Jair Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under domestic detention.
The ex-president was convicted of orchestrating a government overthrow in September and given more than a 27-year term in incarceration, but he was staying under home detention pending appeals.
Top Judicial Official Justice Moraes said the action to imprison the septuagenarian politician was a preventative measure after fresh information came to light.
This involved attempting to break his electronic bracelet and a summons to a supporters' gathering that could enable a chance to flee".
Legal Document Reveals Escape Risks
In a document approving the detention, the judge said intelligence from the unit overseeing Bolsonaro's house arrest suggested the one-time head of state's "intention to break the surveillance device to secure accomplishment in his flight.
This, it said, would be made easier by the confusion caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who works as a congressional representative, called for a assembly of his backers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on the previous day: Do you plan to struggle for your homeland, or watch it all from your mobile device there on your settee? I call on you to fight with us."
He said the vigil would be so followers could offer prayers for his health and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of the judge's decision was the chance of Bolsonaro's "relocation to diplomatic missions near the dwelling, considering that the probes revealed a background of arranging to seek refuge through a embassy office", a announcement said.
The judicial paperwork highlights that the American diplomatic mission in the national capital, Brasilia, is situated around 8 miles from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow populist conservative US President Donald Trump, leading him to enact a half-rate duty on goods coming from Brazil.
He is being held in a Federal Police station in Brasilia and will have a detention review on Sunday.
Recent Legal Requests
It was only on Friday that the his legal team asked the High Court to authorize him to fulfill his full incarceration period under house arrest, with tracking devices.
They also petitioned that he be authorized to exit his dwelling for medical treatment, saying he required regular treatment for lung conditions and other health problems.
Context of Sentencing
He was found guilty of heading a scheme aimed at keeping him in power after he lost the presidential race to his ideological adversary, President Lula.
High Court judges said that he knew of a plot which included plans to murder his opponent and his VP candidate, Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been presiding over the former president's case.
The conspiracy was thwarted because it didn't receive the endorsement of the armed forces officials. Lula was sworn in without problem on January 1st, 2023.
But a week later, on 8 January, many his backers invaded and destroyed government buildings in the federal district, Brazil's capital.
The security forces took action and around fifteen hundred individuals were detained.
The magistrates found that the rioters had been encouraged by the former president whose plan, they said, was for the Brazilian military to take action, bring back stability and reinstate his authority.
At the period, the legal team called the 27 years and three months sentence extremely harsh.
He was also banned from seeking elected position until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the court case a political persecution and said it was designed to prevent him running in the next presidential race.
