The Russian captain of a cargo ship that collided with a U.S. tanker in the North Sea pleaded not guilty to the manslaughter of one of his crew at a U.K. court hearing on Friday. Vladimir Motin, 59, from St. Petersburg, appeared by video link from prison for the pretrial hearing at London’s Central Criminal Court. Assisted by a Russian interpreter, he denied a charge of gross manslaughter over the death of 38-year-old Mark Angelo Pernia.
