Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of several people hurt by a noxious substance believed to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
