An additional two individuals are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
