Bolsonaro has been taken into custody after authorities found he posed a concrete flight risk while under house arrest.
The one-time leader was convicted of orchestrating a government overthrow in the ninth month and handed more than a 27-year term in jail, but he continued under confinement pending appeals.
High Court Judge the presiding justice said the decision to arrest the 70-year-old politician was a safety action after "new facts" came to light.
This involved trying to remove his ankle monitor and a call for a supporters' gathering that could "allow for a possible escape.
Court Filing Details Flight Fears
In a filing authorising the detention, the judge said information from the centre monitoring the former president's confinement suggested the former leader's aim to disable the surveillance device to guarantee victory in his escape.
This, it said, would be made easier by the confusion caused by the gathering called by his child.
His son, his son Flávio, who serves as a congressional representative, called for a assembly of his supporters near Bolsonaro's home to take place on Saturday evening.
His son wrote on digital networks on the previous day: "Are you going to fight for your country, or see it all from your phone there on your couch? I urge you to struggle with us."
He said the demonstration would be so supporters could seek divine intervention for his well-being and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of the judge's determination was the chance of Bolsonaro's move to diplomatic missions near the home, considering that the investigations revealed a history of organizing to ask for protection through a embassy office", a declaration said.
The judicial paperwork underscores that the US embassy in the national capital, the capital city, is positioned around 8 miles from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist United States President Trump, leading him to implement a half-rate duty on imports of Brazilian goods.
The former president is being kept in a national police facility in the capital and will experience a imprisonment assessment on the following day.
Recent Legal Requests

Details of Guilty Verdict
