Brazil’s former president Jair Bolsonaro was arrested early Saturday after federal police accused him of attempting to tamper with his court-ordered ankle monitor in an effort to flee the country and avoid beginning a 27-year prison sentence for leading an alleged coup attempt.
The dramatic arrest—ordered by Supreme Court Justice Alexandre de Moraes—came just after midnight, when authorities said Bolsonaro’s tracking device registered a violation. Shortly after, agents entered his Brasília home and took him into custody.
According to a custody report reviewed by The Associated Press, Bolsonaro admitted to officers that he used a soldering iron to try to pry open the device. In court footage also seen by the AP, the former president is heard acknowledging the attempt. His lawyers dispute the account, insisting the monitor had not been tampered with.
Bolsonaro, 70, has been under house arrest since August and was required to wear the device after being deemed a flight risk. De Moraes said the preemptive arrest was necessary to prevent Bolsonaro from escaping amid a rally planned outside his home on Saturday by his son, Sen. Flávio Bolsonaro.
De Moraes warned that the former president was just minutes away from the U.S. Embassy in Brasília—a potential refuge he suggested Bolsonaro might attempt to reach. Investigators also previously uncovered messages linking Bolsonaro to discussions about requesting political asylum in Argentina.
Bolsonaro’s supporters and opponents reacted swiftly. A small group of loyalists gathered outside the federal police headquarters where he is being held, while detractors celebrated online and organized street parties. Police moved to keep both groups apart.
In Washington, President Donald Trump—an ally of Bolsonaro’s—said he was unaware of the arrest until reporters asked him about it. “That’s too bad,” he said, offering no additional comment. He added that he had spoken with Brazilian President Luiz Inácio Lula da Silva the previous night.
Bolsonaro’s legal team criticized the preemptive arrest as baseless, arguing it was triggered by a “prayer vigil,” not an attempt at escape. But the move will now be reviewed by the five-justice Supreme Court panel that convicted Bolsonaro 4–1 in September for attempting to overturn the 2022 election and undermine Brazil’s democracy.
Bolsonaro, who governed from 2019 to 2022, has denied all wrongdoing. He was found guilty of leading an armed criminal organization and attempting the violent abolition of democratic rule. Prosecutors said the coup plot included plans to assassinate Lula, Vice President Geraldo Alckmin and Justice de Moraes.
His arrest could soon transition from preventive to permanent, as local media report he may begin serving his sentence as early as next week after appeals are exhausted.
Political analysts say the move could reshape Brazil’s 2026 presidential race. With Bolsonaro barred from running, his allies are scrambling to preserve his influence.
“This forces the Bolsonaro camp to rethink everything,” said Creomar de Souza, a Brasília-based political risk analyst. “Their entire strategy depended on keeping him politically alive as the symbolic leader of the opposition.”
Bolsonaro’s wife, Michelle, vowed supporters “will not give up on our nation,” while his congressional allies denounced de Moraes’ ruling as an abuse of power.
Lula, attending a G20 summit in South Africa, has not yet commented on the arrest. But senior aides said Bolsonaro’s detention follows months of attempts to intimidate the Supreme Court.
With tensions rising across Brazil, police have increased security around federal buildings in Brasília. More demonstrations—on both sides—are expected in the coming days.
