An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
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, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and have since been released.
Police detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
