Jair Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under home confinement.
The one-time leader was sentenced of orchestrating a government overthrow in September and handed more than 27 years in incarceration, but he remained under home detention pending court reviews.
High Court Judge the presiding justice said the action to imprison the 70-year-old politician was a safety action after recent developments emerged.
This encompassed trying to remove his ankle monitor and a call for a supporters' gathering that could facilitate a potential flight.
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, Justice Moraes said information from the facility tracking the former president's confinement suggested the one-time head of state's "intention to break the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be made easier by the disorder caused by the protest called by his child.
His offspring, Flávio, who serves as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on digital networks on Friday: Will you battle for your country, or see it all from your smartphone there on your settee? I urge you to battle with us."
He said the vigil would be so followers could "pray for his well-being and for the restoration of democratic rule in our land."
Diplomatic Refuge Fears
Part of the magistrate's decision was the potential of Bolsonaro's move to diplomatic missions near the dwelling, considering that the investigations revealed a history of arranging to seek refuge through a diplomatic representation", a statement said.
The judicial paperwork highlights that the United States embassy in the federal district, Brasilia, is situated around 8 miles from the former president's residence.
International Reactions
His judicial problems have provoked anger from fellow conservative nationalist US President Donald Trump, causing him to implement a 50% tariff on goods coming from Brazil.
The former president is being held in a federal law enforcement building in the capital and will have a detention review on the following day.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the High Court to authorize him to serve his whole jail sentence under house arrest, with digital surveillance.
They also requested that the former president be permitted to exit his dwelling for healthcare, saying he demanded frequent medical attention for lung conditions and other health problems.
Details of Guilty Verdict
Bolsonaro was convicted of leading a plot aimed at maintaining his control after he was defeated in the presidential race to his left-wing rival, President Lula.
High Court judges said that he knew of a plan which involved plans to kill his opponent and his running partner, Alckmin, and to arrest and execute Justice Moraes - the top judicial official who has been overseeing his judicial proceedings.
The plot was stopped because it didn't receive the support of the army and air force commanders. The current president was took office without incident on the first day of 2023.
But a following week, on the eighth of January, thousands of his backers invaded and destroyed official structures in the national capital, Brazil's capital.
The security forces stepped in and around approximately 1,500 persons were detained.
The magistrates found that the protesters had been incited by him whose strategy, they said, was for the Brazilian military to take action, bring back stability and bring him back to power.
At the period, the legal team called the decades-long sentence unreasonably severe".
He was also banned from running for public office until 2060 - eight years later after the conclusion of his imprisonment.
The former president called the trial a targeted investigation" and said it was designed to prevent him running in the next presidential race.
