UK police said Wednesday a man in his 40s had been arrested after a cyberattack caused travel chaos at major European airports including Brussels, Berlin and London’s Heathrow.

Axar.az informs, citing BBC, 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.
