Two more people have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
