An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
