South Korea hunts Sewol ferry owner Yoo Byung-Eun

South Korean President Park Geun-hye has called for police to do more to track down the owner of a ferry which capsized in March, leaving more than 300 people dead.

Ms Park said she could not understand how Yoo Byung-Eun and his son had still not been found.

Fifteen crew members from the ferry, including the captain, are standing trial in connection with the deaths.
