A mobile phone video, shot by one of the teenagers who died in the South Korean ferry sinking two weeks ago, has been released by his family.
It shows the boat's crew instructing passengers to stay in their cabins, as the situation worsens.
All crew involved in navigating the ferry are now in custody and the coast guard is under investigation over whether its personnel could have tried harder to rescue passengers.
The Sewol ferry sank en route from Incheon to the island of Jeju on April 16, killing up to 300 people.
