Bolsonaro has been taken into custody after authorities determined he posed a definite escape threat while under house arrest.
The former head of state was convicted of planning a government overthrow in the ninth month and sentenced more than 27 years in prison, but he remained under home detention pending legal challenges.
Brazilian Supreme Court Justice the presiding justice said the action to imprison the septuagenarian politician was a safety action after recent developments were revealed.
This included trying to remove his ankle monitor and a invitation to a public vigil that could "allow for a chance to flee".
Legal Document Reveals Flight Fears
In a filing authorising the custody, the judge said data from the centre monitoring the former president's confinement suggested the former leader's plan to remove the electronic ankle bracelet to ensure success in his flight.
This, it said, would be assisted by the disorder caused by the demonstration called by his offspring.
His son, Flávio Bolsonaro, who serves as a legislator, called for a meeting of his supporters near the former president's residence 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 smartphone there on your couch? I urge you to struggle with us."
He said the demonstration would be so backers could seek divine intervention for his well-being and for the restoration of democratic rule in our land."
Embassy Asylum Concerns
Part of Justice Moraes's decision was the chance of Bolsonaro's "relocation to foreign missions near the residence, considering that the investigations revealed a background of organizing to request asylum through a consular facility", a declaration said.
The legal document emphasizes that the American diplomatic mission in the national capital, Brasilia, is positioned around approximately 13 kilometers from Bolsonaro's home.
