The former Brazilian leader has been detained after authorities found he posed a serious risk of fleeing while under home confinement.
The one-time leader was found guilty of planning a armed takeover in the ninth month and handed more than 27 years in prison, but he was staying under house arrest pending appeals.
Top Judicial Official the presiding justice said the action to imprison the elderly politician was a safety action after "new facts" came to light.
This included seeking to disable his ankle monitor and a call for a supporters' gathering that could facilitate a possible escape.
Court Filing Details Escape Concerns
In a paperwork permitting the custody, Justice Moraes 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 getaway".
This, it said, would be "facilitated by the confusion caused by the protest called by his child.
His son, Flávio Bolsonaro, who holds office as a legislator, called for a gathering of his supporters near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on the previous day: Do you plan to struggle for your nation, or watch it all from your phone there on your couch? I invite you to struggle with us."
He said the vigil would be so followers could offer prayers for his health and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of the judge's ruling was the chance of Bolsonaro's transfer to embassies near the home, considering that the probes revealed a background of organizing to request asylum through a embassy office", a statement said.
The legal document underscores that the American diplomatic mission in the federal district, Brasilia, is located around 8 miles from the former president's residence.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow right-wing populist US President Donald Trump, prompting him to implement a half-rate duty on imports of Brazilian goods.
Bolsonaro is being kept in a national police facility in the capital and will have a custody hearing on the following day.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the High Court to authorize him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that the former president be permitted to leave his home for medical care, saying he needed frequent medical attention for lung conditions and other illnesses.
Context of Sentencing
He was convicted of orchestrating a plot aimed at maintaining his control after he lost the presidential race to his ideological adversary, Lula.
Top judicial officials said that he was aware of a plan which involved plans to murder his opponent and his vice-presidential running mate, Alckmin, and to detain and kill Justice Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The conspiracy was prevented because it failed to get the support of the military leaders. Lula was inaugurated without problem on the first day of 2023.
But a following week, on January 8th, thousands of Bolsonaro supporters invaded and destroyed government buildings in the national capital, Brasília.
The law enforcement took action and around 1,500 people were taken into custody.
The justices found that the rioters had been provoked by the former president whose scheme, they said, was for the Brazilian military to intervene, bring back stability and return him to office.
At the moment, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also banned from campaigning for office until 2060 - eight years later after the completion of his term.
The one-time head of state called the legal proceedings a "witch hunt and said it was intended to stop him participating in the 2026 presidential election.
