Bolsonaro has been detained after authorities found he posed a definite escape threat while under domestic detention.
The ex-president was sentenced of orchestrating a armed takeover in the ninth month and handed more than over two decades in incarceration, but he was staying under home detention pending appeals.
Top Judicial Official Justice Moraes said the move to detain the elderly politician was a preventative measure after fresh information came to light.
This encompassed attempting to break his ankle monitor and a invitation to a public vigil that could enable a chance to flee".
Court Filing Details Flight Fears
In a paperwork permitting the custody, the magistrate said information from the centre monitoring his home detention suggested the former leader's aim to disable the tracking monitor to secure accomplishment in his getaway".
This, it said, would be made easier by the chaos caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who holds office as a legislator, called for a meeting of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on last Friday: "Are you going to fight for your homeland, or watch it all from your mobile device there on your couch? I invite you to struggle with us."
He said the vigil would be so backers could "pray for his health and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of the judge's ruling was the possibility of Bolsonaro's "relocation to embassies near the residence, considering that the inquiries revealed a history of arranging to ask for protection through a embassy office", a declaration said.
The judicial paperwork highlights that the US embassy in the federal district, Brasilia, is situated around approximately 13 kilometers from his dwelling.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow populist conservative US President President Trump, prompting him to implement a 50% tariff on Brazilian product imports.
He is being held in a national police facility in Brazil's capital city and will undergo a custody hearing on the following day.
Latest Court Petitions
It was only on last Friday that the former president's lawyers asked the High Court to allow him to complete his entire prison term under home confinement, with tracking devices.
They also petitioned that the former president be authorized to depart his residence for medical treatment, saying he demanded frequent medical attention for pulmonary infections and other health problems.
Context of Sentencing
The former president was determined responsible of leading a scheme 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 was aware of a scheme which involved plans to kill Lula and his vice-presidential running mate, Alckmin, and to imprison and murder Alexandre de Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the backing of the army and air force commanders. His successor was inaugurated without problem on January 1st, 2023.
But a seven days after, on 8 January, many Bolsonaro supporters attacked and damaged official structures in the federal district, Brazil's capital.
The law enforcement took action and around fifteen hundred individuals were detained.
The judges found that the rioters had been incited by Bolsonaro whose strategy, they said, was for the national armed forces to step in, restore order and return him to office.
At the moment, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also banned from campaigning for office until the year 2060 - eight years later after the end of his sentence.
The former president called the court case a "witch hunt and said it was intended to stop him competing in the next presidential race.
