Tunisian authorities have jailed a prominent ally of the longtime president who was ousted earlier this year.
The state news agency TAP said Thursday that Abderrahim Zouari was jailed after questioning by an investigating judge in the capital's main courthouse. It is unclear what charges he faces.
Zouari headed different government ministries and for several years led the country's ruling party, the RCD or Constitutional Democratic Assembly.
The RCD under President Zine El Abidine Ben Ali quashed dissent and imprisoned political opponents.
Ben Ali was ousted by a popular revolt in January. Tunisia's protest sparked uprisings around the Arab world.
The RCD has since been dissolved. Zouari is the latest of several Ben Ali allies to have been arrested.
