The former Brazilian leader has been taken into custody after authorities determined he posed a definite escape threat while under domestic detention.
The ex-president was found guilty of orchestrating a armed takeover in the ninth month and handed more than 27 years in incarceration, but he was staying under house arrest pending court reviews.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a preventative measure after fresh information emerged.
This encompassed attempting to break his tracking device and a call for a supporters' gathering that could enable a possible escape.
Court Filing Details Flight Fears
In a filing authorising the arrest, the judge said information from the facility tracking his home detention suggested the one-time head of state's plan to remove the tracking monitor to ensure success in his flight.
This, it said, would be "facilitated by the confusion caused by the gathering called by his child.
His child, Flávio, who holds office as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
The senator wrote on digital networks on last Friday: Will you battle for your country, or watch it all from your smartphone there on your sofa? I call on you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his physical condition and for the return of democracy in our land."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the chance of Bolsonaro's "relocation to diplomatic missions near the home, considering that the probes revealed a background of organizing to ask for protection through a embassy office", a declaration said.
The court filing underscores that the US embassy in the national capital, Brazil's capital, is situated around 8 miles from his dwelling.
Global Responses
His judicial problems have drawn the ire of fellow right-wing populist US President Trump, prompting him to enact a 50% tariff on Brazilian product imports.
He is being detained in a Federal Police station in the capital and will undergo a detention review on the following day.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that Bolsonaro be authorized to depart his residence for medical treatment, saying he demanded ongoing care for pulmonary infections and other ailments.
Context of Sentencing
He was convicted of orchestrating a conspiracy aimed at maintaining his control after he failed to win the presidential race to his ideological adversary, President Lula.
Top judicial officials said that he had knowledge of a plan which included plans to assassinate his opponent and his running partner, Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been overseeing Bolsonaro's trial.
The scheme was thwarted because it failed to get the backing of the military leaders. Lula was inaugurated without problem on January 1st, 2023.
But a week later, on 8 January, numerous his followers attacked and damaged government buildings in the capital, Brasília.
The law enforcement took action and around 1,500 people were arrested.
The justices found that the protesters had been incited by the former president whose scheme, they said, was for the national armed forces to take action, reestablish control and return him to office.
At the period, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also barred from campaigning for office until 2060 - eight years later after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a targeted investigation" and said it was designed to prevent him running in the next presidential race.
