An additional two individuals have been arrested in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
