Japan's Coast Guard has arrested a crew member who was in charge when a Russian vessel collided with a Japanese fishing boat in the Sea of Okhotsk, killing three people on board.
A 38-year-old third officer of the Amur was arrested shortly before 10 a.m. on Monday on suspicion of professional negligence resulting in death and of endangering passing traffic through negligence.
On May 26, the Amur was heading to the port of Mombetsu when it collided with the Daihachi Hokkomaru, which had been fishing for crabs. The Japanese boat turned over, killing three of its five crew members.
Japanese authorities interviewed the officials involved and analyzed the ships' navigation routes.
The investigation reportedly revealed that the Russian sailor had caused the three deaths by not keeping a proper lookout to prevent a collision.
Authorities will continue investigating to find out what happened at the time of the collision.
