Bolsonaro has been arrested after authorities found he posed a definite escape threat while under domestic detention.
The ex-president was sentenced of orchestrating a armed takeover in the ninth month and given more than a 27-year term in jail, but he was staying under confinement pending court reviews.
Brazilian Supreme Court Justice Alexandre de Moraes said the move to detain the elderly politician was a safety action after "new facts" came to light.
This involved trying to remove his tracking device and a summons to a public vigil that could enable a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the custody, Justice Moraes said information from the centre monitoring Bolsonaro's house arrest suggested the former leader's plan to remove the tracking monitor to ensure success in his getaway".
This, it said, would be "facilitated by the chaos caused by the protest called by his son.
His child, his son Flávio, who holds office as a legislator, called for a gathering of his backers near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on online platforms on last Friday: "Are you going to fight for your homeland, or observe everything from your smartphone there on your sofa? I call on you to battle with us."
He said the demonstration would be so backers could seek divine intervention for his physical condition and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the chance of his move to foreign missions near the residence, considering that the inquiries revealed a history of planning to request asylum through a consular facility", a statement said.
The legal document emphasizes that the United States embassy in the national capital, Brazil's capital, is positioned around 8 miles from Bolsonaro's home.
International Reactions
The former president's legal troubles have provoked anger from fellow right-wing populist US President Donald Trump, causing him to enact a fifty percent tax on imports of Brazilian goods.
Bolsonaro is being held in a federal law enforcement building in Brazil's capital city and will have a detention review on the next day.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the Top Court to permit him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also requested that he be allowed to depart his residence for medical treatment, saying he demanded ongoing care for lung conditions and other illnesses.
Background on Conviction
The former president was convicted of heading a scheme aimed at retaining his authority after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
Top judicial officials said that he had knowledge of a plan which involved plans to murder the current president and his VP candidate, his vice-presidential candidate, and to detain and kill Justice Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The plot was prevented because it didn't receive the endorsement of the military leaders. The current president was took office without problem on the first day of 2023.
But a seven days after, on 8 January, numerous his backers stormed and vandalised public facilities in the federal district, Brazil's capital.
The law enforcement stepped in and around fifteen hundred individuals were arrested.
The judges found that the rioters had been encouraged by Bolsonaro whose plan, they said, was for the country's army to take action, bring back stability and return him to office.
At the period, the legal team called the over 27-year sentence unreasonably severe".
He was also barred from campaigning for office until twenty-sixty - eight years after the conclusion of his imprisonment.
The one-time head of state called the trial a political persecution and said it was intended to stop him competing in the 2026 presidential election.
