Jair Bolsonaro has been detained after authorities determined he posed a serious risk of fleeing while under house arrest.
The ex-president was sentenced of planning a military coup in last fall and handed more than 27 years in prison, but he continued under home detention pending legal challenges.
Top Judicial Official Justice Moraes said the decision to arrest the 70-year-old politician was a safety action after "new facts" emerged.
This involved trying to remove his electronic bracelet and a call for a public vigil that could enable a possible escape.
Judicial Records Show Escape Risks
In a filing authorising the arrest, the judge said intelligence from the unit overseeing his home detention suggested the one-time head of state's plan to remove the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the confusion caused by the gathering called by his offspring.
His offspring, his son Flávio, who works as a senator, called for a meeting of his followers near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your homeland, or see it all from your mobile device there on your couch? I urge you to struggle with us."
He said the gathering would be so followers could "pray for his health and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of Justice Moraes's determination was the potential of his move to embassies near the home, considering that the inquiries revealed a background of organizing to seek refuge through a embassy office", a declaration said.
The judicial paperwork emphasizes that the American diplomatic mission in the national capital, the capital city, is positioned around 13km from the former president's residence.
Worldwide Consequences
His judicial problems have generated frustration from fellow conservative nationalist US President President Trump, prompting him to impose a fifty percent tax on goods coming from Brazil.
Bolsonaro is being kept in a Federal Police station in Brasilia and will experience a imprisonment assessment on the following day.
Recent Legal Requests
It was only on the previous day that the former president's lawyers asked the Supreme Court to permit him to fulfill his full incarceration period under home confinement, with tracking devices.
They also petitioned that the former president be allowed to leave his home for medical treatment, saying he required frequent medical attention for pulmonary infections and other health problems.
Details of Guilty Verdict
The former president was found guilty of orchestrating a plot aimed at retaining his authority after he lost the presidential race to his political opponent, President Lula.
High Court judges said that he had knowledge of a plan which involved plans to kill his opponent and his running partner, Geraldo Alckmin, and to detain and kill Alexandre de Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the backing of the armed forces officials. His successor was sworn in without problem on the first day of 2023.
But a seven days after, on the eighth of January, thousands of Bolsonaro supporters invaded and destroyed government buildings in the federal district, Brazil's capital.
The law enforcement intervened and around approximately 1,500 persons were arrested.
The magistrates found that the rioters had been encouraged by him whose scheme, they said, was for the national armed forces to take action, bring back stability and bring him back to power.
At the period, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also barred from campaigning for office until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the court case a "witch hunt and said it was aimed at blocking him competing in the next presidential race.
