Bolsonaro has been detained after authorities determined he posed a definite escape threat while under house arrest.
The former head of state was sentenced of planning a armed takeover in the ninth month and sentenced more than over two decades in incarceration, but he was staying under home detention pending court reviews.
High Court Judge Justice Moraes said the action to imprison the septuagenarian politician was a safety action after recent developments were revealed.
This encompassed seeking to disable his ankle monitor and a invitation to a demonstration that could facilitate a chance to flee".
Court Filing Details Flight Fears
In a filing authorising the custody, Justice Moraes said data from the centre monitoring Bolsonaro's house arrest suggested the ex-president's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be assisted by the confusion caused by the gathering called by his offspring.
His child, his son Flávio, who holds office as a congressional representative, called for a meeting of his backers near the former president's residence to take place on Saturday evening.
The senator wrote on digital networks on Friday: Do you plan to struggle for your homeland, or observe everything from your smartphone there on your sofa? I invite you to battle with us."
He said the vigil would be so followers could offer prayers for his physical condition and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the judge's determination was the chance of his move to embassies near the residence, considering that the inquiries revealed a record of organizing to ask for protection through a consular facility", a statement said.
The court filing highlights that the American diplomatic mission in the national capital, Brazil's capital, is situated around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have generated frustration from fellow populist conservative US President President Trump, leading him to impose a 50% tariff on Brazilian product imports.
Bolsonaro is being held in a Federal Police station in Brasilia and will experience a custody hearing on Sunday.
Recent Legal Requests
It was only on Friday that the his legal team asked the Top Court to authorize him to complete his entire prison term under home confinement, with electronic monitoring.
They also requested that he be allowed to leave his home for medical treatment, saying he needed frequent medical attention for lung conditions and other ailments.
Background on Conviction
He was convicted of heading a conspiracy aimed at maintaining his control after he failed to win the 2022 election to his left-wing rival, President Lula.
High Court judges said that he knew of a scheme which involved plans to assassinate the current president and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been presiding over the former president's case.
The scheme was prevented because it didn't receive the backing of the military leaders. His successor was took office without issue on the first day of 2023.
But a seven days after, on the eighth of January, thousands of his backers attacked and damaged public facilities in the capital, Brazil's capital.
The police took action and around fifteen hundred individuals were taken into custody.
The justices found that the protesters had been encouraged by him whose strategy, they said, was for the national armed forces to step in, restore order and bring him back to power.
At the period, Bolsonaro's lawyers called the decades-long sentence unreasonably severe".
He was also banned from seeking elected position until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the legal proceedings a political persecution and said it was intended to stop him running in the next presidential race.
