A 30-year-old man from Crawley arrested at Gatwick on Monday (June 3) has been detained under the Mental Health Act while an investigation continues.
The arrest followed a police response at 1.55am to an incident in the South Terminal when a man attempted to go through a staff search area openly carrying a kitchen knife in each hand.
The area was secured and the man was challenged by officers, who used Taser to detain him.
This is not being treated as terrorist-related.
The 30-year-old man from Crawley, who was not a travelling passenger, has been arrested on suspicion of possessing offensive weapons, affray and making threats to kill.
Superintendent Justin Burtenshaw said: “Officers at Gatwick are there to keep passengers and staff safe. This incident was dealt with swiftly and no members of the public or police were harmed.”
Anyone who saw what happened or who may have other relevant information is asked to contact Sussex Police online or phone 101, quoting serial 0089 of 03/06.
