Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under home confinement.
The ex-president was sentenced of plotting a military coup in September and handed more than a 27-year term in incarceration, but he continued under home detention pending legal challenges.
High Court Judge Justice Moraes said the action to imprison the 70-year-old politician was a preventative measure after fresh information emerged.
This included attempting to break his tracking device and a summons to a public vigil that could "allow for a potential flight.
Legal Document Reveals Escape Concerns
In a paperwork permitting the detention, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the former leader's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the chaos caused by the gathering called by his child.
His child, his son Flávio, who serves as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday evening.
The senator wrote on digital networks on the previous day: Will you battle for your homeland, or see it all from your phone there on your settee? I call on you to battle with us."
He said the demonstration would be so supporters could "pray for his physical condition and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of Justice Moraes's determination was the potential of the former president's move to embassies near the dwelling, considering that the investigations revealed a history of arranging to request asylum through a consular facility", a declaration said.
The court filing underscores that the United States embassy in the national capital, Brasilia, is located around approximately 13 kilometers from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have drawn the ire of fellow populist conservative American leader Donald Trump, leading him to impose a fifty percent tax on goods coming from Brazil.
The former president is being held in a national police facility in Brasilia and will undergo a imprisonment assessment on Sunday.
Latest Court Petitions
It was only on last Friday that the his legal team asked the Supreme Court to authorize him to serve his whole jail sentence under home confinement, with tracking devices.
They also petitioned that Bolsonaro be allowed to exit his dwelling for medical care, saying he needed ongoing care for respiratory ailments and other illnesses.
Background on Conviction
Bolsonaro was found guilty of leading a conspiracy aimed at maintaining his control after he failed to win the 2022 election to his ideological adversary, Lula.
Supreme Court justices said that he had knowledge of a plan which encompassed plans to assassinate Lula and his running partner, his vice-presidential candidate, and to imprison and murder Justice Moraes - the top judicial official who has been managing the former president's case.
The conspiracy was thwarted because it couldn't obtain the support of the armed forces officials. Lula was sworn in without incident on January 1st, 2023.
But a seven days after, on the eighth of January, many his followers attacked and damaged government buildings in the national capital, Brazil's capital.
The law enforcement stepped in and around fifteen hundred individuals were detained.
The judges found that the demonstrators had been encouraged by the former president whose scheme, they said, was for the national armed forces to take action, bring back stability and bring him back to power.
At the moment, his attorneys called the decades-long sentence unreasonably severe".
He was also barred from running for public office until twenty-sixty - a decade minus two years after the conclusion of his imprisonment.
The ex-leader called the trial a "witch hunt and said it was designed to prevent him competing in the next presidential race.
