An unclaimed suitcase at the domestic airport here caused a flutter, as it was discovered minutes before Union Home Minister P Chidambaram's arrival here.
The home minister was scheduled to arrive from Madurai.
Earlier, the unclaimed suitcase sparked an alarm with the security agencies cordoning off the area with bomb disposal squad personnel checking it, airport sources said.
No suspicious articles were found in the suitcase and officials said it could have been left behind by some air passenger, they said.
