Sylvia Bongo, wife of ousted Gabonese President Ali Bongo, is being held in pre-trial detention on allegations of the embezzlement of public funds, her lawyer says.
She had been under house arrest since the 30 August coup.
But after a long hearing in front of a judge it was decided that she should be detained in jail.
Her lawyer, Francois Zimeray, criticised the decision and is quoted as calling it arbitrary and illegal.
Mrs Bongo is facing charges of money laundering, forgery and the falsification of documents. She has not made any public comment on the charges.
The BBC understands she will appear in court in 10 days’ time for a further hearing, where her lawyer can make a case for her release.
The former head of Gabon’s cabinet, Brice Laccruche Alihanga, who was jailed four years ago on charges of embezzlement, misappropriation of public funds and money laundering, gave evidence at Mrs Bongo’s hearing.
The allegations against her are closely linked to the former cabinet chief.
In 2019, the former first lady is alleged to have been behind a major anti-corruption campaign, dubbed Operation Scorpion, which saw several government officials arrested and jailed, including Alihanga, and which some Gabonese described as a witch hunt.
