The fight occurred on Monday on All Nippon Airways Flight 6, or NH6, aboard a Boeing 777 that was about to embark on an 11-hour journey to Los Angeles International Airport from Narita International Airport outside Tokyo.

Michihiko Aoi, a police official at Narita, said Wednesday evening that “a man of American nationality in his 40s was taken off NH6, as he had flown into a rage and caused trouble on the plane.” The man was drunk, he added.

Mr. Aoi’s statement continued: “Today, we received several phone inquiries from the news media asking about the video taken inside the plane. The man was not charged over the incident recorded inside the plane, but because of the violence he inflicted on the ANA official, causing scratches on his forehead.”

“We can’t comment on the video as we don’t know who took it, and also there are other people appearing in it,” Mr. Aoi added. “He was seen in the video, but we cannot confirm which one he is, or which color shirt he wore.”
