Bolsonaro has been taken into custody after authorities concluded he posed a serious risk of fleeing while under house arrest.
The one-time leader was sentenced of planning a military coup in last fall and sentenced more than over two decades in jail, but he continued under confinement pending appeals.
Brazilian Supreme Court Justice Justice Moraes said the move to detain the 70-year-old politician was a precautionary step after recent developments came to light.
This included seeking to disable his tracking device and a call for a demonstration that could facilitate a possible escape.
Legal Document Reveals Flight Fears
In a filing authorising the arrest, Justice Moraes said intelligence from the unit overseeing 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 confusion caused by the gathering called by his son.
His child, Flávio, who works as a congressional representative, called for a assembly of his supporters near the former president's residence to take place on Saturday evening.
The senator wrote on digital networks on the previous day: Do you plan to struggle for your nation, or watch it all from your phone there on your sofa? I urge you to struggle with us."
He said the gathering would be so followers could "pray for his physical condition and for the restoration of democratic rule in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's determination was the potential of Bolsonaro's transfer to embassies near the dwelling, considering that the investigations revealed a background of arranging to seek refuge through a diplomatic representation", a announcement said.
The judicial paperwork underscores that the American diplomatic mission in the capital, Brasilia, is located around 13km from Bolsonaro's home.
Global Responses
The former president's legal troubles have provoked anger from fellow conservative nationalist United States President Trump, causing him to enact a 50% tariff on goods coming from Brazil.
The former president is being detained in a national police facility in Brazil's capital city and will undergo a custody hearing on the following day.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the High Court to authorize him to fulfill his full incarceration period under domestic detention, with tracking devices.
They also requested that the former president be permitted to leave his home for medical care, saying he needed ongoing care for lung conditions and other ailments.
Background on Conviction
Bolsonaro was determined responsible of heading a conspiracy aimed at maintaining his control after he failed to win the 2022 election to his left-wing rival, President Lula.
Supreme Court justices said that he had knowledge of a scheme which included plans to kill Lula and his VP candidate, Alckmin, and to detain and kill Justice Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The conspiracy was prevented because it couldn't obtain the backing of the army and air force commanders. The current president was inaugurated without problem on January 1st, 2023.
But a following week, on January 8th, numerous his followers stormed and vandalised official structures in the national capital, Brasília.
The security forces stepped in and around 1,500 people were arrested.
The justices found that the demonstrators had been provoked by him whose scheme, they said, was for the country's army to take action, reestablish control and return him to office.
At the moment, his attorneys called the 27 years and three months sentence extremely harsh.
He was also prohibited from running for public office until twenty-sixty - a decade minus two years after the completion of his term.
The ex-leader called the court case a targeted investigation" and said it was aimed at blocking him running in the 2026 presidential election.
