33 relatives of Tunisia's toppled former President Zine El Abidine Ben Ali have been arrested in recent days, state television reported Thursday.
Television pictures showed footage of watches, jewelry and international credit cards seized during raids on the family members' properties.
Ben Ali fled the country for Saudi Arabia Friday following weeks of unrest.
On Wednesday, officials opened an investigation against the former president and his family for having allegedly plundered the country's resources.
The charges include illegal property acquisitions and currency transfers. Those targeted included Ben Ali, his wife Leila Trabelsi, her brothers and sons and their children.
