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.
