A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
