Some of Saudi Arabia's most powerful men were arrested in October as part of a fight against corruption. The government freezed the accounts of the more than three dozen men totalling $33 billion of net worth. The series of arrests has implicated the country's richest people, including Prince Alwaleed bin Talal, Bakr Binladin, Mohammed Al Amoudi, Saleh Kamel and Nasser Al Tayyar. Prince Alwaleed bin Talal is No. 50 on the Bloomberg Billionaires Index ranking of the world's 500 richest people, with $19 billion. Two of the four Saudis on the Bloomberg index haven't been detained, hotel magnate Mohamed bin Issa Al Jaber, who has an $8.3 billion fortune, and Prince Sultan Bin Mohammed Al Kabeer, the biggest individual shareholder in food processor Almarai Co., who has $4.7 billion.
