The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
