An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected 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 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of theft 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 after reports came in regarding a number of individuals hurt by an irritating chemical 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.
