Bolsonaro has been arrested after authorities determined he posed a definite escape threat while under house arrest.
The former head of state was found guilty of plotting a military coup in the ninth month and sentenced more than 27 years in jail, but he was staying under house arrest pending legal challenges.
Brazilian Supreme Court Justice the presiding justice said the move to detain the 70-year-old politician was a preventative measure after fresh information emerged.
This involved trying to remove his electronic bracelet and a invitation to a public vigil that could "allow for a possible escape.
Judicial Records Show Escape Concerns
In a filing authorising the detention, Justice Moraes said intelligence from the facility tracking the former president's confinement suggested the one-time head of state's plan to remove the tracking monitor to secure accomplishment in his escape.
This, it said, would be "facilitated by the disorder caused by the demonstration called by his child.
His son, Flávio, who holds office as a senator, called for a assembly of his followers near Bolsonaro's home to take place on the weekend.
The senator wrote on online platforms on last Friday: "Are you going to fight for your homeland, or see it all from your mobile device there on your sofa? I call on you to battle with us."
He said the vigil would be so supporters could "pray for his health and for the reestablishment of democratic governance in our country."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of his transfer to foreign missions near the dwelling, considering that the investigations revealed a background of organizing to request asylum through a consular facility", a statement said.
The judicial paperwork emphasizes that the United States embassy in the national capital, the capital city, is located around 8 miles from the former president's residence.
Global Responses
The former president's legal troubles have provoked anger from fellow right-wing populist United States President President Trump, leading him to impose a half-rate duty on goods coming from Brazil.
Bolsonaro is being detained in a national police facility in Brazil's capital city and will undergo a detention review on the next day.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the High Court to allow him to serve his whole jail sentence under house arrest, with digital surveillance.
They also requested that he be authorized to leave his home for healthcare, saying he required regular treatment for pulmonary infections and other ailments.
Background on Conviction
The former president was found guilty of leading a scheme aimed at keeping him in power after he was defeated in the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which involved plans to assassinate Lula and his running partner, Alckmin, and to imprison and murder Justice Moraes - the Supreme Court justice who has been presiding over his judicial proceedings.
The plot was prevented because it couldn't obtain the backing of the armed forces officials. The current president was sworn in without incident on January 1st, 2023.
But a seven days after, on 8 January, many Bolsonaro supporters attacked and damaged public facilities in the capital, Brazil's capital.
The police stepped in and around approximately 1,500 persons were taken into custody.
The judges found that the demonstrators had been provoked by the former president whose strategy, they said, was for the Brazilian military to intervene, reestablish control and bring him back to power.
At the moment, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also barred from running for public office until the year 2060 - eight years after the end of his sentence.
The one-time head of state called the court case a targeted investigation" and said it was intended to stop him competing in the next presidential race.
