Sewol.- Two Coast Guard officials have been arrested on charges of failing to carry out their duties at the time of the Sewol-ho ferry disaster . The district court in the southwestern city of Gwangju says one is a 43-year-old center leader of the Jindo V-T-S control Center and the other a 39-year-old C-C-T-V footage administrator. The court says the control center was unable to detect early signs of unusual activity over the waters they were monitoring on the morning of April 16th, the day of the ferry sank. The control center was also found to have fraudlently written the transcipt of communcations between the center and crew members onboard the Sewol-ho. The investigation is also looking into whether the center leader ordered his subordinates to erase weeks of C-C-T-V footage inside the center that would indicate a negligence of duty.
