The parents of a South Korean man killed by a train in Tokyo on Jan. 26 have applied to the government for workers' insurance, the man's former employer said Wednesday.

The couple filed the insurance application with the Shinjuku Labor Standards Inspection Office to cover the death of their son, Lee Su Hyon, who was killed while attempting to rescue a drunken Japanese man who had fallen onto the tracks at JR Shin-Okubo Station.

The insurance covers all employed workers in Japan, regardless of their nationality or labor status, who die or sustain injuries while working or commuting.

On the night he was killed, Lee, a 26-year-old student, was on his way home from an Internet cafe near the station where he had worked part-time since April, the owner said.
