The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
