An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for medical care and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
