An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
