HONOLULU (HawaiiNewsNow) - A Hawaiian Airlines flight heading for South Korea turned back Wednesday over concerns about a passenger.
The FBI said two passengers were detained and interviewed after the plane landed, and subsequently released.
"Our investigation indicates that the incident in question was not an intentional threat to the crew or passengers on board the plane," the FBI said, in a statement.
In a statement, Hawaiian Airlines said flight 459, bound for South Korea, returned to Honolulu "after flight attendants reported suspicious behavior by a passenger on board the aircraft."
The plane was met by law enforcement officials after landing safely in Honolulu at 8:35 p.m.
Some 285 passengers on the plan were able to depart for South Korea on a different plane.
Passenger Miguel McAdams Albarracin says the flight took off at 2:45 p.m. on Wednesday before turning around a few hours later.
Authorities have not gone into detail on what disruptive behavior prompted the plane's pilot to turn around.
