The company that owned the South Korean ferry which sank last week, killing possibly hundreds of people, sprang out of a shipping to cosmetics empire founded by a businessman who was jailed for fraud and then went bankrupt. The founder of the predecessor company, Yoo Byung-un, once likened his 1997 bankruptcy proceedings to a captain going down with his ship. An investment vehicle run by his two sons and its shipbuilding affiliate are now the majority owners of Chonghaejin Marine Co. Ltd, the operator of the ferry that capsized. There is no suggestion that last Wednesday's accident was in any way linked to the company's chequered history. But Yoo and his two sons have been barred from leaving South Korea as investigators seek to establish what led to the fatal sinking of the Sewol ferry.
