Police are studying CCTV images from across Gatwick Airport in a bid to identify two men who dumped a van in a North Terminal car park sparking a major security alert.
The blue Renault van was driven into the short stay car park on Wednesday afternoon.
When it was spotted, routine checks showed it to be unregistered, untaxed and uninsured and a call across the airport for the driver to return to the vehicle was not heeded.
As a result, police called upon an explosive ordnance disposal unit (EOD) who carried a controlled explosion.
Detective Inspector Rob McPhilemy from Gatwick CID said: "We are considering the very strong possibility that the two men who can be seen in the van on CCTV images, but not very clearly, dumped the van and then went into the airport and boarded a flight."
