These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
