The former Brazilian leader has been arrested after authorities determined he posed a definite escape threat while under house arrest.
The ex-president was convicted of orchestrating a military coup in the ninth month and given more than a 27-year term in incarceration, but he remained under confinement pending appeals.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the septuagenarian politician was a safety action after recent developments emerged.
This encompassed attempting to break his ankle monitor and a summons to a public vigil that could facilitate a potential flight.
Court Filing Details Flight Fears
In a paperwork permitting the detention, the magistrate said information from the centre monitoring Bolsonaro's house arrest suggested the ex-president's aim to disable the tracking monitor to secure accomplishment in his escape.
This, it said, would be made easier by the chaos caused by the demonstration called by his child.
His son, Flávio Bolsonaro, who serves as a legislator, called for a gathering of his followers near the former president's residence to take place on Saturday evening.
The senator wrote on digital networks on the previous day: Will you battle for your country, or observe everything from your phone there on your settee? I invite you to struggle with us."
He said the vigil would be so backers could "pray for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the possibility of his move to embassies near the residence, considering that the inquiries revealed a history of arranging to ask for protection through a diplomatic representation", a statement said.
The court filing highlights that the US embassy in the national capital, Brasilia, is positioned around 13km from Bolsonaro's home.
International Reactions
His judicial problems have generated frustration from fellow right-wing populist United States President Trump, leading him to implement a fifty percent tax on imports of Brazilian goods.
He is being detained in a federal law enforcement building in Brasilia and will experience a custody hearing on the next day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the High Court to authorize him to serve his whole jail sentence under house arrest, with tracking devices.
They also asked that Bolsonaro be permitted to exit his dwelling for healthcare, saying he required frequent medical attention for pulmonary infections and other health problems.
Details of Guilty Verdict
The former president was found guilty of leading a plot aimed at keeping him in power after he was defeated in the presidential race to his ideological adversary, President Lula.
Top judicial officials said that he knew of a plan which included plans to murder his opponent and his VP candidate, Alckmin, and to imprison and murder Justice Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The plot was prevented because it didn't receive the backing of the armed forces officials. His successor was inaugurated without issue on 1 January 2023.
But a following week, on the eighth of January, many his backers stormed and vandalised public facilities in the national capital, Brasília.
The security forces took action and around fifteen hundred individuals were detained.
The magistrates found that the demonstrators had been provoked by Bolsonaro whose strategy, they said, was for the national armed forces to step in, restore order and bring him back to power.
At the moment, the legal team called the over 27-year sentence unreasonably severe".
He was also barred from seeking elected position until the year 2060 - a decade minus two years after the completion of his term.
The ex-leader called the legal proceedings a "witch hunt and said it was aimed at blocking him running in the 2026 national vote.
