Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator. A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for treatment and have since been released. Police arrested a 31-year-old man on suspicion of robbery and assault near the scene.

Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray. The attack - an event that police said was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
