A second California man has been arrested on suspicion of trying to kill himself by causing a train crash. Tigran Kashkarian, 25, was arrested on Thursday after a car chase that started in Irvine near Los Angeles, police say. On Wednesday Juan Manuel Alvarez - also described as suicidal - was accused of murder after he left his car on a track, causing a crash that killed 11. Kashkarian's bid was a copycat act, police say. They say they were told about a four-wheel drive vehicle that was parked diagonally across the tracks in Irvine. Police say they tried to negotiate with Mr Kashkarian, but he drove off, starting a "slow speed" pursuit. Kashkarian agreed to give himself up after a 30-minute discussion with officers on his mobile phone, a police spokesman said.
