The former Brazilian leader has been detained after authorities concluded he posed a concrete flight risk while under house arrest.
The one-time leader was sentenced of planning a armed takeover in September and sentenced more than a 27-year term in jail, but he continued under confinement pending appeals.
High Court Judge Alexandre de Moraes said the action to imprison the elderly politician was a precautionary step after "new facts" were revealed.
This involved seeking to disable his ankle monitor and a summons to a demonstration that could facilitate a potential flight.
Judicial Records Show Escape Concerns
In a filing authorising the detention, the magistrate said intelligence from the facility tracking Bolsonaro's house arrest suggested the one-time head of state's "intention to break the tracking monitor to guarantee victory in his flight.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his offspring.
His son, Flávio, who works as a legislator, called for a meeting of his supporters near his father's house to take place on Saturday evening.
The senator wrote on social media on Friday: Do you plan to struggle for your country, or observe everything from your mobile device there on your sofa? I call on you to battle with us."
He said the demonstration would be so supporters could "pray for his health and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of Justice Moraes's decision was the chance of the former president's transfer to diplomatic missions near the dwelling, considering that the probes revealed a record of arranging to ask for protection through a consular facility", a statement said.
The legal document highlights that the American diplomatic mission in the capital, Brazil's capital, is positioned around approximately 13 kilometers from Bolsonaro's home.
Global Responses
His judicial problems have drawn the ire of fellow conservative nationalist American leader Trump, leading him to enact a fifty percent tax on goods coming from Brazil.
He is being detained in a federal law enforcement building in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the High Court to permit him to complete his entire prison term under domestic detention, with digital surveillance.
They also petitioned that Bolsonaro be allowed to leave his home for medical care, saying he required frequent medical attention for respiratory ailments and other illnesses.
Background on Conviction
Bolsonaro was convicted of leading a scheme aimed at retaining his authority after he lost the presidential race to his left-wing rival, President Lula.
High Court judges said that he was aware of a plan which included plans to murder the current president and his running partner, his vice-presidential candidate, and to arrest and execute Justice Moraes - the High Court judge who has been managing the former president's case.
The conspiracy was prevented because it failed to get the support of the military leaders. The current president was took office without problem on 1 January 2023.
But a following week, on the eighth of January, numerous Bolsonaro supporters stormed and vandalised government buildings in the national capital, Brazil's capital.
The security forces stepped in and around approximately 1,500 persons were taken into custody.
The judges found that the protesters had been provoked by the former president whose plan, they said, was for the country's army to step in, bring back stability and return him to office.
At the moment, the legal team called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until 2060 - a decade minus two years after the conclusion of his imprisonment.
The one-time head of state called the court case a "witch hunt and said it was designed to prevent him running in the 2026 presidential election.
