(AI translated) Chadha Haj Mabrek is a Tunisian journalist who was arrested by plainclothes Tunisian police officers at Instalingo's headquarters and taken into custody on 10 September 2021 as part of the ‘Instalingo affair’. For its part, the Anadolu Agency reports that she was arrested in 2021 by the Tunisian military justice system.

Instalingo is a company based in El Kantaoui, Sousse, specialising in content creation and digital communication. Its premises were raided on 10 September 2021, following reports of its alleged involvement in ‘undermining state security, money laundering and defamation via social media’.

Those targeted also include security officials, bloggers, journalists, businessmen and politicians, including the president of the Ennahdha movement, Rached Ghannouchi, former head of government Hichem Mechichi, and former director of the presidential cabinet, Nadia Akacha. They are accused of ‘conspiracy against state security, attempting to change the regime and spreading defamatory information about the President of the Republic’, in accordance with Articles 61, 62 bis and 67 of the Penal Code.

On 17 September 2021, she was heard by a judge at the Sousse Court of First Instance, who ordered her release pending further investigation. In November 2021, the public prosecutor appealed this decision and a warrant for her arrest was issued.

On 16 June 2023, the investigating judge decided to close the investigation and drop the charges. However, following the public prosecutor's appeal, on 20 July 2023, the indictment division sentenced her to a prison term for ‘undermining state security’. She was arrested the same day at her home in Kélibia.

On 5 February 2025, she was sentenced to five years in prison for attempting to ‘change the form of government’. She was imprisoned in Messaadine prison. The National Union of Tunisian Journalists expressed its solidarity with her after her conviction and announced that it would appeal the decision.
