Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under domestic detention.
The one-time leader was sentenced of plotting a armed takeover in September and given more than over two decades in jail, but he was staying under home detention pending court reviews.
Top Judicial Official Alexandre de Moraes said the decision to arrest the septuagenarian politician was a preventative measure after recent developments came to light.
This involved seeking to disable his tracking device and a call for a public vigil that could "allow for a possible escape.
Judicial Records Show Escape Risks
In a filing authorising the detention, the judge said intelligence from the unit overseeing Bolsonaro's house arrest suggested the ex-president's "intention to break the tracking monitor to secure accomplishment in his flight.
This, it said, would be made easier by the confusion caused by the demonstration called by his son.
His offspring, his son Flávio, who works as a congressional representative, called for a assembly of his supporters near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on the previous day: Will you battle for your country, or see it all from your smartphone there on your sofa? I urge you to fight with us."
He said the gathering would be so supporters could seek divine intervention for his well-being and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the chance of Bolsonaro's transfer to diplomatic missions near the home, considering that the probes revealed a history of arranging to request asylum through a diplomatic representation", a statement said.
The judicial paperwork highlights that the US embassy in the capital, the capital city, is located around 8 miles from Bolsonaro's home.
Global Responses
The former president's legal troubles have drawn the ire of fellow conservative nationalist American leader President Trump, leading 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 custody hearing on the next day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to permit him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also asked that Bolsonaro be allowed to leave his home for medical treatment, saying he demanded regular treatment for respiratory ailments and other health problems.
Details of Guilty Verdict
He was convicted of leading a scheme aimed at retaining his authority after he was defeated in the national vote to his political opponent, Lula.
Top judicial officials said that he knew of a scheme which included plans to murder his opponent and his VP candidate, his vice-presidential candidate, and to imprison and murder the presiding judge - the Supreme Court justice who has been overseeing his judicial proceedings.
The scheme was thwarted because it didn't receive the backing of the army and air force commanders. The current president was sworn in without problem on 1 January 2023.
But a seven days after, on the eighth of January, thousands of his backers attacked and damaged public facilities in the national capital, the capital city.
The security forces took action and around approximately 1,500 persons were arrested.
The magistrates found that the protesters had been incited by him whose scheme, they said, was for the Brazilian military to take action, bring back stability and return him to office.
At the moment, the legal team called the over 27-year sentence "absurdly excessive.
He was also banned from seeking elected position until twenty-sixty - a decade minus two years after the conclusion of his imprisonment.
The one-time head of state called the trial a targeted investigation" and said it was designed to prevent him competing in the 2026 national vote.
