A controlled explosion was carried out at Luton Airport after a suspect car was found parked near the arrivals lounge on Thursday evening.
The departure terminal was evacuated and a 656ft (200m) cordon put in place as a precautionary measure.
No flights were allowed to depart from the airport, but some arrivals were not affected and some diverted to Stansted.
The airport has now reopened and is operating normally. Bedfordshire Police apologised to anyone affected.
