An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident 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 Terminal 3 car park for a short time.
