Bolsonaro has been detained after authorities found he posed a definite escape threat while under domestic detention.
The one-time leader was convicted of planning a government overthrow in last fall and handed more than over two decades in jail, but he was staying under house arrest pending court reviews.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the elderly politician was a preventative measure after "new facts" emerged.
This involved trying to remove his electronic bracelet and a summons to a demonstration that could "allow for a possible escape.
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, the judge said data from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's "intention to break the surveillance device to ensure success in his flight.
This, it said, would be made easier by the chaos caused by the gathering called by his son.
His offspring, his son Flávio, who serves as a congressional representative, called for a gathering of his backers near the former president's residence to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your homeland, or watch it all from your phone there on your settee? I urge you to battle with us."
He said the gathering would be so followers could "pray for his health and for the reestablishment of democratic governance in our land."
Embassy Asylum Concerns
Part of the magistrate's ruling was the chance of his move to foreign missions near the residence, considering that the investigations revealed a background of organizing to request asylum through a diplomatic representation", a declaration said.
The judicial paperwork highlights that the US embassy in the capital, the capital city, is situated around 13km from the former president's residence.
International Reactions
His judicial problems have drawn the ire of fellow right-wing populist American leader Trump, prompting him to impose a 50% tariff on Brazilian product imports.
The former president is being detained in a national police facility in Brazil's capital city and will have a imprisonment assessment on the next day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the Top Court to permit him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also requested that he be authorized to depart his residence for medical treatment, saying he required regular treatment for pulmonary infections and other illnesses.
Context of Sentencing
Bolsonaro was found guilty of heading a plot aimed at maintaining his control after he failed to win the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he had knowledge of a plan which included plans to murder Lula and his VP candidate, Alckmin, and to arrest and execute the presiding judge - the top judicial official who has been overseeing Bolsonaro's trial.
The scheme was stopped because it couldn't obtain the support of the army and air force commanders. Lula was inaugurated without issue on the first day of 2023.
But a week later, on the eighth of January, numerous Bolsonaro supporters invaded and destroyed government buildings in the federal district, the capital city.
The security forces took action and around approximately 1,500 persons were arrested.
The justices found that the demonstrators had been encouraged by the former president whose strategy, they said, was for the national armed forces to intervene, reestablish control and return him to office.
At the time, the legal team called the 27 years and three months sentence extremely harsh.
He was also banned from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The ex-leader called the legal proceedings a "witch hunt and said it was designed to prevent him participating in the next presidential race.
