Jair Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of plotting a government overthrow in last fall and sentenced more than a 27-year term in prison, but he remained under house arrest pending court reviews.
High Court Judge Alexandre de Moraes said the decision to arrest the elderly politician was a preventative measure after "new facts" were revealed.
This involved attempting to break his electronic bracelet and a call for a public vigil that could enable a possible escape.
In a paperwork permitting the arrest, the judge said information from the centre monitoring the former president's confinement suggested the one-time head of state's plan to remove the surveillance device to secure accomplishment in his escape.
This, it said, would be assisted by the disorder caused by the protest called by his child.
His offspring, Flávio, who holds office as a legislator, called for a gathering of his followers near Bolsonaro's home to take place on Saturday night.
His son wrote on social media on the previous day: "Are you going to fight for your country, or observe everything from your mobile device there on your sofa? I call on you to struggle with us."
He said the vigil would be so backers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our country."
Part of the judge's ruling was the chance of Bolsonaro's transfer to foreign missions near the residence, considering that the probes revealed a background of arranging to request asylum through a consular facility", a announcement said.
The court filing highlights that the US embassy in the capital, the capital city, is situated around 8 miles from Bolsonaro's home.
Bolsonaro's legal woes have generated frustration from fellow conservative nationalist United States President Trump, leading him to implement a fifty percent tax on Brazilian product imports.
He is being detained in a federal law enforcement building in the capital and will have a detention review on the following day.
It was only on Friday that the former president's lawyers asked the Supreme Court to allow him to complete his entire prison term under home confinement, with digital surveillance.
They also requested that he be authorized to depart his residence for healthcare, saying he needed frequent medical attention for respiratory ailments and other illnesses.
Bolsonaro was determined responsible of orchestrating a plot aimed at keeping him in power after he failed to win the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a scheme which included plans to kill Lula and his running partner, Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been presiding over his judicial proceedings.
The plot was stopped because it didn't receive the backing of the armed forces officials. The current president was took office without incident on 1 January 2023.
But a seven days after, on January 8th, numerous his followers attacked and damaged public facilities in the national capital, Brazil's capital.
The security forces stepped in and around 1,500 people were arrested.
The magistrates found that the protesters had been encouraged by Bolsonaro whose plan, they said, was for the national armed forces to step in, reestablish control and return him to office.
At the moment, the legal team called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - a decade minus two years after the completion of his term.
The former president called the trial a targeted investigation" and said it was aimed at blocking him participating in the next presidential race.
