A 20-year-old military serviceman attempted to drown himself in the sea near the southern coastal city of Tongyeong, early on Friday morning.
The Tongyeong Korea Coastguard Station said the young man, surnamed Park, had implied he would try to take his own life in a phone conversation with his grandmother just prior to the suicide attempt.
His grandmother alerted the police, who passed the message on to the coastguard. At around 3:15 a.m., Park was found flailing in the waters around 10 meters away from a lighthouse in Misu-dong, Tongyeong.
The police said Park showed signs of hypothermia but was otherwise uninjured. The reason why he jumped into the sea is not yet known.
Park was based in Tongyeong, South Gyeongsang Province, for his mandatory military service.
He was dressed in civilian clothes when he was rescued from the sea.
