Bolsonaro has been arrested after authorities concluded he posed a serious risk of fleeing while under home confinement.
The ex-president was convicted of planning a military coup in the ninth month and given more than over two decades in incarceration, but he continued under confinement pending court reviews.
High Court Judge the presiding justice said the decision to arrest the 70-year-old politician was a safety action after recent developments were revealed.
This included attempting to break his tracking device and a summons to a public vigil that could "allow for a potential flight.
Legal Document Reveals Flight Fears
In a document approving the custody, Justice Moraes said information from the unit overseeing Bolsonaro's house arrest suggested the ex-president's aim to disable the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be "facilitated by the disorder caused by the protest called by his offspring.
His offspring, Flávio Bolsonaro, who serves as a legislator, called for a assembly of his backers near the former president's residence to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on Friday: "Are you going to fight for your homeland, or watch it all from your mobile device there on your couch? I invite you to fight with us."
He said the gathering would be so supporters could offer prayers for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's determination was the potential of the former president's move to foreign missions near the dwelling, considering that the inquiries revealed a history of planning to request asylum through a embassy office", a statement said.
The legal document underscores that the American diplomatic mission in the federal district, Brazil's capital, is positioned around 13km from the former president's residence.
Worldwide Consequences
His judicial problems have provoked anger from fellow populist conservative United States President President Trump, leading him to enact a half-rate duty on goods coming from Brazil.
He is being detained in a national police facility in Brasilia and will have a detention review on Sunday.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the High Court to allow him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also petitioned that the former president be allowed to exit his dwelling for medical treatment, saying he needed regular treatment for respiratory ailments and other health problems.
Context of Sentencing
The former president was determined responsible of leading a scheme aimed at retaining his authority after he was defeated in the presidential race to his ideological adversary, Lula.
Supreme Court justices said that he knew of a plan which involved plans to murder the current president and his vice-presidential running mate, Alckmin, and to arrest and execute the presiding judge - the Supreme Court justice who has been overseeing his judicial proceedings.
The conspiracy was stopped because it didn't receive the support of the armed forces officials. The current president was took office without incident on January 1st, 2023.
But a week later, on 8 January, thousands of his followers invaded and destroyed public facilities in the capital, Brazil's capital.
The security forces intervened and around fifteen hundred individuals were arrested.
The judges found that the protesters had been incited by Bolsonaro whose strategy, they said, was for the national armed forces to intervene, bring back stability and reinstate his authority.
At the moment, his attorneys called the 27 years and three months sentence extremely harsh.
He was also banned from running for public office until twenty-sixty - eight years later after the end of his sentence.
The former president called the court case a political persecution and said it was intended to stop him running in the next presidential race.
