An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 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 - an event that authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
