Jair Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under home confinement.
The ex-president was sentenced of planning a armed takeover in last fall and given more than 27 years in prison, but he continued under confinement pending court reviews.
High Court Judge Alexandre de Moraes said the action to imprison the 70-year-old politician was a safety action after recent developments were revealed.
This encompassed attempting to break his electronic bracelet and a invitation to a demonstration that could "allow for a possible escape.
Judicial Records Show Flight Fears
In a document approving the detention, Justice Moraes said information from the facility tracking his home detention suggested the former leader's plan to remove the surveillance device to guarantee victory in his getaway".
This, it said, would be assisted by the confusion caused by the demonstration called by his offspring.
His offspring, his son Flávio, who works as a senator, called for a meeting of his supporters near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on the previous day: Do you plan to struggle for your country, or watch it all from your smartphone there on your sofa? I urge you to fight with us."
He said the gathering would be so followers could "pray for his well-being and for the return of democracy in our country."
Diplomatic Refuge Fears
Part of the magistrate's determination was the chance of Bolsonaro's transfer to diplomatic missions near the dwelling, considering that the inquiries revealed a background of organizing to seek refuge through a embassy office", a announcement said.
The court filing emphasizes that the US embassy in the federal district, Brasilia, is positioned around approximately 13 kilometers from the former president's residence.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow populist conservative US President Donald Trump, leading him to implement a fifty percent tax on goods coming from Brazil.
He is being kept in a federal law enforcement building in Brazil's capital city and will undergo a custody hearing on Sunday.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the High Court to allow him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also requested that Bolsonaro be permitted to exit his dwelling for medical treatment, saying he demanded ongoing care for pulmonary infections and other ailments.
Background on Conviction
He was determined responsible of orchestrating a plot aimed at retaining his authority after he was defeated in the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he had knowledge of a plan which involved plans to kill his opponent and his VP candidate, Alckmin, and to imprison and murder Alexandre de Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The scheme was thwarted because it couldn't obtain the support of the army and air force commanders. Lula was took office without problem on 1 January 2023.
But a seven days after, on the eighth of January, numerous his followers stormed and vandalised government buildings in the capital, Brasília.
The law enforcement stepped in and around approximately 1,500 persons were detained.
The magistrates found that the protesters had been encouraged by Bolsonaro whose strategy, they said, was for the national armed forces to intervene, bring back stability and return him to office.
At the moment, his attorneys called the decades-long sentence unreasonably severe".
He was also barred from seeking elected position until the year 2060 - eight years after the conclusion of his imprisonment.
The former president called the court case a targeted investigation" and said it was designed to prevent him running in the 2026 presidential election.
