A man in his 40s has been arrested in West Sussex as part of an investigation into a cyber attack.
The incident caused disruption at Heathrow and other major European airports over the weekend.
He was arrested on suspicion of offences under the Computer Misuse Act and has since been released on bail.
Deputy Director Paul Foster, head of the NCA’s National Cyber Crime Unit, said: “Although this arrest is a positive step, the investigation into this incident is in its early stages and remains ongoing.”
“Cybercrime is a persistent global threat that continues to cause significant disruption to the UK. Alongside our partners here and overseas, the NCA is committed to reducing that threat in order to protect the British public.”
