An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 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 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later discharged.
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 alerted at about 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
