Saudi Arabia has released ten businessmen arrested in the kingdom's so-called crackdown on corruption some 15 months ago, the Prisoners of Conscience rights group said on Twitter.
"The Saudi authorities have released ten Ritz-Carlton detainees over the past two days" the account posted without revealing its sources.
According to the account, the released detainees included Ethiopian-born billionaire, Sheikh Mohammed Hussein Al- Amoudi who was arrested in November 2017.
The Saudi authorities did not comment on the report, but Ethiopian television confirmed earlier that Al- Amoudi had been released.
The Saudi authorities arrested dozens of former and current princes, businessmen and senior officials and detained at the Ritz-Carlton Hotel in Riyadh in early November 2017.
At the time, Saudi opponents said the campaign is a "trick" to bolster Saudi Crown Prince Mohammed bin Salman's influence.
In the following few months, the Saudi authorities released a number of the detained businessmen after financial settlements that reached 400 billion riyals, equivalent to about $107 billion.
