Four crew members of the ferry that capsized on April 16 were indicted for manslaughter by South Korean prosecutors, a senior prosecutor said, according to Reuters.
The ferry Sewol disaster led to the death of 281 people.
Eleven other surviving crew members of the Sewol were indicted for negligence, the news agency reported. The crew of the ferry has been under criminal investigations after they were believed to have escaped the ship before many of passengers did.
On Wednesday morning, CNN reported that divers had recovered five more bodies from the wreck of the Sewol. Twenty-three people still remain missing, but hopes of finding other survivors have vanished.
Most of the dead and missing are students, all from the same high school, who were traveling on the ferry to the resort island Jeju. The boat sank off the country's southwestern coast.
