The former Brazilian leader has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The one-time leader was sentenced of planning a armed takeover in September and given more than 27 years in incarceration, but he was staying under home detention pending legal challenges.
High Court Judge Justice Moraes said the action to imprison the 70-year-old politician was a precautionary step after recent developments emerged.
This involved attempting to break his ankle monitor and a invitation to a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Flight Fears
In a paperwork permitting the arrest, the judge said information from the centre monitoring the former president's confinement suggested the ex-president's plan to remove the tracking monitor to ensure success in his flight.
This, it said, would be "facilitated by the chaos caused by the protest called by his child.
His offspring, Flávio, who works as a legislator, called for a gathering of his supporters near his father's house to take place on the weekend.
His son wrote on social media on last Friday: Do you plan to struggle for your country, or watch it all from your mobile device there on your settee? I call on you to battle with us."
He said the vigil would be so supporters could offer prayers for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the judge's ruling was the chance of his "relocation to diplomatic missions near the home, considering that the investigations revealed a history of planning to ask for protection through a diplomatic representation", a announcement said.
The legal document highlights that the US embassy in the national capital, Brasilia, is located around 8 miles from the former president's residence.
Worldwide Consequences
The former president's legal troubles have generated frustration from fellow populist conservative United States President Donald Trump, leading him to enact a half-rate duty on Brazilian product imports.
He is being held in a national police facility in the capital and will undergo a detention review on the next day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the High Court to permit him to serve his whole jail sentence under house arrest, with digital surveillance.
They also requested that he be permitted to leave his home for medical treatment, saying he demanded regular treatment for lung conditions and other illnesses.
Details of Guilty Verdict
Bolsonaro was found guilty of leading a scheme aimed at maintaining his control after he failed to win the national vote to his ideological adversary, Lula.
Supreme Court justices said that he was aware of a scheme which included plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute the presiding judge - the top judicial official who has been overseeing his judicial proceedings.
The scheme was thwarted because it failed to get the support of the armed forces officials. The current president was sworn in without issue on the first day of 2023.
But a following week, on January 8th, numerous his followers invaded and destroyed government buildings in the capital, Brasília.
The police stepped in and around approximately 1,500 persons were taken into custody.
The magistrates found that the demonstrators had been encouraged by the former president whose plan, they said, was for the Brazilian military to step in, bring back stability 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 running for public office until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a political persecution and said it was aimed at blocking him competing in the 2026 presidential election.
