An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
