Saudi Arabia’s crown prince is stepping up pressure on detained members of the country’s elite resisting his demands for billions of dollars in payments—moving them from a luxury hotel to prison, according to people familiar with the move, and threatening them with prosecution. The kingdom has wrested about $100 billion from most of the 350 Saudi royals and prominent business people arrested in what the Saudi leader has said is a corruption purge, Saudi officials said. The public prosecutor’s office said this week that officials were moving ahead with plans for trials of 95 holdouts who were still detained and have declined to pay what the government describes as financial settlements. Many detained Saudi elites have been moved from the Ritz-Carlton Hotel in the Saudi capital Riyadh, shown above in May, to al Hayer prison to the south of the city, shown below, in 2015.
