Two more people are now in custody in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an attack 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 toddler aged three was one of the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
