The Army Bomb Squad was called in to Shannon Airport yesterday amid concerns over a suspect device in the luggage of a passenger.
A plane travelling from Kuwait to New York stopped at Shannon Airport and a mobile phone in the luggage of a passenger showed up as suspect during pre-clearance.
The phone was removed to a safe area and the Army EOD team was notified.
The smoking areas of the airport were evacuated for a time, following which the device was declared safe.
Gardaí say the passenger assisted them in their inquiries and has since traveled on to New York.
