A person has been arrested in connection with a cyber-attack which has caused days of disruption at several European airports including Heathrow.
The National Crime Agency (NCA) said a man in his forties was arrested in West Sussex "as part of an investigation into a cyber incident impacting Collins Aerospace".
There have been hundreds of flight delays after Collins Aerospace baggage and check-in software used by several airlines failed, with some boarding passengers using pen and paper.
"Although this arrest is a positive step, the investigation into this incident is in its early stages and remains ongoing," said Paul Foster, head of the NCA's national cyber crime unit.
The man was arrested on Tuesday evening on suspicion of Computer Misuse Act offences and has been released on bail.
