An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police arrested a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
