An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
