PV International Desk : A new Saudi anti-corruption body has detained 11 princes, four sitting ministers and dozens of former ministers, reports BBC.
The detentions came hours after the new committee, headed by Crown Prince Mohammed bin Salman, was formed by royal decree.
Those detained were not named.
BBC security correspondent Frank Gardner says Prince Mohammed is moving to consolidate his growing power while spearheading a reform program.
It is not clear what those detained are suspected of. However, Saudi broadcaster Al-Arabiya said fresh investigations had been launched into the 2009 Jeddah floods and the outbreak of the Mers virus which emerged in Saudi Arabia in 2012.
The new anti-corruption committee has the power to issue arrest warrants and travel bans, the state-owned Saudi Press Agency (SPA) reported.
Separately, the heads of the Saudi National Guard and the navy were replaced in a series of high-profile sackings.
SPA said King Salman had dismissed National Guard minister Prince Miteb bin Abdullah and navy commander Admiral Abdullah bin Sultan bin Mohammed Al-Sultan.
