The ousted board of the Philippines' biggest casino said on Monday it is suing Japanese tycoon Kazuo Okada and his partners, accusing them of coercion and other misconduct in what it said was a "violent and illegal" seizure of the gambling resort last week. In a dramatic turn of events in a long-running dispute over control of Tiger Resort, Leisure & Entertainment which is owned by Japan's Universal Entertainment Corp, Okada's camp took physical control of the $3.3 billion casino known as Okada Manila on May 31 with the help of private security guards and local police.
