A sweeping anti-corruption drive in Saudi Arabia has generated an estimated $106.7bn (£75.6bn) in settlements, the kingdom’s attorney general has said.

Sheikh Saud al-Mojeb said 56 of the 381 people called in for questioning since 4 November remained in custody.

The others had been cleared or admitted guilt and handed over properties, cash, securities and other assets, he added.

Sheikh Mojeb did not name any of those involved, but they reportedly include princes, ministers and businessmen.

In recent days, the billionaire investor Prince Alwaleed bin Talal and Alwalid al-Ibrahim, owner of the Arab satellite television network MBC, were released from detention at the Ritz-Carlton Hotel in Riyadh’s diplomatic quarter.
