An additional two individuals have been arrested related to a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been 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 while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
