Man (25) arrested under terror laws after unleashing 'noxious substance' that led to evacuation of London City Airport
A 25-year-old man has been arrested over a chemical incident that led to the evacuation of London City Airport.
The suspect was held on Saturday, accused of "using a noxious substance to cause serious damage" after dozens of passengers suffered breathing difficulties at the travel hub on Friday.
He has since been released on bail until late November, Scotland Yard said.
The force said in a statement: "Police arrested a man on Saturday, October 22 in connection with an incident at London City Airport on Friday, October 21.
"The man, 25, was arrested at a residential address in east London and taken to a west London police station.
"He was arrested on suspicion of using a noxious substance to cause serious damage - an offence under section 113 of the Anti-Terrorism, Crime and Security Act 2001.
"He has since been bailed pending further enquiries to a date in late November."
The alert saw around 500 members of the public and airport staff evacuated from the terminal.
Two casualties were taken to hospital and 25 were treated at the scene.
The closure of the airport led to travel chaos as all flights were suspended.
Several incoming planes from destinations such as Frankfurt, Amsterdam, Belfast City and Paris were diverted to other airports.
