Jair Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under home confinement.
The one-time leader was found guilty of orchestrating a military coup in September and given more than over two decades in prison, but he continued under confinement pending appeals.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a safety action after "new facts" came to light.
This involved trying to remove his ankle monitor and a summons to a supporters' gathering that could enable a possible escape.
Judicial Records Show Escape Concerns
In a filing authorising the custody, the judge said intelligence from the facility tracking his home detention suggested the former leader's aim to disable the tracking monitor to guarantee victory in his escape.
This, it said, would be assisted by the disorder caused by the protest called by his offspring.
His offspring, his son Flávio, who holds office as a legislator, called for a assembly of his followers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on online platforms on the previous day: Do you plan to struggle for your nation, or observe everything from your mobile device there on your sofa? I call on you to battle with us."
He said the gathering would be so supporters could "pray for his well-being and for the return of democracy in our nation."
Foreign Shelter Risks
Part of the judge's determination was the possibility of the former president's transfer to diplomatic missions near the dwelling, considering that the inquiries revealed a background of organizing to request asylum through a consular facility", a announcement said.
The judicial paperwork underscores that the American diplomatic mission in the federal district, Brasilia, is located around 13km from Bolsonaro's home.
International Reactions
The former president's legal troubles have generated frustration from fellow right-wing populist American leader Donald Trump, leading him to impose a half-rate duty on imports of Brazilian goods.
The former president is being kept in a federal law enforcement building in Brazil's capital city and will have a detention review on the next day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the High Court to authorize him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that the former president be authorized to exit his dwelling for medical care, saying he required frequent medical attention for respiratory ailments and other ailments.
Context of Sentencing
Bolsonaro was found guilty of heading a plot aimed at keeping him in power after he lost the 2022 election to his political opponent, President Lula.
Top judicial officials said that he had knowledge of a plot which included plans to murder Lula and his running partner, Geraldo Alckmin, and to detain and kill the presiding judge - the Supreme Court justice who has been overseeing his judicial proceedings.
The conspiracy was stopped because it failed to get the support of the military leaders. Lula was took office without issue on January 1st, 2023.
But a following week, on 8 January, numerous Bolsonaro supporters invaded and destroyed public facilities in the federal district, the capital city.
The police intervened and around fifteen hundred individuals were arrested.
The magistrates found that the rioters had been incited by the former president whose plan, they said, was for the country's army to intervene, restore order and return him to office.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also prohibited from campaigning for office until twenty-sixty - a decade minus two years after the completion of his term.
The one-time head of state called the court case a targeted investigation" and said it was intended to stop him participating in the next presidential race.
