SEOUL, May 28 -- An arson attack caused fire at a subway train in the South Korean capital city of Seoul, local broadcaster YTN reported Wednesday.

The fire broke out at around 10:50 a.m. local time and was put out some 15 minutes later. One was injured with a sprained ankle, and no fatalities were reported.

The arsonist in his 60s sprayed an inflammable, known as paint thinner, within the train pulling into the Dogok station of the Line No. 3 in southern Seoul before lighting a fire.

He was arrested by police while receiving retreatment in a nearby hospital. The suspected arsonist said to police that he sought to kill himself for economic difficulties.

About 370 passengers were evacuated. The subways resumed normal operations from 12:10 p.m. local time after passing by the Dogok station without stoppage.
