An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - which police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
