TOKYO -- Police are investigating a Delta Air Lines flight from South Korea to Japan after a small knife was found under passenger seats, an official said Tuesday.
The Delta flight with 86 passengers and eight crew members arrived at Narita, Japan from Pusan, South Korea. Afterward, cleaners found a folding knife with a blade about 2.8 inches long under seats, a Narita airport police official said.
The police official declined to be named as he was not authorized to talk to the media.
A Delta spokeswoman in Tokyo could not be reached for comment.
The Atlanta-based airline had a similar incident last week. Its flight from Tokyo to Oregon was searched upon landing after its crew found box cutter blades aboard. The blades were found in the plane's cabin while en route to Oregon.
Authorities interviewed all 154 passengers and 10 crew members on the flight.
