Scores of people who lost their savings in one of Tunisia's largest money scams protested Saturday in front of the interior ministry to demand justice.

The scam revealed on Friday concerns some 90,000 people, mostly from the lower middle class, lured by high gains promised by an investment company called Yosr Development.

On Friday, dozens of angry investors looted the house of the company owner's mother in the capital Tunis in a bid to recover some of their losses.

Meanwhile, Adel Dridi, head of Yosr Development, was arrested Saturday by judicial police near the northeastern port city of Sousse, Radio Mosaique FM reported.

He had previously been suspended from traveling by a court order issued 3 months ago.

An interior ministry spokesman said Adel Dridi, now being questioned, will soon appear in a court.

The swindle, which is said to have raised hundreds of millions of Tunisian dinars (1 Tunisian dinar = 0.609 U.S. dollar), has been extensively covered by Tunisian media.

According to financial experts, such money scams have been proliferating since start of the upheaval that led to the ouster of former President Zine El Abidine Ben Ali on Jan. 14, 2011.
