An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Police detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted 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 - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
