Jair Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of orchestrating a government overthrow in the ninth month and sentenced more than over two decades in prison, but he was staying under home detention pending court reviews.
Top Judicial Official Justice Moraes said the move to detain the 70-year-old politician was a safety action after fresh information were revealed.
This encompassed trying to remove his ankle monitor and a call for a public vigil that could enable a potential flight.
In a paperwork permitting the detention, Justice Moraes said intelligence from the centre monitoring the former president's confinement suggested the ex-president's aim to disable the surveillance device to guarantee victory in his getaway".
This, it said, would be assisted by the disorder caused by the protest called by his offspring.
His child, Flávio Bolsonaro, who works as a senator, called for a meeting of his followers near his father's house to take place on Saturday evening.
His son wrote on online platforms on Friday: "Are you going to fight for your country, or watch it all from your phone there on your settee? I urge you to struggle with us."
He said the gathering would be so followers could "pray for his well-being and for the reestablishment of democratic governance in our country."
Part of the judge's ruling 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 ask for protection through a embassy office", a announcement said.
The court filing emphasizes that the United States embassy in the national capital, Brasilia, is positioned around 8 miles from Bolsonaro's home.
The former president's legal troubles have generated frustration from fellow right-wing populist United States President Donald Trump, leading him to enact a 50% tariff on Brazilian product imports.
Bolsonaro is being held in a federal law enforcement building in the capital and will have a custody hearing on the next day.
It was only on Friday that the his legal team asked the Top Court to authorize him to serve his whole jail sentence under domestic detention, with tracking devices.
They also petitioned that the former president be permitted to exit his dwelling for medical care, saying he required regular treatment for lung conditions and other illnesses.
The former president was found guilty of leading a plot aimed at keeping him in power after he was defeated in the 2022 election to his ideological adversary, President Lula.
Supreme Court justices said that he was aware of a plan which included plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute Justice Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The scheme was stopped because it failed to get the endorsement of the armed forces officials. Lula was took office without issue on the first day of 2023.
But a week later, on January 8th, numerous his followers invaded and destroyed official structures in the federal district, Brasília.
The police took action and around approximately 1,500 persons were arrested.
The judges found that the rioters had been incited by him whose plan, they said, was for the country's army to intervene, reestablish control and reinstate his authority.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also banned from running for public office until the year 2060 - a decade minus two years after the conclusion of his imprisonment.
The former president called the legal proceedings a political persecution and said it was designed to prevent him running in the 2026 national vote.
