A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting 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 treatment and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
