A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
