Bolsonaro has been detained after authorities determined he posed a serious risk of fleeing while under home confinement.
The former head of state was found guilty of planning a armed takeover in September and sentenced more than over two decades in jail, but he remained under house arrest pending legal challenges.
High Court Judge the presiding justice said the action to imprison the 70-year-old politician was a safety action after recent developments came to light.
This encompassed seeking to disable his ankle monitor and a summons to a supporters' gathering that could facilitate a potential flight.
Judicial Records Show Escape Risks
In a document approving the arrest, Justice Moraes said intelligence from the centre monitoring his home detention suggested the one-time head of state's plan to remove the tracking monitor to guarantee victory in his flight.
This, it said, would be assisted by the chaos caused by the demonstration called by his child.
His offspring, his son Flávio, who works as a congressional representative, called for a assembly of his followers near the former president's residence to take place on the weekend.
His son wrote on digital networks on last Friday: Will you battle for your nation, or observe everything from your smartphone there on your couch? I call on you to struggle with us."
He said the gathering 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 the judge's decision was the potential of the former president's move to embassies near the home, considering that the investigations revealed a background of organizing to request asylum through a consular facility", a announcement said.
The legal document emphasizes that the American diplomatic mission in the federal district, Brasilia, is located around 13km from his dwelling.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow right-wing populist US President Trump, prompting him to impose a 50% tariff on Brazilian product imports.
Bolsonaro is being held in a Federal Police station in Brasilia and will experience a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on last Friday that the his legal team asked the High Court to allow him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also requested that the former president be authorized to depart his residence for medical treatment, saying he demanded regular treatment for pulmonary infections and other health problems.
Details of Guilty Verdict
He was determined responsible of leading a conspiracy aimed at maintaining his control after he lost the national vote to his left-wing rival, Lula.
Supreme Court justices said that he was aware of a plot which involved plans to assassinate the current president and his running partner, Alckmin, and to arrest and execute Justice Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The plot was thwarted because it didn't receive the backing of the armed forces officials. The current president was sworn in without incident on 1 January 2023.
But a seven days after, on the eighth of January, thousands of his followers stormed and vandalised public facilities in the federal district, Brasília.
The police intervened and around fifteen hundred individuals were detained.
The judges found that the demonstrators had been incited by the former president whose scheme, they said, was for the country's army to intervene, restore order and return him to office.
At the period, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also banned from running for public office until 2060 - a decade minus two years after the completion of his term.
The former president called the trial a political persecution and said it was aimed at blocking him participating in the 2026 presidential election.
