Bolsonaro has been taken into custody after authorities concluded he posed a serious risk of fleeing while under domestic detention.
The one-time leader was found guilty of planning a armed takeover in last fall and given more than over two decades in prison, but he continued under home detention pending appeals.
Top Judicial Official the presiding justice said the move to detain the elderly politician was a preventative measure after fresh information came to light.
This included attempting to break his ankle monitor and a summons to a public vigil that could facilitate a potential flight.
Legal Document Reveals Flight Fears
In a filing authorising the custody, Justice Moraes said data from the centre monitoring his home detention suggested the former leader's aim to disable the surveillance device to guarantee victory in his getaway".
This, it said, would be made easier by the confusion caused by the demonstration called by his child.
His son, his son Flávio, who works as a legislator, called for a gathering of his supporters near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on last Friday: Will you battle for your nation, or observe everything from your smartphone there on your couch? I urge you to battle with us."
He said the demonstration would be so followers could "pray for his physical condition and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of the judge's decision was the potential of his transfer to foreign missions near the home, considering that the probes revealed a history of arranging to request asylum through a consular facility", a announcement said.
The legal document emphasizes that the American diplomatic mission in the capital, Brazil's capital, is located around approximately 13 kilometers from his dwelling.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist United States President Trump, prompting him to implement a 50% tariff on imports of Brazilian goods.
The former president is being held in a federal law enforcement building in the capital and will have a imprisonment assessment on the following day.
Recent Judicial Appeals
It was only on last Friday that the former president's lawyers asked the High Court to permit him to fulfill his full incarceration period under home confinement, with tracking devices.
They also requested that the former president be authorized to exit his dwelling for healthcare, saying he needed regular treatment for lung conditions and other ailments.
Background on Conviction
He was determined responsible of orchestrating a conspiracy aimed at keeping him in power after he failed to win the national vote to his ideological adversary, President Lula.
Top judicial officials said that he had knowledge of a plot which included plans to kill his opponent and his running partner, Alckmin, and to arrest and execute the presiding judge - the High Court judge who has been overseeing the former president's case.
The scheme was prevented because it failed to get the endorsement of the army and air force commanders. Lula was sworn in without incident on January 1st, 2023.
But a following week, on the eighth of January, numerous his followers attacked and damaged public facilities in the national capital, Brasília.
The law enforcement stepped in and around fifteen hundred individuals were arrested.
The magistrates found that the protesters had been provoked by the former president whose strategy, they said, was for the national armed forces to take action, bring back stability and reinstate his authority.
At the moment, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also banned from running for public office until twenty-sixty - eight years after the conclusion of his imprisonment.
The former president called the trial a political persecution and said it was intended to stop him participating in the 2026 national vote.
