Bolsonaro, who has been under house arrest since August, was transferred to detention on Saturday, his lawyer said.

“He has been imprisoned, but I don’t know why”, Celso Vilardi, one of his lawyers, told the AFP news agency. A close aide told The Associated Press news agency that the embattled former leader was taken to the police headquarters in the capital, Brasilia. Bolsonaro’s aide Andriely Cirino confirmed to AP that the arrest took place at about 6am (03:00 GMT) on Saturday. The force said in a short statement, which did not name Bolsonaro, that it acted on the request of Brazil’s Supreme Court.

Neither Brazil’s federal police nor the Supreme Court provided more details at the time of publication.

The 70-year-old former president was taken from his house in a gated community in the upscale Jardim Botanico neighbourhood to the federal police headquarters, Cirino said. Local media reported that Bolsonaro, who was Brazil’s president from 2019 to 2022, was expected to begin serving his sentence sometime next week after the far-right leader exhausted all appeals of his conviction for leading a coup attempt.

The 70-year-old Bolsonaro’s legal team had previously argued that he should serve his 27-year sentence for a botched coup bid in 2022 at home, arguing imprisonment would pose a risk to his health. Bolsonaro was convicted in September over his bid to prevent President Luiz Inacio Lula da Silva from taking power following the 2022 election, which he lost.

The effort saw crowds of rioters storm government buildings a week after Lula’s inauguration, evoking comparisons with the January 6 riot at the United States Capitol after his close ally, President Donald Trump, lost the 2020 election to Joe Biden. Trump has branded the prosecution of his far-right ally a “witch-hunt” and made it a major issue in US relations with Brazil, imposing stiff tariffs on the country as a form of retribution.
