The ex-president was found guilty of orchestrating a armed takeover in September and handed more than 27 years in prison, but he continued under confinement pending court reviews.
Top Judicial Official the presiding justice said the action to imprison the septuagenarian politician was a precautionary step after fresh information were revealed.
This encompassed seeking to disable his tracking device and a invitation to a supporters' gathering that could "allow for a potential flight.
Court Filing Details Escape Risks
In a filing authorising the arrest, Justice Moraes said data from the facility tracking Bolsonaro's house arrest suggested the ex-president's "intention to break the surveillance device to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the gathering called by his child.
His offspring, Flávio, who serves as a congressional representative, called for a assembly of his followers near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on Friday: "Are you going to fight for your homeland, or watch it all from your mobile device there on your settee? I call on you to struggle with us."
He said the demonstration would be so backers could offer prayers for his well-being and for the restoration of democratic rule in our country."
Embassy Asylum Concerns
Part of Justice Moraes's determination was the possibility of his move to diplomatic missions near the residence, considering that the investigations revealed a background of planning to ask for protection through a diplomatic representation", a announcement said.
The legal document underscores that the US embassy in the national capital, Brasilia, is situated around 8 miles from the former president's residence.
International Reactions

Bolsonaro is being held in a federal law enforcement building in the capital and will have a detention review on the next day.
Recent Legal Requests

Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a plot aimed at retaining his authority after he failed to win the national vote to his ideological adversary, Lula.
High Court judges said that he was aware of a plot which included plans to assassinate the current president and his VP candidate, Alckmin, and to arrest and execute Alexandre de Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The plot was thwarted because it couldn't obtain the backing of the military leaders. Lula was took office without incident on the first day of 2023.
But a following week, on the eighth of January, thousands of his backers stormed and vandalised public facilities in the capital, the capital city.
The law enforcement stepped in and around 1,500 people were arrested.
The justices found that the rioters had been encouraged by him whose scheme, they said, was for the country's army to step in, bring back stability and bring him back to power.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence unreasonably severe".
He was also banned from seeking elected position until the year 2060 - eight years after the end of his sentence.
The former president called the court case a targeted investigation" and said it was designed to prevent him participating in the 2026 presidential election.
