Bolsonaro has been detained after authorities found he posed a concrete flight risk while under domestic detention.
The one-time leader was found guilty of planning a military coup in last fall and given more than 27 years in jail, but he was staying under house arrest pending appeals.
High Court Judge Alexandre de Moraes said the move to detain the 70-year-old politician was a safety action after recent developments were revealed.
This involved attempting to break his electronic bracelet and a invitation to a public vigil that could "allow for a chance to flee".
Legal Document Reveals Escape Risks
In a document approving the arrest, the judge said data from the centre monitoring his home detention suggested the one-time head of state's plan to remove the tracking monitor to secure accomplishment in his getaway".
This, it said, would be assisted by the confusion caused by the gathering called by his son.
His child, Flávio Bolsonaro, who works as a senator, called for a gathering of his supporters near the former president's residence to take place on Saturday night.
His son wrote on social media on the previous day: Do you plan to struggle for your nation, or see it all from your smartphone there on your sofa? I call on you to battle with us."
He said the gathering would be so supporters could offer prayers for his physical condition and for the reestablishment of democratic governance in our land."
Diplomatic Refuge Fears
Part of the magistrate's decision was the chance of his transfer to embassies near the dwelling, considering that the investigations revealed a background of arranging to request asylum through a consular facility", a statement said.
The judicial paperwork highlights that the American diplomatic mission in the capital, the capital city, is located around approximately 13 kilometers from Bolsonaro's home.
International Reactions
His judicial problems have generated frustration from fellow populist conservative United States President President Trump, leading him to impose a half-rate duty on Brazilian product imports.
Bolsonaro is being held in a national police facility in Brasilia and will undergo a custody hearing on Sunday.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under house arrest, with tracking devices.
They also asked that the former president be authorized to exit his dwelling for medical care, saying he required frequent medical attention for lung conditions and other illnesses.
Details of Guilty Verdict
The former president was convicted of heading a plot aimed at keeping him in power after he failed to win the presidential race to his ideological adversary, Lula.
High Court judges said that he had knowledge of a plot which involved plans to assassinate the current president and his VP candidate, Geraldo Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The scheme was prevented because it didn't receive the endorsement of the army and air force commanders. Lula was took office without incident on January 1st, 2023.
But a seven days after, on 8 January, thousands of his backers invaded and destroyed official structures in the capital, the capital city.
The law enforcement took action and around approximately 1,500 persons were detained.
The judges found that the protesters had been provoked by Bolsonaro whose scheme, they said, was for the national armed forces to intervene, restore order and return him to office.
At the time, his attorneys called the over 27-year sentence extremely harsh.
He was also prohibited from seeking elected position until twenty-sixty - eight years after the completion of his term.
The one-time head of state called the court case a political persecution and said it was designed to prevent him running in the 2026 national vote.
