Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under domestic detention.
The one-time leader was convicted of planning a armed takeover in last fall and given more than over two decades in prison, but he continued under house arrest pending legal challenges.
High Court Judge Alexandre de Moraes said the action to imprison the 70-year-old politician was a preventative measure after fresh information emerged.
This involved attempting to break his tracking device and a call for a public vigil that could enable a chance to flee".
Court Filing Details Flight Fears
In a filing authorising the custody, the magistrate said data from the unit overseeing the former president's confinement suggested the former leader's aim to disable the surveillance device to secure accomplishment in his flight.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his son.
His offspring, Flávio, who serves as a congressional representative, called for a gathering of his backers near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on last Friday: Will you battle for your nation, or see it all from your smartphone there on your sofa? 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 nation."
Foreign Shelter Risks
Part of the judge's ruling was the chance of the former president's transfer to embassies near the residence, considering that the inquiries revealed a history of planning to request asylum through a consular facility", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the federal district, Brazil's capital, is positioned around 13km from the former president's residence.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow populist conservative United States President Donald Trump, leading him to implement a half-rate duty on Brazilian product imports.
He is being kept in a federal law enforcement building in Brazil's capital city and will undergo a detention review on the following day.
Recent Judicial Appeals
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to allow him to complete his entire prison term under home confinement, with digital surveillance.
They also asked that Bolsonaro be authorized to exit his dwelling for healthcare, saying he demanded frequent medical attention for lung conditions and other health problems.
Background on Conviction
The former president was found guilty of heading a conspiracy aimed at retaining his authority after he was defeated in the national vote to his ideological adversary, President Lula.
High Court judges said that he was aware of a plot which included plans to assassinate Lula and his running partner, his vice-presidential candidate, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been managing the former president's case.
The conspiracy was thwarted because it couldn't obtain the backing of the armed forces officials. The current president was inaugurated without problem on January 1st, 2023.
But a following week, on the eighth of January, numerous his backers stormed and vandalised official structures in the national capital, Brasília.
The law enforcement stepped in and around fifteen hundred individuals were taken into custody.
The magistrates found that the rioters had been encouraged by him whose plan, they said, was for the Brazilian military to take action, bring back stability and return him to office.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also barred from campaigning for office until twenty-sixty - a decade minus two years after the completion of his term.
The one-time head of state called the court case a "witch hunt and said it was intended to stop him running in the next presidential race.
