An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage 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 in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
