Saudi Arabia’s public prosecutor has begun processing the cases of 56 men detained in the country’s sweeping anti-corruption purge late last year, an official said on Sunday.

The 56 are still in Saudi government custody after failing to be exonerated or reach financial settlements with the government.

The shock crackdown in November 2017 saw a new Supreme Anti-Corruption Committee round up 381 corruption suspects on Crown Prince Mohammed bin Salman’s orders, with many confined and interrogated.

Just 30 or so of the men’s identities were released.

The list of names included top officials, members of the Saudi royal family, and global investor Prince Alwaleed bin Talal.

More than 2,000 bank accounts were frozen and private jets were grounded as detainees were rounded up and, in many cases, held in Riyadh’s opulent Ritz-Carlton hotel.

In January, Saudi Arabia’s attorney general released a statement saying it had completed its review of cases and would release all those who had paid settlements or against whom it did not have enough evidence.
