The Russian captain of a cargo ship that collided with a U.S. tanker earlier this week appeared in a U.K. court Saturday where he was remanded in custody over the death of a crew member, who is missing and presumed dead.

British police have charged the Russian captain of a cargo ship that crashed into a United States fuel tanker in the North Sea this week with manslaughter and gross negligence over the death of a crew member.

The captain of the Solong cargo ship who was arrested after crashing into an oil tanker off the coast of England is a Russian national, the ship’s owner Ernst Russ said Wednesday.
