An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for treatment and have since been released.
Police arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
