Bolsonaro has been taken into custody after authorities concluded he posed a definite escape threat while under domestic detention.
The one-time leader was convicted of orchestrating a armed takeover in September and given more than over two decades in prison, but he continued under home detention pending appeals.
High Court Judge Justice Moraes said the move to detain the elderly politician was a precautionary step after fresh information came to light.
This involved trying to remove his ankle monitor and a summons to a supporters' gathering that could facilitate a potential flight.
Judicial Records Show Flight Fears
In a paperwork permitting the custody, Justice Moraes said data from the facility tracking his home detention suggested the former leader's aim to disable the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be assisted by the chaos caused by the demonstration called by his child.
His offspring, Flávio Bolsonaro, who works as a congressional representative, called for a gathering of his backers near his father's house to take place on the weekend.
The senator wrote on digital networks on last Friday: Will you battle for your nation, or observe everything from your mobile device there on your settee? I invite you to battle with us."
He said the demonstration would be so followers could "pray for his well-being and for the reestablishment of democratic governance in our country."
Foreign Shelter Risks
Part of the judge's determination was the possibility of the former president's move to diplomatic missions near the home, considering that the inquiries revealed a background of arranging to request asylum through a diplomatic representation", a declaration said.
The judicial paperwork underscores that the American diplomatic mission in the capital, Brasilia, is positioned around 8 miles from the former president's residence.
International Reactions
The former president's legal troubles have drawn the ire of fellow populist conservative US President Trump, leading him to impose a fifty percent tax on imports of Brazilian goods.
He is being detained in a national police facility in Brasilia and will undergo a imprisonment assessment on the following day.
Latest Court Petitions
It was only on the previous day that the his legal team asked the Supreme Court to authorize him to serve his whole jail sentence under domestic detention, with digital surveillance.
They also requested that the former president be allowed to leave his home for medical care, saying he required frequent medical attention for lung conditions and other illnesses.
Details of Guilty Verdict
He was found guilty of heading a conspiracy aimed at keeping him in power after he failed to win the 2022 election to his political opponent, Lula.
Supreme Court justices said that he was aware of a plot which involved plans to murder Lula and his VP candidate, Alckmin, and to detain and kill Alexandre de Moraes - the top judicial official who has been presiding over the former president's case.
The scheme was prevented because it failed to get the endorsement of the army and air force commanders. The current president was took office without incident on 1 January 2023.
But a following week, on the eighth of January, numerous Bolsonaro supporters invaded and destroyed official structures in the capital, Brasília.
The security forces stepped in and around approximately 1,500 persons were detained.
The judges found that the protesters had been incited by Bolsonaro whose strategy, they said, was for the country's army to step in, reestablish control and bring him back to power.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence extremely harsh.
He was also prohibited from campaigning for office until twenty-sixty - eight years after the completion of his term.
The ex-leader called the legal proceedings a political persecution and said it was aimed at blocking him competing in the next presidential race.
