An additional two individuals have been arrested related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
