Country's largest oil company CEO questioned

The head of Russia's largest oil company was summoned Friday to the General Prosecutor's Office to answer questions connected with the detention of a close business associate for alleged fraud. Mikhail Khodorkovsky, chief executive of Russia's Yukos oil company and Russia's richest man with $8 billion according to Forbes magazine, spent just under two hours being questioned. Khodorkovsky said no questions were connected to Yukos' economic activity. Khodorkovsky's associate, billionaire Platon Lebedev, was arrested this week.
