Chennai: A spat between an Iranian couple mid-air forced a Bali-bound international flight to make an unscheduled landing here recently, airport officials said.

The incident happened on November 4 when the woman discovered her husband's affair mid-flight. She deftly used her husband's hand while he was sleeping to unlock his fingerprint-protected phone, revealing the alleged affair. The couple entered into an argument mid-air, with no amount of efforts by the flight crew to broker peace between them yielding fruit.

Subsequently, the pilot of the international airline sought permission to make an unscheduled stopover at Chennai and later offloaded the couple along with their child before resuming the journey to Bali in Indonesia, the officials said.

Immigration officials here kept the family at a room in the airport and later put them on a flight to Singapore.
