A North Korean man defected to South Korea on Sunday after crossing the border, Seoul's military said.
He was spotted at the northern part of the mouth of the Han River in Gimpo, just west of Seoul, according to Seoul's Joint Chiefs of Staff (JCS).
Questioning is under way to find out what caused him to flee to the South.
His defection marks the second in just a week. A North Korean solder defected to South Korea through the border Tuesday.
The two Koreas remain technically at war since the Korean War (1950-53) ended in a cease-fire, not a peace treaty. (Yonhap)
