The former Brazilian leader has been taken into custody after authorities determined he posed a concrete flight risk while under home confinement.
The former head of state was sentenced of planning a military coup in the ninth month and given more than over two decades in prison, but he was staying under home detention pending appeals.
Top Judicial Official Alexandre de Moraes said the move to detain the 70-year-old politician was a precautionary step after fresh information were revealed.
This involved seeking to disable his electronic bracelet and a invitation to a supporters' gathering that could "allow for a potential flight.
Court Filing Details Flight Fears
In a document approving the custody, Justice Moraes said data from the centre monitoring Bolsonaro's house arrest suggested the former leader's aim to disable the electronic ankle bracelet to ensure success in his getaway".
This, it said, would be made easier by the disorder caused by the demonstration called by his child.
His child, Flávio Bolsonaro, who serves as a legislator, called for a assembly of his followers near the former president's residence to take place on Saturday night.
His son wrote on digital networks on Friday: "Are you going to fight for your nation, or watch it all from your mobile device there on your couch? I urge you to fight with us."
He said the demonstration would be so backers could "pray for his physical condition and for the restoration of democratic rule in our land."
Foreign Shelter Risks
Part of Justice Moraes's determination was the potential of Bolsonaro's move to foreign missions near the residence, considering that the inquiries revealed a record of arranging to ask for protection through a diplomatic representation", a declaration said.
The court filing highlights that the United States embassy in the federal district, Brasilia, is located around 8 miles from the former president's residence.
International Reactions
His judicial problems have generated frustration from fellow populist conservative American leader Trump, prompting him to impose a fifty percent tax on goods coming from Brazil.
The former president is being held in a national police facility in Brazil's capital city and will have a detention review on the next day.
Recent Judicial Appeals
It was only on Friday that the former president's lawyers asked the High Court to allow him to complete his entire prison term under domestic detention, with digital surveillance.
They also requested that Bolsonaro be authorized to exit his dwelling for medical treatment, saying he needed regular treatment for pulmonary infections and other health problems.
Background on Conviction
He was found guilty of orchestrating a plot aimed at maintaining his control after he lost the presidential race to his ideological adversary, 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 imprison and murder the presiding judge - the top judicial official who has been presiding over the former president's case.
The conspiracy was thwarted because it couldn't obtain the backing of the military leaders. The current president was took office without problem on the first day of 2023.
But a seven days after, on the eighth of January, numerous his followers attacked and damaged government buildings in the national capital, the capital city.
The police took action and around 1,500 people were taken into custody.
The judges found that the demonstrators had been incited by Bolsonaro whose strategy, they said, was for the country's army to step in, restore order and reinstate his authority.
At the time, his attorneys called the 27 years and three months sentence extremely harsh.
He was also barred from campaigning for office until 2060 - eight years later after the completion of his term.
The one-time head of state called the court case a political persecution and said it was intended to stop him competing in the 2026 presidential election.
