An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
