heading a scheme aimed at keeping him in power after he failed to win the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he had knowledge of a plot which encompassed plans to kill his opponent and his running partner, Geraldo Alckmin, and to arrest and execute Justice Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The scheme was prevented because it didn't receive the backing of the armed forces officials. Lula was inaugurated without issue on 1 January 2023.
But a following week, on January 8th, many Bolsonaro supporters invaded and destroyed government buildings in the capital, Brasília.
The security forces stepped in and around 1,500 people were arrested.
The justices found that the protesters had been encouraged by him whose strategy, they said, was for the national armed forces to take action, reestablish control and reinstate his authority.
At the period, the legal team called the 27 years and three months sentence extremely harsh.
He was also banned from running for public office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The former president called the court case a political persecution and said it was aimed at blocking him running in the 2026 national vote.
