Jair Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under house arrest.
The ex-president was found guilty of planning a military coup in last fall and given more than over two decades in jail, but he continued under confinement pending court reviews.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the 70-year-old politician was a precautionary step after "new facts" were revealed.
This encompassed attempting to break his ankle monitor and a call for a demonstration that could facilitate a potential flight.
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the magistrate said data from the centre monitoring his home detention suggested the ex-president's plan to remove the surveillance device to secure accomplishment in his flight.
This, it said, would be made easier by the confusion caused by the protest called by his child.
His child, Flávio, who holds office as a senator, called for a assembly of his backers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your nation, or see it all from your smartphone there on your sofa? I call on you to fight with us."
He said the demonstration would be so supporters could offer prayers for his well-being and for the return of democracy in our country."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the chance of Bolsonaro's transfer to embassies near the dwelling, considering that the investigations revealed a history of organizing to request asylum through a diplomatic representation", a announcement said.
The judicial paperwork emphasizes that the American diplomatic mission in the capital, Brasilia, is situated around 8 miles from his dwelling.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow populist conservative US President President Trump, causing him to implement a half-rate duty on Brazilian product imports.
Bolsonaro is being held in a federal law enforcement building in the capital and will have a custody hearing on the next day.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the Top Court to authorize him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also petitioned that he be authorized to depart his residence for medical care, saying he required frequent medical attention for respiratory ailments and other illnesses.
Background on Conviction
Bolsonaro was determined responsible of leading a scheme aimed at maintaining his control after he lost the presidential race to his ideological adversary, Lula.
High Court judges said that he knew of a plan which encompassed plans to murder his opponent and his running partner, Alckmin, and to detain and kill the presiding judge - the Supreme Court justice who has been presiding over his judicial proceedings.
The plot was prevented because it didn't receive the support of the army and air force commanders. His successor was sworn in without incident on 1 January 2023.
But a seven days after, on January 8th, thousands of his backers invaded and destroyed government buildings in the capital, Brazil's capital.
The law enforcement took action and around fifteen hundred individuals were taken into custody.
The magistrates found that the rioters had been encouraged by him whose scheme, they said, was for the national armed forces to intervene, bring back stability and return him to office.
At the period, the legal team called the 27 years and three months sentence unreasonably severe".
He was also prohibited from running for public office until the year 2060 - eight years later after the completion of his term.
The former president called the court case a political persecution and said it was aimed at blocking him participating in the 2026 national vote.
