An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area 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 follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
