An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, 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. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past 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 among the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
