'Night of the beating': details emerge of Riyadh Ritz-Carlton purge

Exclusive: three years on, some of the Saudi detainees reveal what they say took place

In early November 2017, nearly 400 of Saudi Arabia's most powerful people, among them princes, tycoons and ministers, were rounded up and detained in the Ritz-Carlton hotel, in what became the biggest and most contentious purge in the modern kingdom's history.

The arrests shook the foundations of Saudi society, in an instant turning untouchable establishment figures into targets for arrest. Statuses were discarded, assets seized and business empires upended. A conventional pact between the state and its influential elite was shredded overnight.
