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 what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
