SEOUL, South Korea - An Asiana plane with 259 passengers aboard returned to Hong Kong on Monday after finding a wrong passenger was aboard the aircraft, airline officials said.

The plane was bound for Incheon, South Korea, when it had left Hong Kong earlier Monday. But it began flying back to Hong Kong when it was above Taiwan, Asiana Airlines officials said, speaking on condition of anonymity because their company was still checking details of the incident.

The passenger, believed to be a South Korean, was supposed to take a Jeju Air plane from Hong Kong to Incheon but that it wasn't known how he got on a wrong plane, according to Asiana Airlines.

The Jeju Air plane was to leave Hong Kong 40 minutes later than the Asiana plane, Asiana officials said.

They said police would question the passenger at Hong Kong's airport.

An Asiana plane crash-landed at the San Francisco airport in 2013, killing three passengers and injuring nearly 200 people.
