An additional two individuals are now in custody in connection with a robbery 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 Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of several people hurt by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
