Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of orchestrating a military coup in last fall and handed more than over two decades in incarceration, but he remained under confinement pending legal challenges.
Top Judicial Official the presiding justice said the action to imprison the 70-year-old politician was a preventative measure after recent developments emerged.
This encompassed trying to remove his ankle monitor and a call for a public vigil that could enable a possible escape.
Judicial Records Show Escape Concerns
In a paperwork permitting the custody, the judge said intelligence from the unit overseeing the former president's confinement suggested the former leader's aim to disable the tracking monitor to ensure success in his flight.
This, it said, would be made easier by the confusion caused by the gathering called by his offspring.
His offspring, his son Flávio, who serves as a legislator, called for a gathering of his supporters near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Will you battle for your nation, or observe everything from your mobile device there on your couch? I invite you to struggle with us."
He said the demonstration would be so backers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of the magistrate's decision was the potential of Bolsonaro's transfer to diplomatic missions near the residence, considering that the probes revealed a record of arranging to ask for protection through a consular facility", a statement said.
The legal document underscores that the US embassy in the capital, Brazil's capital, is located around 13km from his dwelling.
Global Responses
The former president's legal troubles have drawn the ire of fellow right-wing populist US President President Trump, causing him to enact a half-rate duty on goods coming from Brazil.
The former president is being held in a Federal Police station in the capital and will undergo a imprisonment assessment on the next day.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the High Court to allow him to complete his entire prison term under house arrest, with electronic monitoring.
They also petitioned that Bolsonaro be permitted to depart his residence for medical care, saying he required regular treatment for pulmonary infections and other illnesses.
Context of Sentencing
Bolsonaro was convicted of leading a scheme aimed at maintaining his control after he failed to win the 2022 election to his political opponent, Lula.
Supreme Court justices said that he had knowledge of a scheme which involved plans to assassinate the current president and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been overseeing the former president's case.
The plot was prevented because it didn't receive the backing of the military leaders. His successor was took office without issue on the first day of 2023.
But a following week, on 8 January, thousands of Bolsonaro supporters attacked and damaged public facilities in the federal district, the capital city.
The security forces took action and around fifteen hundred individuals were detained.
The judges found that the rioters had been incited by the former president whose scheme, they said, was for the country's army to step in, bring back stability and return him to office.
At the period, his attorneys called the over 27-year sentence unreasonably severe".
He was also barred from running for public office until twenty-sixty - eight years after the completion of his term.
The ex-leader called the legal proceedings a political persecution and said it was intended to stop him competing in the 2026 national vote.
