Bolsonaro has been arrested after authorities concluded he posed a serious risk of fleeing while under domestic detention.
The ex-president was sentenced of orchestrating a military coup in the ninth month and sentenced more than 27 years in incarceration, but he remained under confinement pending court reviews.
High Court Judge Alexandre de Moraes said the move to detain the septuagenarian politician was a safety action after "new facts" were revealed.
This involved seeking to disable his tracking device and a call for a public vigil that could facilitate a potential flight.
Court Filing Details Flight Fears
In a paperwork permitting the custody, Justice Moraes said information from the centre monitoring his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be made easier by the disorder caused by the demonstration called by his son.
His child, his son Flávio, who works as a congressional representative, called for a assembly of his followers near Bolsonaro's home to take place on Saturday evening.
His son wrote on online platforms on last Friday: Will you battle for your homeland, or see it all from your smartphone there on your settee? I invite you to fight with us."
He said the gathering would be so followers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of the magistrate's decision was the potential of the former president's move to embassies near the dwelling, considering that the inquiries revealed a background of planning to request asylum through a consular facility", a statement said.
The judicial paperwork emphasizes that the American diplomatic mission in the national capital, Brazil's capital, is situated around 8 miles from his dwelling.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow populist conservative United States President Trump, prompting him to enact a half-rate duty on imports of Brazilian goods.
He is being held in a federal law enforcement building in Brazil's capital city and will experience a detention review on the next day.
Recent Legal Requests
It was only on Friday that the former president's lawyers asked the High Court to authorize him to complete his entire prison term under house arrest, with electronic monitoring.
They also requested that he be allowed to depart his residence for healthcare, saying he demanded regular treatment for pulmonary infections and other illnesses.
Context of Sentencing
He was determined responsible of leading a conspiracy aimed at keeping him in power after he was defeated in the national vote to his left-wing rival, Lula.
Top judicial officials said that he knew of a plan which included plans to murder Lula and his vice-presidential running mate, his vice-presidential candidate, and to detain and kill the presiding judge - the Supreme Court justice who has been presiding over the former president's case.
The scheme was thwarted because it didn't receive the support of the armed forces officials. Lula was sworn in without problem on the first day of 2023.
But a seven days after, on January 8th, many Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brasília.
The security forces took action and around fifteen hundred individuals were taken into custody.
The magistrates found that the protesters had been provoked by the former president whose scheme, they said, was for the national armed forces to step in, reestablish control and return him to office.
At the period, the legal team called the over 27-year sentence unreasonably severe".
He was also prohibited from running for public office until twenty-sixty - eight years after the completion of his term.
The one-time head of state called the court case a political persecution and said it was aimed at blocking him running in the next presidential race.
