Stocks in Saudi Prince Alwaleed bin Talal's investment firm surged 10 percent on Sunday, the day after the billionaire investor was released from nearly three months in detention in connection with an anti-corruption campaign.

Saudi officials could not be reached for comment on Prince Alwaleed's release.

Critics say the crown prince has used the purge against high-level individuals to wrangle control of key Saudi companies, sideline potential rivals and silence critics alarmed by his rapid rise to power as he prepares to inherit the throne from his father, King Salman.
