Jair Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under home confinement.
The one-time leader was found guilty of plotting a government overthrow in September and given more than over two decades in jail, but he continued under home detention pending court reviews.
Brazilian Supreme Court Justice Justice Moraes said the decision to arrest the elderly politician was a safety action after fresh information were revealed.
This encompassed trying to remove his ankle monitor and a summons to a supporters' gathering that could facilitate a possible escape.
Judicial Records Show Flight Fears
In a paperwork permitting the custody, the magistrate said data from the centre monitoring the former president's confinement suggested the ex-president's aim to disable the electronic ankle bracelet to guarantee victory in his flight.
This, it said, would be made easier by the chaos caused by the gathering called by his offspring.
His son, his son Flávio, who serves as a congressional representative, called for a gathering of his backers near his father's house to take place on Saturday night.
His son wrote on online platforms on last Friday: "Are you going to fight for your country, or observe everything from your smartphone there on your sofa? I invite you to battle with us."
He said the gathering would be so backers could "pray for his physical condition and for the return of democracy in our country."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the possibility of the former president's "relocation to embassies near the home, considering that the probes revealed a history of planning to ask for protection through a consular facility", a announcement said.
The judicial paperwork emphasizes that the American diplomatic mission in the national capital, the capital city, is situated around approximately 13 kilometers from his dwelling.
Global Responses
His judicial problems have drawn the ire of fellow conservative nationalist US President Donald Trump, leading him to impose a fifty percent tax on imports of Brazilian goods.
The former president is being kept in a Federal Police station in Brazil's capital city and will undergo a custody hearing on the following day.
Recent Legal Requests
It was only on the previous day that the his legal team asked the High Court to allow him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also asked that the former president be authorized to exit his dwelling for medical treatment, saying he demanded ongoing care for respiratory ailments and other ailments.
Context of Sentencing
The former president was determined responsible of orchestrating a conspiracy aimed at keeping him in power after he lost the presidential race to his ideological adversary, President Lula.
High Court judges said that he knew of a plot which encompassed plans to murder Lula and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the top judicial official who has been overseeing his judicial proceedings.
The scheme was stopped because it failed to get the support of the military leaders. His successor was took office without incident on the first day of 2023.
But a following week, on 8 January, thousands of Bolsonaro supporters invaded and destroyed government buildings in the national capital, the capital city.
The security forces intervened and around approximately 1,500 persons were detained.
The magistrates found that the demonstrators had been incited by the former president whose plan, they said, was for the Brazilian military to intervene, bring back stability and bring him back to power.
At the moment, the legal team called the decades-long sentence extremely harsh.
He was also prohibited from campaigning for office until twenty-sixty - eight years after the end of his sentence.
The ex-leader called the court case a political persecution and said it was intended to stop him competing in the 2026 national vote.
