Prince Alwaleed bin Talal was arrested two months ago as part of the crackdown and moved to restricted quarters at the Riyadh Ritz Carlton Hotel with 200 other princes and top officials.

The Saudi authorities have now transferred the prince along with others to the nation's highest security prison Al-Ha’ir – located south of Riyadh, according to Al-Araby Al-Jadeed news.

During his detention, Alwaleed is said to have been hung upside down and beaten.

The numbers detained in the Riz-Carlton fell as they gave into demands from Crown Prince Mohammed bin Salman for restitution payments, but Prince Alwaleed is said to have refused to pay the Government £728million.
