An All Nippon Airways flight en route from Los Angeles to Tokyo was forced to turn around four hours into the eleven hour journey to remove an "unauthorized person" from the flight, angering passengers who were told by the airline that passenger had a ticket for another airline.

A twitter user claiming to have been on board flight ANA 175 said that four people were questioned and detained; "1 Muslim,2 white, and 1 asian lady."

Police said the massive U-turn was due to a "mix up, and was straightened out," according to ABC7, and that the flight has been rescheduled to depart Wednesday morning.

Model Christine Teigen was aboard and documented the incident over Twitter.

Police were interviewing people seated near the mystery passenger, according to Teigen.
