An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
