The All Nippon Airways flight was traveling from Japan’s Haneda Airport in Tokyo to George Bush Intercontinental Airport in Houston on Saturday when a passenger became “unruly,” according to the airline, which did not provide any details. Online records show that Flight 114 departed from Tokyo at around 10:33 a.m. local time.

A passenger caused an All Nippon Airways flight to divert after trying to open the exit doors mid-flight, authorities said.
