Jair Bolsonaro has been arrested after authorities concluded he posed a concrete flight risk while under domestic detention.
The one-time leader was found guilty of planning a armed takeover in September and handed more than over two decades in incarceration, but he remained under confinement pending court reviews.
Top Judicial Official the presiding justice said the decision to arrest the elderly politician was a precautionary step after fresh information came to light.
This involved seeking to disable his electronic bracelet and a invitation to a supporters' gathering that could enable a chance to flee".
In a filing authorising the arrest, the judge said intelligence from the facility tracking his home detention suggested the one-time head of state's plan to remove the tracking monitor to ensure success in his getaway".
This, it said, would be assisted by the chaos caused by the demonstration called by his son.
His offspring, Flávio, who holds office as a senator, called for a assembly of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on Friday: Will you battle for your country, or watch it all from your smartphone there on your couch? I invite you to battle with us."
He said the gathering would be so backers could offer prayers for his well-being and for the return of democracy in our country."
Part of Justice Moraes's determination was the possibility of his "relocation to diplomatic missions near the residence, considering that the inquiries revealed a background of planning to request asylum through a diplomatic representation", a statement said.
The legal document emphasizes that the United States embassy in the national capital, Brazil's capital, is positioned around 8 miles from the former president's residence.
His judicial problems have provoked anger from fellow conservative nationalist United States President Trump, prompting him to enact a half-rate duty on Brazilian product imports.
He is being kept in a Federal Police station in the capital and will have a imprisonment assessment on the following day.
It was only on the previous day that the his legal team asked the Supreme Court to permit him to complete his entire prison term under house arrest, with tracking devices.
They also petitioned that the former president be permitted to depart his residence for medical treatment, saying he demanded regular treatment for pulmonary infections and other illnesses.
Bolsonaro was determined responsible of leading a conspiracy aimed at maintaining his control after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Top judicial officials said that he was aware of a plan which involved plans to kill the current president and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder the presiding judge - the High Court judge who has been overseeing Bolsonaro's trial.
The plot was stopped because it couldn't obtain the endorsement of the army and air force commanders. Lula was sworn in without incident on 1 January 2023.
But a week later, on the eighth of January, thousands of his followers stormed and vandalised government buildings in the federal district, the capital city.
The law enforcement stepped in and around approximately 1,500 persons were arrested.
The judges found that the demonstrators had been incited by him whose plan, they said, was for the country's army to intervene, bring back stability and return him to office.
At the period, his attorneys called the over 27-year sentence "absurdly excessive.
He was also prohibited from campaigning for office until the year 2060 - eight years later after the completion of his term.
The former president called the trial a targeted investigation" and said it was designed to prevent him competing in the next presidential race.
