An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit 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 Terminal 3 this past Sunday. Before the incident, two women 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. Five people went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
