Manhunt for tycoon owner of sunken ferry

South Korea is offering a reward for information about a mysterious missing billionaire who authorities say owns a ferry that sank last month, leaving more than 300 people dead or missing.

The disappearance of Yoo Byung-eun and his son has caused a media frenzy in South Korea. Yoo is a member of a church that critics call a cult and have linked to a 1987 mass suicide.

Yoo, 73, was thought to be holed up in a sprawling church compound near Seoul, and there was a tense, days-long stand-off between police and hundreds of church followers, some of whom reportedly threatened to die as martyrs.
