The cellphone was found under one of the seats of the aircraft.
An Istanbul-bound flight of Turkish Airlines was called back from the runway in Mumbai today morning after an "unclaimed" mobile phone was found on a seat of the Boeing 777 plane.
The aircraft was brought back to the bay and all the passengers were deplaned for a thorough frisking.
The Boeing 777-300ER plane was scheduled to take off for Istanbul at 0625 hours.
"Turkish Airlines flight to Istanbul was called back from the runway at Mumbai airport after a suspicious object was found in the aircraft," a Mumbai Airport spokesperson said.
Airport sources, however, said it was an unclaimed mobile phone which forced the pilot to return the plane to the bay.
The flight has taken off after being cleared.
