Live ammunition found at Incheon International Airport... Police investigating = South Korea

Police have launched an investigation after a number of live ammunition were found at a garbage collection site at Incheon International Airport in South Korea.
More than 300 rounds of live ammunition were found at a garbage collection site on the east side of the airport. Incheon International Airport Police were dispatched to retrieve the ammunition and conducted a joint investigation with the relevant authorities, but no further suspicion of crime was found.
Authorities are considering the possibility that the departing American was unable to bring live ammunition on board and discarded it, and plan to conduct additional investigations, including fingerprint investigations.
