Jair Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under domestic detention.
The ex-president was convicted of plotting a armed takeover in September and given more than a 27-year term in incarceration, but he continued under house arrest pending legal challenges.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the 70-year-old politician was a safety action after recent developments came to light.
This involved seeking to disable his tracking device and a invitation to a demonstration that could enable a possible escape.
Judicial Records Show Escape Risks
In a filing authorising the arrest, Justice Moraes said intelligence from the centre monitoring his home detention suggested the former leader's aim to disable the surveillance device to guarantee victory in his flight.
This, it said, would be assisted by the confusion caused by the protest called by his child.
His offspring, Flávio, who serves as a congressional representative, called for a meeting of his backers near his father's house to take place on the weekend.
Flávio Bolsonaro wrote on online platforms on last Friday: Do you plan to struggle for your country, or watch it all from your phone there on your couch? I call on you to fight with us."
He said the vigil would be so backers could "pray for his well-being and for the restoration of democratic rule in our country."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the potential of the former president's move to foreign missions near the home, considering that the investigations revealed a background of planning to ask for protection through a consular facility", a announcement said.
The legal document highlights that the United States embassy in the national capital, Brasilia, is situated around 8 miles from the former president's residence.
Global Responses
The former president's legal troubles have generated frustration from fellow populist conservative American leader Donald Trump, causing him to enact a fifty percent tax on goods coming from Brazil.
He is being held in a national police facility in Brasilia and will have a detention review on the following day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the High Court to permit him to complete his entire prison term under house arrest, with tracking devices.
They also requested that he be permitted to depart his residence for medical treatment, saying he required ongoing care for respiratory ailments and other illnesses.
Details of Guilty Verdict
He was found guilty of leading a scheme aimed at keeping him in power after he failed to win the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he had knowledge of a scheme which encompassed plans to kill Lula and his VP candidate, Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The conspiracy was stopped because it failed to get the backing of the military leaders. The current president was took office without problem on the first day of 2023.
But a following week, on January 8th, numerous his followers stormed and vandalised public facilities in the capital, Brasília.
The law enforcement took action and around approximately 1,500 persons were taken into custody.
The judges found that the demonstrators had been encouraged by him whose strategy, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the time, Bolsonaro's lawyers called the decades-long sentence extremely harsh.
He was also barred from seeking elected position until the year 2060 - eight years after the conclusion of his imprisonment.
The former president called the legal proceedings a political persecution and said it was aimed at blocking him participating in the next presidential race.
