A man has been arrested following yesterday's evacuation of terminal four at Heathrow Airport.
Yesterday afternoon, the terminal was evacuated after around 20 people reported injuries following what was described as a 'potential hazardous materials incident'.
Specialist officers dispatched to the scene and conducted a thorough search of the area.
Sky News report that following the search, a canister of what is believed to be CS spray was located.
The Met Police said in a statement: "It is thought that this substance caused a reaction to those within the airport."
A 57-year-old man has been arrested on suspicion of possession of a firearm (CS spray) and of causing a public nuisance.
The incident is not being treated as terrorism.
The man remains in police custody.
