The former Brazilian leader has been detained after authorities determined he posed a definite escape threat while under domestic detention.
The former head of state was sentenced of orchestrating a government overthrow in September and handed more than a 27-year term in jail, but he was staying under house arrest pending appeals.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the elderly politician was a safety action after fresh information came to light.
This encompassed trying to remove his ankle monitor and a call for a public vigil that could facilitate a possible escape.
Legal Document Reveals Flight Fears
In a filing authorising the detention, the magistrate said information from the unit overseeing the former president's confinement suggested the one-time head of state's "intention to break the tracking monitor to guarantee victory in his escape.
This, it said, would be assisted by the chaos caused by the gathering called by his child.
His offspring, Flávio Bolsonaro, who serves as a congressional representative, called for a meeting of his followers near his father's house to take place on Saturday night.
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 settee? I call on you to fight with us."
He said the vigil would be so supporters could offer prayers for his well-being and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the chance of the former president's move to diplomatic missions near the home, considering that the probes revealed a history of organizing to request asylum through a consular facility", a announcement said.
The legal document highlights that the American diplomatic mission in the capital, Brazil's capital, is positioned around 13km from his dwelling.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow populist conservative American leader President Trump, causing him to implement a fifty percent tax on Brazilian product imports.
The former president is being held in a federal law enforcement building in Brasilia and will experience a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on Friday that the former president's lawyers asked the High Court to allow him to fulfill his full incarceration period under home confinement, with electronic monitoring.
They also petitioned that he be authorized to depart his residence for healthcare, saying he demanded regular treatment for pulmonary infections and other illnesses.
Context of Sentencing
Bolsonaro was convicted of orchestrating a conspiracy aimed at retaining his authority after he lost the national vote to his left-wing rival, Lula.
High Court judges said that he was aware of a plan which involved plans to murder Lula and his VP candidate, his vice-presidential candidate, and to imprison and murder Alexandre de Moraes - the top judicial official who has been managing the former president's case.
The conspiracy was stopped because it didn't receive the backing of the army and air force commanders. Lula was took office without incident on 1 January 2023.
But a seven days after, on 8 January, many his followers stormed and vandalised public facilities in the national capital, Brazil's capital.
The police took action and around 1,500 people were taken into custody.
The judges found that the demonstrators had been incited by him whose scheme, they said, was for the country's army to take action, reestablish control and reinstate his authority.
At the time, the legal team called the decades-long sentence "absurdly excessive.
He was also banned from campaigning for office until twenty-sixty - eight years later after the conclusion of his imprisonment.
The one-time head of state called the court case a "witch hunt and said it was designed to prevent him participating in the 2026 national vote.
