Bolsonaro has been detained after authorities found he posed a concrete flight risk while under house arrest.
The ex-president was convicted of plotting a government overthrow in last fall and handed more than a 27-year term in jail, but he was staying under home detention pending court reviews.
High Court Judge Justice Moraes said the decision to arrest the septuagenarian politician was a safety action after recent developments were revealed.
This included attempting to break his ankle monitor and a call for a demonstration that could enable a chance to flee".
Judicial Records Show Flight Fears
In a document approving the arrest, the magistrate said intelligence from the facility tracking Bolsonaro's house arrest suggested the former leader's aim to disable the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be "facilitated by the chaos caused by the demonstration called by his child.
His son, Flávio Bolsonaro, who serves as a senator, called for a assembly of his supporters near the former president's residence to take place on Saturday evening.
His son wrote on online platforms on Friday: "Are you going to fight for your homeland, or watch it all from your phone there on your couch? I call on you to battle with us."
He said the vigil would be so followers could offer prayers for his well-being and for the restoration of democratic rule in our nation."
Foreign Shelter Risks
Part of the judge's ruling was the chance of the former president's "relocation to foreign missions near the dwelling, considering that the inquiries revealed a background of arranging to ask for protection through a diplomatic representation", a declaration said.
The court filing underscores that the American diplomatic mission in the federal district, the capital city, is located around 13km from his dwelling.
Global Responses
His judicial problems have provoked anger from fellow populist conservative American leader Trump, leading him to implement a fifty percent tax on goods coming from Brazil.
He is being detained in a federal law enforcement building in Brazil's capital city and will undergo a custody hearing on the following day.
Latest Court Petitions
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 domestic detention, with electronic monitoring.
They also asked that the former president be permitted to exit his dwelling for medical care, saying he demanded frequent medical attention for respiratory ailments and other health problems.
Background on Conviction
He was determined responsible of leading a plot aimed at keeping him in power after he failed to win the presidential race to his political opponent, Lula.
Top judicial officials said that he had knowledge of a plan which included plans to kill the current president and his VP candidate, Alckmin, and to arrest and execute the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The scheme was stopped because it failed to get the backing of the armed forces officials. The current president was inaugurated without problem on January 1st, 2023.
But a seven days after, on January 8th, thousands of his backers invaded and destroyed public facilities in the national capital, the capital city.
The security forces stepped in and around 1,500 people were taken into custody.
The justices found that the rioters had been incited by the former president whose scheme, they said, was for the Brazilian military to take action, bring back stability and bring him back to power.
At the time, his attorneys called the over 27-year sentence "absurdly excessive.
He was also prohibited from campaigning for office until twenty-sixty - a decade minus two years after the end of his sentence.
The one-time head of state called the court case a "witch hunt and said it was designed to prevent him running in the next presidential race.
