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 an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
