The former Brazilian leader has been arrested after authorities concluded he posed a concrete flight risk while under home confinement.
The ex-president was sentenced of plotting a military coup in September and sentenced more than 27 years in prison, but he continued under house arrest pending court reviews.
Brazilian Supreme Court Justice the presiding justice said the move to detain the elderly politician was a preventative measure after recent developments emerged.
This involved trying to remove his electronic bracelet and a invitation to a supporters' gathering that could "allow for a chance to flee".
Judicial Records Show Escape Risks
In a paperwork permitting the custody, the magistrate said intelligence from the facility tracking Bolsonaro's house arrest suggested the one-time head of state's "intention to break the tracking monitor to secure accomplishment in his getaway".
This, it said, would be "facilitated by the confusion caused by the protest called by his child.
His son, Flávio Bolsonaro, who serves as a legislator, called for a gathering of his followers near his father's house to take place on Saturday evening.
The senator wrote on social media on last Friday: Will you battle for your nation, or see it all from your mobile device there on your couch? I urge you to fight with us."
He said the vigil would be so supporters could offer prayers for his health 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 move to diplomatic missions near the dwelling, considering that the inquiries revealed a record of planning to ask for protection through a embassy office", a statement said.
The court filing highlights that the United States embassy in the federal district, Brasilia, is situated around 13km from his dwelling.
International Reactions
His judicial problems have provoked anger from fellow populist conservative United States President Trump, causing him to enact a 50% tariff on Brazilian product imports.
The former president is being held in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the High Court to authorize him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that Bolsonaro be authorized to exit his dwelling for medical treatment, saying he needed frequent medical attention for lung conditions and other illnesses.
Details of Guilty Verdict
He was found guilty of heading a scheme aimed at retaining his authority after he was defeated in the national vote to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plan which involved plans to murder his opponent and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill the presiding judge - the top judicial official who has been overseeing the former president's case.
The scheme was stopped because it failed to get the endorsement of the armed forces officials. His successor was inaugurated without incident on January 1st, 2023.
But a following week, on the eighth of January, many Bolsonaro supporters attacked and damaged official structures in the national capital, the capital city.
The security forces intervened and around 1,500 people were arrested.
The judges found that the rioters had been incited by the former president whose scheme, they said, was for the Brazilian military to take action, restore order and bring him back to power.
At the time, the legal team called the 27 years and three months sentence "absurdly excessive.
He was also banned from seeking elected position until twenty-sixty - eight years after the completion of his term.
The one-time head of state called the legal proceedings a "witch hunt and said it was designed to prevent him running in the 2026 presidential election.
