When the plane was taxiing to the runway for takeoff, a woman passenger started screaming that she found the MP3 player in her handbag though it was not hers.
This caused bombscare among the passengers and the crew members informed the pilot about the situation, the officials said.
After consultation with the Air Traffic Control, the aircraft was taken to an isolated bay and the woman, who was flying with her little daughter, was interrogated and the plane checked.
As nothing suspicious was found, the plane, which was scheduled to leave Kolkata at 7.30 PM, took off at about 9 PM, the officials said.
