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 law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a 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 Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - 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 Central Terminal Area tunnel and the Terminal 3 car park briefly.
