Influential businessman Prince Al-Waleed bin Talal is reportedly among royals arrested in Saudi Arabia on Saturday, hours after the launch of a corruption-fighting commission.The billionaire, whose company owns holdings in Twitter, News Corps and Citigroup, is reportedly facing corruption charges, Saudi media reported, but there was no official confirmation. The prince, who is also primary owner of TV network Rotana, was not immediately reachable for comment.Earlier state-owned broadcaster Al Arabiya TV reported 10 princes and dozens of former government ministers has been arrested in an anti-corruption sting.

An aviation source told AFP that security forces had grounded private jets in the Red Sea city of Jeddah, potentially to prevent any high-profile figures from leaving.

"The breadth and scale of the arrests appears to be unprecedented in modern Saudi history," said Kristian Ulrichsen, a fellow at the Baker Institute for Public Policy at Rice University.

"The reported detention of Prince Al-Waleed bin Talal, if true, would send shockwaves through the domestic and international business community."
