An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
