Bedfordshire Police has confirmed that a man in his 30s has been arrested in connection with a fire at a multi-storey car park at Luton Airport.
The fire broke out on level three of the car park on Tuesday, 10 October, causing the airport to close for several hours.
It is believed the fire started in a diesel car.
A Bedfordshire Police spokesman said: “Police arrested a man in his 30s on suspicion of criminal damage in connection to their investigation into a significant fire in a car park at London Luton Airport on Tuesday (10 October).
“We are carrying out a thorough and diligent investigation into all potential lines of enquiry, as should be expected after such a major event.”
The car park remains unsafe, with many cars still in situ. The DART transport service between Luton Airport Parkway station and the airport was suspended due to safety concerns but resumed at the weekend.
Police said: “The man has been released on bail while our enquiries continue.”
