An additional two individuals have been arrested in connection with a robbery 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 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
