Senior Saudi Prince Miteb bin Abdullah, a former National Guard head once seen as a contender to the throne, has been freed after more than three weeks in detention, according to Twitter messages by royal family members on Tuesday, Reuters reported.

“Almighty, thanks be to you ...” wrote Abeer bint Khaled bin Abdullah, a royal family member, in a posting on her Twitter account. Posting an apparent file photo of Prince Miteb, she added: “May God give you long life, long life full of health, and keep you for us.”

Miteb was among dozens of royal family members, ministers and current and former senior officials who were rounded up in a graft inquiry at least partly aimed at strengthening the power of Crown Prince Mohammed bin Salman.
