Former Ennahda member and prime minister Hamadi Jebali was detained by Tunisian police on Thursday on charges of money laundering, according to his attorney, who also served as a prominent member of the party.

According to a post by his relatives on Facebook, police in the city of Sousse confiscated Jebali’s and his wife’s phones and took them both away.

Jebali’s arrest raises opposition concerns over the human rights record since President Kais Saied seized control of executive power last year, in a move his opponents called a coup.

The Interior Ministry declined to comment on Jebali’s arrest. The ministry called a press conference for Friday, without giving any details.

Jebali’s defence team said they met him at his detention centre of the investigation into terrorism crimes.

“Jebali told us he will not answer the investigators’ questions and he entered into a hunger strike as the issue has a political motivation and nothing to do with money laundering”, Jebali’s lawyer Mokhtar Jemai said.

Ennahda was the biggest party in Tunisia’s parliament before President Kais Saied dissolved the assembly and seized executive powers last year, a move the party and other critics condemned as a coup. Saied said the move was temporary and was needed to save Tunisia from what he saw as a corrupt, self-serving elite.

“The president is personally responsible for Jebali’s physical and psychological well-being,” his family said in the Facebook post, and called on civil society and human rights organizations “to stand up against these repressive practices”.

Jebali was prime minister in 2012 and resigned in 2013 following a political crisis.

Earlier this year, police arrested Noureddine Bhiri, the vice president of Ennahda party for more than two months before releasing him without any charges being brought.

Saied’s opponents say he is waging a campaign through the police and the judiciary to target his opponents, but he denies this and says he is not a dictator.
