Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under domestic detention.
The one-time leader was sentenced of plotting a military coup in the ninth month and sentenced more than over two decades in incarceration, but he was staying under confinement pending legal challenges.
High Court Judge the presiding justice said the action to imprison the 70-year-old politician was a precautionary step after recent developments came to light.
This included seeking to disable his ankle monitor and a summons to a supporters' gathering that could enable a chance to flee".
Court Filing Details Flight Fears
In a paperwork permitting the detention, the judge said data from the centre monitoring Bolsonaro's house arrest suggested the former leader's aim to disable the tracking monitor to secure accomplishment in his flight.
This, it said, would be assisted by the chaos caused by the gathering called by his son.
His child, Flávio Bolsonaro, who works as a senator, called for a assembly of his supporters near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on social media on last Friday: Will you battle for your country, or watch it all from your smartphone there on your settee? I invite you to battle with us."
He said the vigil would be so supporters could offer prayers for his health and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of the magistrate's ruling was the chance of his move to embassies near the residence, considering that the inquiries revealed a history of arranging to request asylum through a embassy office", a announcement said.
The court filing underscores that the American diplomatic mission in the national capital, Brasilia, is located around approximately 13 kilometers from his dwelling.
Global Responses
Bolsonaro's legal woes have provoked anger from fellow right-wing populist United States President Donald Trump, prompting him to enact a half-rate duty on Brazilian product imports.
He is being held in a federal law enforcement building in Brazil's capital city and will have a custody hearing on Sunday.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the Top Court to allow him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that the former president be allowed to leave his home for medical treatment, saying he needed regular treatment for respiratory ailments and other health problems.
Details of Guilty Verdict
The former president was convicted of orchestrating a conspiracy aimed at maintaining his control after he failed to win the national vote to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which involved plans to kill Lula and his VP candidate, Alckmin, and to detain and kill Justice Moraes - the top judicial official who has been managing the former president's case.
The conspiracy was stopped because it failed to get the backing of the military leaders. The current president was took office without problem on 1 January 2023.
But a following week, on 8 January, many Bolsonaro supporters stormed and vandalised official structures in the capital, Brazil's capital.
The security forces intervened and around 1,500 people were detained.
The magistrates found that the rioters had been incited by Bolsonaro whose plan, they said, was for the country's army to intervene, restore order and bring him back to power.
At the period, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also banned from running for public office until twenty-sixty - a decade minus two years after the end of his sentence.
The one-time head of state called the court case a targeted investigation" and said it was intended to stop him competing in the next presidential race.
