MOKPO, South Korea (AP) — The captain of the ferry that sank off South Korea, leaving more than 300 missing or dead, was arrested early Saturday on suspicion of negligence and abandoning people in need. Two crew members also were taken into custody, including a mate who a prosecutor said was steering in challenging waters unfamiliar to her when the accident occurred.

Prosecutors said the ferry captain, Lee Joon-seok, 68, was arrested early Saturday along helmsman Cho Joon-ki, 55, and the ship’s 25-year-old third mate. Another helmsman, Park Kyung-nam, identified the mate as Park Han-kyul.
